Answer 4

Sankar Zaya something like this ....

#include <stdio.h>

int main() {
int arr[] = {10, 20, 30, 40, 50};
int size = sizeof(arr) / sizeof(arr[0]);
int target = 30;
for (int j = 0; j < size; j++){
if (arr[j] == target){
printf("%d ",j); // index of target
}
}
return 0;
}

Answer 5

BroFar why would you do it that way over

let arr=[10,20,30,40];
let index= arr.indexOf(30);
console.log(index)

Or does your way also work for c while mine in only Javascript? Because what you did doesn’t look to me like c, although I really don’t know much about c, but it does look like javascript.
