I have a class screen and a class Brush both have header files and source files. The driver file shown first was provided to us so nothing should be wrong with it but I wanted to show you how it worked.
#include <iostream>
#include <string>
#include "Screen.h"
#include "Brush.h"
using std::cin;
using std::cout;
using std::endl;
using std::string;
int main()
{
// function prototype
void print_menu();
screen S;
Brush B;
bool IMFlag = true;
bool QuitFlag = false;
string Command;
char NewColor;
int NewWidth, NewHeight;
int NewRow, NewColumn;
char NewWord[81];
S.clear();
print_menu();
// This is the large loop controlling the activities.
while (!QuitFlag)
{
cin >> Command;
if (Command == "Q")
QuitFlag = true;
else if (Command == "CS")
S.clear();
else if (Command == "DISP")
S.print();
else if (Command == "NI")
IMFlag = false;
else if (Command == "IN")
IMFlag = true;
else if (Command == "BP")
{
if (IMFlag) cout << "At what row and column should we draw?" << endl;
cin >> NewRow >> NewColumn;
B.draw_position(S, NewRow, NewColumn);
}
else if (Command == "BC")
{
if (IMFlag) cout << "What is the new color?" << endl;
cin >> NewColor;
B.set_color(NewColor);
}
else if (Command == "BS")
{
if (IMFlag) cout << "What are the new width and height?" << endl;
cin >> NewWidth >> NewHeight;
B.set_size(NewWidth, NewHeight);
}
else if (Command == "BU")
