Hints

Subtracting two pointers into the same array gives the number of elements between them.

Solution explanation

This is essentially how the real strlen is implemented.

Show solution

#include <stdio.h>

int my_strlen(char *s) {
    char *p = s;
    while (*p != '\0') p++;
    return p - s;
}

int main() {
    int n;
    char w[100];
    scanf("%d", &n);
    for (int i = 0; i < n; i++) {
        scanf("%s", w);
        printf("%d\n", my_strlen(w));
    }
    return 0;
}
