include

void update(int *a,int *b) { // Complete this function int val, val2; val = *a + *b; val2 = *b-*a; *a = val; *b = val2;

}

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;

}

what's wrong with this code? Why isn't this working?

What's wrong with

int z =*a+*b; *b=abs(*a-*b); *a=z; the prevention of the value update problem is to simply add a new variable.
