Note: It is checked verified method still if there is any minute trouble do ask me or ChatGPT like ai tools. Day 1: Introduction to DSA and Environment Setup Download the vs code required extensions then set-up your ide Day 1: Setting Up Your IDE Like a Pro Introduction When starting your coding journey, having an organized environment can significantly boost your productivity and ease the debugging process. Today, we’ll walk you through setting up your IDE using a JSON file to manage your coding files, input, and output separately. We’ll cover setups for Java, C++, and Python. Step 1: Why Use a JSON File? Using a JSON file to organize your projects helps in keeping your code, input, and output files separate, making it easier to manage and test your programs. It also allows for easy switching between different languages and projects. Step 2: Creating Your Project Structure (It can vary on every individual this is just an example) First, let’s create a directory structure: bash Copy code /my_project ├── code/ │ ├── main.cpp (or main.java, main.py) ├── input/ │ ├── input.txt ├── output/ │ ├── output.txt ├── config.json • code/: This folder contains your main source code file. • input/: Place your input files here. • output/: Your program’s output will be stored here. • config.json: This file will manage the paths and commands for running your program. Step 3: Writing the JSON Configuration Note : for windows users : it will not work if your default terminal is Powershell make it cmd then it will work. to change default terminal : press->clt+shift+p->write:default terminal->change it to cmd Create a config.json file in your project directory. C++ : { "version": "2.0.0", "tasks": [ { "label": "Compile and run C++", "type": "shell", "command": "g++", "args": [ "-std=c++17", "-O2", "${file}", "-o", "${fileDirname}\\${fileBasenameNoExtension}.exe", "&&", "${fileDirname}\\${fileBasenameNoExtension}.exe", "", "output.txt", "&&", "del", "${fileDirname}\\${fileBasenameNoExtension}.exe" ], "group": { "kind": "build", "isDefault": true }, "problemMatcher": ["$gcc"] } ] } For Java: { "version": "2.0.0", "tasks": [ { "label": "Compile and run Java", "type": "shell", "command": "javac", "args": [ "${file}", "&&", "java", "-cp", "${fileDirname}", "${fileBasenameNoExtension}", "", "output.txt" ], "group": { "kind": "build", "isDefault": true }, "problemMatcher": ["$javac"] } ] } Python: { "version": "2.0.0", "tasks": [ { "label": "Run Python", "type": "shell", "command": "python", "args": [ "${file}", "", "output.txt" ], "group": { "kind": "build", "isDefault": true }, "problemMatcher": ["$python"] } ] } These configurations will work for their respective languages, using input.txt for input and writing to output.txt for output. Conclusion With this setup, you’ll have a neatly organized workspace where your code, input, and output are separated, making testing and debugging your programs easier. This structure is a best practice for professionals.
*OUTPUT NOT PRINTING ISSUE FIX IN WINDOWS* Step 1: Replace the following line "${workspaceFolder}\\jspwTest.cpp", with "\"${workspaceFolder}\\jspwTest.cpp\"", Step 2: 1: Go to setting icon of vs code in lower left corner. 2: Go to setting option (where shortcut is showing ctrl+,). 3:search for default terminal. 4: here select the default terminal profile for Windows and change it to command prompt.
Hi, i had setup my vs code for c++ seeing your video for it, i have a few doubts: now my normal run code button doesnt run in cases where i need to give an input, secondly everytime for an output i have to write ctrl+shift+b?

Thanks Raj bhaiya for this configuration file, it is working completely fine with some minor modification using chatgpt. But it stuck when I accidentally execute infinite loop. Can you tell how to add time limit for execution similarly like we have on competitive platforms.
Yes there is Go to keyboard shortcuts and search the shortcut which is already there I think ctrl shift p it is so search that shortcut, like just search ctrl shift p and change it to whatever you want I have changed it to Alt + X
if facing errpr while running the java file, go to tasks.json and change label a liitle bit ...suppose Compile and Run. In my case, it worked after doing this, earlier the cpp task file was always getting run in java also.

you are doing a mistake as you are running in windows powershell terminal and not in command prompt terminal and in new version of vs code you cannot change your default terminal as shown by other youtubers, for changing try following this steps: 1: Go to setting icon of vs code in lower left corner. 2: Go to setting option (where shortcut is showing ctrl+,). 3:search for default terminal. 4: here select the default terminal profile for Windows and change it to command prompt. NOTE : You need to change from workspace (it is just below the search bar where you had type default terminal) ,if you change from user side it will not change ,also it was the error from the beginning because you were changing default terminal from the user side and not the workspace side
i can tell you are running in powershell terminal because it is written in your path C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe (see you are running in powershell.exe) if you were ran this code in command prompt it had shown cmd.exe and striver bhaiya already said you have to run in command prompt terminal for working and not in powershell terminal

