A small correct at 5:20 The statement `int arr[10] = {};` is legal in C, but its interpretation and behavior might not be immediately clear to all compilers, depending on the C standard they adhere to. Explanation: 1. **C99 and later**: - In C99 and later standards, you can initialize an array with `{}`. This is called a "universal zero initializer". It means that all elements of the array will be initialized to zero. - The statement `int arr[10] = {};` will initialize all elements of `arr` to `0`. 2. **Pre-C99**: - In C89/90 (the earlier C standard), the empty braces `{}` as an initializer might not be explicitly supported, and this could lead to a compiler error or warning. - Instead, you would typically initialize an array explicitly or with `{0}`: ```c int arr[10] = {0}; // All elements initialized to 0. ``` Example in Code: ```c #include int main() { int arr[10] = {}; // Legal in C99 and later for(int i = 0; i < 10; i++) { printf("%d ", arr[i]); } return 0; } ``` Compatibility: - If you are using a compiler that supports C99 or later, the code should compile and run without issues, initializing all elements to zero. - If using an older compiler that does not support C99, you may get an error or warning. In such cases, use `int arr[10] = {0};` for compatibility. ### Conclusion: - `int arr[10] = {};` is legal and initializes all elements to zero in C99 and later. - For maximum compatibility with older C standards, use `int arr[10] = {0};`.
5:00 int arr[10] = {}; works in 2023. The c complier may be updated. I tested this using both gcc and clang. Here is the test code : #include int main() { int a[10] = {}; for ( int i = 0; i < 10; i++ ) printf("a[%d] = %d ", i, a[i]); return 0; }
Hey, at 3:45 the garbage value at first gives 0 for the length if it exceeds by 1 but if I use more memory for rest of the unspecified bits it gives/allocates some garbage value to the array.
Write a program that initialize array of size 10, and prints all Armstrong and Palindrome numbers in array. Your program should ask user about their choice of printing. If user press ‘A’ or ‘a’ then program should display all Armstrong numbers in array and if user press ‘P’ or ‘p’ then it should display all Palindrome numbers in array.
in the topic Initializing Array @5:17 to 5:25. you mentioned that you cant add more elements to an array than the specified size of the array. This happens to not be the case as C actually allows you to add more elements than the size array which of course could lead to a lot of problems but I think its worth noting as it appears to be a weakness with the c programming language
Sir, first of all, thank you that you make such good videos for us free of cost, but sir, I have a request that along with understanding, please provide us notes to write in the exam, because i dont know how to write in the exam.
if you write int arr[SIZE] = {0}; Only the first element will get the value zero and the rest are filled automatically by the compiler, try changing 0 to 1 and see the difference
If I declare an array of type float and initialise the first value as 0.0f. Will the rest of the values also be initialised as 0.0f? Example: float array[5] = {0.0f}; The reason I ask is because I'm working with a microcontroller and calculations on a float value will be done with double precision and not single precision unless I specify 0.0f and I don't need the extra accuracy but need to save computation time.
hi! just came across this video while roaming around, am very interested in learning programming, and was looking for definition of an array, any advise where can I start ?
1) int arr[5]; arr[5]={1,2,3,4,5}; Why is this code showing error? 2) int ar[5]={}; Sir, even this code works fine in VS code.....in fact, this is the easiest way to initialize an array with all zero.
We cannot initialize and declare arrays separately like that. U can do only if u are assigning one element at a time. Ex : int arr[5]; arr[0] = 1; arr[1] = 2; arr[2] = 3; arr[3] = 4; arr[4] = 5;
@@meowrbius arr[5] means you are accessing the 5th index of arr array(actually not initialising the array), If you have already declared array then you have to use method-3,4 not 1, to declare, define and intialize you can do int arr[5] = {1 ,2, 3, 4, 5}
Great sir. Neso Academy's way of explanation is really exciting. Would love to see you get more views by people such as me❤
Videos from Neso Academy are absolute gold. Pure concept.
thank you so muuuuch from Germany Sir

A small correct at 5:20 The statement `int arr[10] = {};` is legal in C, but its interpretation and behavior might not be immediately clear to all compilers, depending on the C standard they adhere to.
Explanation:
1. **C99 and later**:
- In C99 and later standards, you can initialize an array with `{}`. This is called a "universal zero initializer". It means that all elements of the array will be initialized to zero.
- The statement `int arr[10] = {};` will initialize all elements of `arr` to `0`.
2. **Pre-C99**:
- In C89/90 (the earlier C standard), the empty braces `{}` as an initializer might not be explicitly supported, and this could lead to a compiler error or warning.
- Instead, you would typically initialize an array explicitly or with `{0}`:
```c
int arr[10] = {0}; // All elements initialized to 0.
```
Example in Code:
```c
#include
int main() {
int arr[10] = {}; // Legal in C99 and later
for(int i = 0; i < 10; i++) {
printf("%d ", arr[i]);
}
return 0;
}
```
Compatibility:
- If you are using a compiler that supports C99 or later, the code should compile and run without issues, initializing all elements to zero.
- If using an older compiler that does not support C99, you may get an error or warning. In such cases, use `int arr[10] = {0};` for compatibility.
### Conclusion:
- `int arr[10] = {};` is legal and initializes all elements to zero in C99 and later.

Great lectures Sir, this is so detailed.
Is it possible to declare a 1D array like so;
int arr[] = {0};
yes of course it is a valid element. 0 is of data type int so it is a valid array arr[]
Write a program that initialize array of size 10, and prints all Armstrong and Palindrome numbers in array. Your program should ask user about their choice of printing. If user press ‘A’ or ‘a’ then program should display all Armstrong numbers in array and if user press ‘P’ or ‘p’ then it should display all Palindrome numbers in array.

Sir at 3:40 my sir told that it store garbage value instead of 0's to save time and working 🙄
Other please correct me🙏all who ever know this
if you write

Only the first element will get the value zero and the rest are filled automatically by the compiler, try changing 0 to 1 and see the difference
why increment in method 4 in initialising a 1d array
4:51 its not illegal it works actually it will be filled by value of zero
waiting for u r next videooo....if u fastly upload u r videos it will helpfull for those people who are now learn c...
Very useful for me.

int a[5]={}; still initializes all array elements to zero why is this illegal?\
You are good, sir, I am just smiling😁
If I declare an array of type float and initialise the first value as 0.0f. Will the rest of the values also be initialised as 0.0f? Example: float array[5] = {0.0f}; The reason I ask is because I'm working with a microcontroller and calculations on a float value will be done with double precision and not single precision unless I specify 0.0f and I don't need the extra accuracy but need to save computation time.
in method 1 and 2 how can you initialize array not at declaration?
Can you explain about global array? please
Sir , by keeping array size empty we can store any number of values
The illegal cases that u explained are not illegal at all. They are working just fine

nice sir
sir but when input is greater than the length of the array,it's workinf fine It's not showing any error

No 1 value will allocated to first block other will get 0 values
