Jfl I forgot the int x, y; syntax

void inplace_swap(int *x, int *y){}

Something like that

 

[_wayland]

#include <stdio.h>
#include <unistd.h>

void inplace_swap(int *x, int *y){

        *x ^= *y;
        *y ^= *x;
        *x ^= *y;

}

int main(void){
   
        int x = 0;
        int y = 1;
     
    printf("\tx = %d y = %d\n", x , y);
    inplace_swap(&x , & y);
    printf("\tx = %d y = %d\n", x , y);

    write(1, "\n\tHello World\n", 15);

}

I counted wrong

 

[_wayland]

too lazy but I was gonna convert get rid of stdio entirely and use unistd.h

 

[Deleted Member 126149]

Counting hurts

At least wasn't a buffer overrun

would be too complicated for one file icl

I'll do asm syscalls tomorrow