So, yeah for me, it wasn't as simple as that but the AI ChatGPT, helped a lot.
In my case, the code was compiling and running if both are done separately, Ctrl + Shift + B compiled the program and Ctrl+Shift+P > Run tasks > Run with input or output used to put the output in Output.txt.
ChatGPT said the following steps, will work according to the case that C++ file is main.cpp ,input file is input.txt ,and output file is output.txt
1. Create the file build_and_run.bat and write the prompt in it
@echo off
g++ main.cpp -o main.exe
main.exe < input.txt > output.txt
2. Next, change the json prompt to the following:
{
"version": "2.0.0",
"tasks": [
{
"label": "Compile and Run with Input and Output",
"type": "shell",
"command": "${workspaceFolder}\\build_and_run.bat",
"group": {
"kind": "build",
"isDefault": true
},
"detail": "Compiles and runs the program with input redirection and writes output to output.txt"
}
]
}
The next time you use Ctrl + Shift + B, it will compile and run too.
Hope it helps 👍

Edit: I found the solution, there is a direct file tasks.json in the .vscode file. Just show hidden files and you will find it.
Replace the following line "${workspaceFolder}\\jspwTest.cpp", with "\"${workspaceFolder}\\jspwTest.cpp\"", if output is not generating
WORKS ! DAMN thanks so much
Thanks a lot. Working just like that.

Day 1: Introduction to DSA and Environment Setup
Download the vs code required extensions then set-up your ide
Day 1: Setting Up Your IDE Like a Pro
Introduction
When starting your coding journey, having an organized environment can significantly boost your productivity and ease the debugging process. Today, we’ll walk you through setting up your IDE using a JSON file to manage your coding files, input, and output separately. We’ll cover setups for Java, C++, and Python.
Step 1: Why Use a JSON File?
Using a JSON file to organize your projects helps in keeping your code, input, and output files separate, making it easier to manage and test your programs. It also allows for easy switching between different languages and projects.
Step 2: Creating Your Project Structure (It can vary on every individual this is just an example)
First, let’s create a directory structure:
bash
Copy code
/my_project
├── code/
│ ├── main.cpp (or main.java, main.py)
├── input/
│ ├── input.txt
├── output/
│ ├── output.txt
├── config.json
• code/: This folder contains your main source code file.
• input/: Place your input files here.
• output/: Your program’s output will be stored here.
• config.json: This file will manage the paths and commands for running your program.
Step 3: Writing the JSON Configuration
Note : for windows users : it will not work if your default terminal is Powershell make it cmd then it will work. to change default terminal : press->clt+shift+p->write:default terminal->change it to cmd
Create a config.json file in your project directory.
C++ :
{
"version": "2.0.0",
"tasks": [
{
"label": "Compile and run C++",
"type": "shell",
"command": "g++",
"args": [
"-std=c++17",
"-O2",
"${file}",
"-o",
"${fileDirname}\\${fileBasenameNoExtension}.exe",
"&&",
"${fileDirname}\\${fileBasenameNoExtension}.exe",
"",
"output.txt",
"&&",
"del",
"${fileDirname}\\${fileBasenameNoExtension}.exe"
],
"group": {
"kind": "build",
"isDefault": true
},
"problemMatcher": ["$gcc"]
}
]
}
For Java:
{
"version": "2.0.0",
"tasks": [
{
"label": "Compile and run Java",
"type": "shell",
"command": "javac",
"args": [
"${file}",
"&&",
"java",
"-cp",
"${fileDirname}",
"${fileBasenameNoExtension}",
"",
"output.txt"
],
"group": {
"kind": "build",
"isDefault": true
},
"problemMatcher": ["$javac"]
}
]
}
Python:
{
"version": "2.0.0",
"tasks": [
{
"label": "Run Python",
"type": "shell",
"command": "python",
"args": [
"${file}",
"",
"output.txt"
],
"group": {
"kind": "build",
"isDefault": true
},
"problemMatcher": ["$python"]
}
]
}
These configurations will work for their respective languages, using input.txt for input and writing to output.txt for output.
Conclusion
With this setup, you’ll have a neatly organized workspace where your code, input, and output are separated, making testing and debugging your programs easier. This structure is a best practice for professionals.

did you get any solution yet ?
@@rajkumarchaudhary6783 yes brother, working fine
basically i used the same template as provided, just insure that the path in which you have saved the folder or your cpp file, make sure the name of any folder should not contain spaces. For eg. if you have a folder named "abc def" make it "abc_def", that was the mistake i was doing, maybe helpful for you
Thanks Striver 🙌

I'm also having similar problem
😢
you are doing a mistake as you are running in windows powershell terminal and not in command prompt terminal and in new version of vs code you cannot change your default terminal as shown by other youtubers, for changing try following this steps:
1: Go to setting icon of vs code in lower left corner.
2: Go to setting option (where shortcut is showing ctrl+,).
3:search for default terminal.
4: here select the default terminal profile for Windows and change it to command prompt.
NOTE : You need to change from workspace (it is just below the search bar where you had type default terminal) ,if you change from user side it will not change ,also it was the error from the beginning because you were changing default terminal from the user side and not the workspace side
i can tell you are running in powershell terminal because it is written in your path C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe (see you are running in powershell.exe) if you were ran this code in command prompt it had shown cmd.exe and striver bhaiya already said you have to run in command prompt terminal for working and not in powershell terminal
