same as harry 🤣 good
Well try

Sound ko bhi integer data type me rakha hai
Sound ko string ya character data type me rakhna chahiye tha

Q 1: Write a C++ function “addition” that will take two arguments “istVal” and “secVal” as integer
arguments and the function will add the values of “istVal” and “secVal” and return the result to
the calling statement in main function.

string requires header file right?
@@myth_snipe7737no its not required you can define string variables in c++ if you want to use string functions than the string.h header file required
@@unknownking798most welcome bro ❤
If we don't declare access modifier to any variable and function by default it get private.
great course harry
Thanks Harry Bhaiya
Heyy Sir make more videos as soon as possible..my exams will start from mid of march

enjoy!!! :D
tera naukar h kya wo?
Ok
to padai karo to lecture bunk mat maro
Sir, in a class, you explained private and public modifiers. But what are protected modifiers?
protected modifiers have properties of both public and private modifiers. You can inherite properties from a protected modifiers but it will still be private for the user.
in protected data members of one class can be accessed outside of the class that is in another class
@@maazsajid5742 *subclass or inherited class
Thanks Bhaiya
Thank you very much sirji 🙏🏻🙏🏻
Sir, Are the content(variables + functions) written in the public category up to the end of the class '}' is considered as public or it gets terminated after the semicolon; at the end of the next line where public was written?
All the variable or function can be written either in private or in public depending on your choice or situation.
doesn't get terminated after; but terminated or we can say considered up to }
Thank you, Harry bhai!
very good explaination.
Could we get some questions for this chapter?
sir if we write those functions under private as you have written them under public can we use them in main program??
nope
@@revanthkumar1789 No bro
Thank you so much sir 😊😃💝
Thank you! 😇
there is the only difference between structure and classes in cpp that is default access specifier:
In struct it is public and in class it is private.
Inheritance can be used in structures
Class Students {
Private :
int mobileNo;
string address;
Public:
Int rollNo;
String name;
Void putdata(int mob , string addr);
Void showdata ()
{
Cout
Sister Baki program sahi hai but
mobile No, address ko cout karwa hi nahi
Great efforts
Thank you Harry bhaii!🥳

class Room

double calculateArea(){

} double calculateVolume(){

why you are defining your area function here, its very hard to read here,
Where is private keyword???
Nice video!
bro we can make functions using struct
the only difference between struct and class is by default in struct variables are public whereas in class they are private.
And i think the inheritance feature also
adarsh mishra not only inheritance there are many class properties which you can see in prev-vedio or search about it. So bcoz of that all properties of class makes a huge diff between structure and class
No in structure we cannot define Functions, and the solution of this is class🤟🏼
If you are using struct in cpp than there us no difference in class or struct...... You can also use the concept of inheritance in struct .... Know your fact before talking

Sir jab ham koi program run karte hai, tab compiler sabse pehele program ke konse part me jata hai ??
Just a small correction, access modifiers exist in structures also
and also structures in c++ allows function definition inside the structure
#include
#include
using namespace std;
// 14:57
class Animal
{
public:
string name,sound;
int speed;
void set_animal_data(string parm_name,string param_sound,int param_speed);
void get_animal_data();

void Animal :: set_animal_data(string param_name,string param_sound,int param_speed){
name = param_name;
sound = param_sound;
speed = param_speed;
}
void Animal :: get_animal_data(){
cout
get_animal_data function m cout nhi krna?? ?
Nikhil, here you use
in cpp . Can we use this because this is for c and in cpp there is alternate called
@@harshprajapat165 Yup! You can use it
@@prernaprerna4028 why bro get_animal_data function me he krna h
Thanks man ❤️
void class name::function name(arguments);
Harry bhai can we use "void setData and getData" for public function
plz reply I am waiting for your reply
Functions are created for private use only... Set data... Is used bcoz we want to access the private variables through function... And get data is jst to print it.. To access the public variable we don't need functions we can directly access it.. By using dot..
Vaiya next videos Kab ayega?
