How to set values to int array using memset in C

Answer 1

#include <stdio.h>
#include <string.h>

int main() {
    int arr[5] = {1, 2, 3, 4, 5};

    // void *memset(void *str, int c, size_t n) 
  
    // str − A pointer to the block of memory to fill

    // c − The value to be set

    // n − The number of bytes to be set

    memset(arr, 0, 8); // set 0 to first two int values (int - 4 bytes)

    for (int i = 0; i < 5; i++) {
        printf("%d ", arr[i]);
    }
  
    return 0;
}
