#include<studio>
void update(int *a ,int *b){ *a+=*b; *b=abs(*a -(2* *b));}
int main(){int a,b;
//int *pa=&a,*pb=&b;
Scanf("%d %d", &a, &b);
//update(pa,pb);
Update(a,b);
Return 0;

Answer 1

please kindly write your code on code play ground and link it here

edit, you need to pass the address of the variable as parameter in the function, wince its not an array

#include<stdio.h>
#include <stdlib.h>
int update(int *a ,int *b){ *a+=*b; *b=abs(*a -(2* *b)); return *b;}
int main(){int a,b;
//int *pa=&a,*pb=&b;
scanf("%d %d", &a, &b);
//update(pa,pb);
printf("%d",update(&a,&b));
return 0;
}
thats your code now working fine
