Write a function swap to swap two int values. For instance, we have two variables int a, b and a=10,b=5. After the function swap is called, we should have a=5, b=10 . If we define a function like void swap(int a, int b) , there is no way for us to call this function to swap the values of two int variables. The following program will not help to swap the values. You can think about other ways to implement the function void swap(int a, int b) but you are unlikely to succeed. void swap(int a, int b) { int c = a; a = b; b = c; } int main() { int a, b; cin >> a; cin >> b; swap(a, b); Try to use pointers to solve this problem (e.g., defining a function like void swap(int *a, int *b) ).
