I didn't use return part in the recursive part and it still works

#1

This is my function for storing all the occurrences.
int storeocc(int *a, int i, int j, int n, int *out, int key){

if(i==n){
    return j;
}
if(a[i]==key){
    out[j]=i;
    j++;
}
storeocc(a, i+1, j, n, out, key);// here i didn't right return

}

However, in the video, it has a return part there. I want to ask whether it is necessary or not to write the return part.

hello @amanb25

your function return type is int so ur function must return integer to calling function and thats why return is mandatory.

try again , ur compiler should show error like function not returning anything.

I do not get any error.
