CNS Lab Exercise -1

Exercise-1

1. Write a C program that contains a string (char pointer) with a value \Hello World’. The program should XOR each character in this string with 0 and displays the result.

#include <stdio.h>

int main() {

    const char *str = "Hello World";

    int i = 0;

    printf("Result after XOR with 0:\n");

    while (str[i] != '\0') {

        char result = str[i] ^ 0;  // XOR with 0

        printf("%c", result);

        i++;

    }

    printf("\n");  // newline for neat output

    return 0;

}

Sample Output:

Result after XOR with 0:

Hello World
