    easy way to solve the problem

    void update(int *a,int *b) { // Complete this function

        int sum , diff;
sum = *a + *b;

diff = *a - *b;
if (diff < 0) diff = -(diff);

*a = sum;
*b = diff;

    }

    int main() {

        int a, b;
int *pa = &a, *pb = &b;

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

return 0;

    }

    here mine
#include <cmath>
#include <cstdio>
#include <vector>
#include <iostream>
#include <algorithm>
using namespace std;

int tambah(int *a,int *b){
    int total =*a+*b;
    cout<<total<<endl;
    return total;
}

int kurang(int *a,int *b){
    int total =abs(*a-*b);
    cout<<total<<endl;
    return total;
}

int main() {````````````````
    int a;
    int b;
    cin>>a>>b;
    tambah(&a,&b);
    kurang(&a,&b);  
    return 0;
}

    May be helpful you understand the stdlib.h

    #include <stdio.h>
#include <stdlib.h>

void update(int *a,int *b) {
    // Complete this function   
    int temp=(*b)+(*a);
    *b=abs((*a)-(*b));
    *a = temp;
}

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

    return 0;
}

    //Good luck

    include

    void update(int *a,int *b) { // Complete this function
    int c=*a,d=*b; *a=c+d; *b=c-d; if(*b<0) *b=-(*b);

    }

    int main() { int a, b; int *pa = &a, *pb = &b;

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

return 0;

    }
