void point(int *a,int *b) { int *c; *c=*a; *a=*a+*b; *b=abs(*c-*b); }

Here are the solution of Pointer in C++ Hacker Rank Solution

void update(int *a,int *b) { // Complete this function
int x; int y; if(*a > *b){ x = (*a + *b); y = (*a - *b); *a = x; *b = y; } else { x = (*a + *b); y = *b - *a; *a = x; *b = y; }
