In function ReplaceWeight(), if weightPointer is null, print "weightPointer is null.". Otherwise, assign weightValue to the variak pointed to by weightPointer. End with a newline. Ex: If the input is Y3, then the output is: Weight is 3 . \#include using namespace std; void ReplaceWeight (int* weightPointer, int weightValue) f / Your code goes here */ \} int main() 1 int weight; int* weightPointer; char action; int value; weight =0; cin action; cin >> value; if (action == ' Y ') \& weightPointer = weight; \} else \{ weightPointer = nullptr; \} ReplaceWeight (weightPointer, value); cout
