For loops

The following C code iterates over the characters of a string. I’ve never thought to write code this way, but of course you can.

#include <stdio.h>

int main() {
    const char *text = "testtest";
    int n = 0;
    int i;
    for (i=0; text[i] != '\0'; ++i) {
        n++;
    }
    printf("%d\n", n);
}
