You have to complete the function void update(int *a,int *b), which reads two integers as argument, and sets a with the sum of them, and b with the absolute difference of them.
- #include <iostream>
- using namespace std;
-
- void update(int *a,int *b)
- {
- int temp = *a;
- *a = *a + *b;
- *b = temp - *b;
-
- if(*b < 0)
- {
- *b = -(*b);
- }
- }
-
- int main()
- {
- int a, b;
- int *pa = &a, *pb = &b;
-
- cin>>a>>b;
- update(pa, pb);
- cout<<a<<"\n"<<b;
-
- return 0;
- }
