Exam 01 Piscine 42 Exclusive Guide

In the 42 exam environment, you cannot copy-paste from the internet, but you can copy-paste within your own terminal. Write a standard template:

#include <unistd.h>
// Function here
int main(void) // Hidden from Moulinette, but useful for your own testing
ft_putstr("Hello Exam 01");
return (0);

Exclusive trick: Comment out your main before grademe. Moulinette expects only the function. If you leave main in, you get a compilation error (score -42).

The XOR (exclusive OR) operation yields 1 when bits differ and 0 when they are the same.

Truth table:

| A | B | A XOR B | |---|---|---------| | 0 | 0 | 0 | | 0 | 1 | 1 | | 1 | 0 | 1 | | 1 | 1 | 0 |

In C, the ^ operator performs bitwise XOR.
