Question

int count(int *a, int *b, int n) {
    int i=0,j=0,roz=0;

    while(i<n) {
        while(j<n) {
            if(a[i]==b[j])
                roz++;
            j++;
        }
        i++;
    }
    return roz;
}

n is the size of a, or b array (both are of the same size). The nested while loop seems to work only once, for i = 0. The next thing that seems to be happening is magically changing n into 1 (it is 5 at the beginning), so that the nested while doesn’t loop the second time. Why is that so?

The interesting thing is that echoing n right before the return displays the right value, which is 5…

EDIT. For loops work properly here, but the question is still present.

Answer 1

You never reset the value of j to 0.
