Following is the solution to your question, answer to part 1 and 2 are designated by comment.

#include <cstdlib>
#include <iostream>
#include <string>
#include <fstream>

using namespace std;

//solution to part 1

void Payit(double money, double* amountPtr)
{
if (*amountPtr>= money)
{
*amountPtr-=money;
}
}

//solution to part 2

int main()
{
double balance = 200.00;
double moneyToPay = 100;

cout<<\"Before payment, balance is :\"<<balance<<endl;
Payit(moneyToPay,&balance);
