You have to complete the function void update(int *a,int *b), which reads two integers as argument, and sets with the sum of them, and b with the absolute difference of them.
- #include <stdio.h>
-
- void update(int *a,int *b) {
- *a=*a+(*b);
- *b=(*a)-(*b)-(*b);
- if(*b<0)
- {
-
- *b=*b*(-1);
- }
-
- }
-
- 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;
- }
