How to perform bitwise logical operations on strings in C?

Answer 1

#include <stdio.h>

void xorStrings(char* left, char* right) {
    int index = 0;

    while (left[index] != 0 && right[index] != 0) {
        left[index] ^= right[index];  // change operation here
        index++;
    } 
}

int main() {
    char a[] = "hello, world!";
    char b[] = "    ,foobar";

    printf("Before:\n%s \n %s\n", a, b);
    xorStrings(a, b);
    printf("After:\n%s \n %s\n", a, b);

    return 0;
}
