    #include <stdio.h>

void update(int *a,int *b) {
    int temp = *a;
    temp = *a + *b;
    *b = *a - *b;
    if (*b<0){
        *b = *b*(-1);

    int *pa = &a, *pb = &b;
    
    scanf("%d %d", &a, &b);
    update(pa, pb);
    printf("%d\n%d", a, b);

    I used the abs() function within cstdlib library

    #include <stdio.h>
#include<cstdlib>

void update(int *a,int *b) {
    int sum = *a + *b;
    int diff = abs(*a-*b);
    
    *a = sum;
    *b = diff;

}

    void update(int *a,int *b) { *a = *b + *a; *b = abs(*a - 2 * *b);
    }

    C++ Just tried on bare numbers to get the example work and it worked for all test cases xD
