How can I draw a line with a variable of width?

#include <iostream>
#include <cmath>
#include "graph1.h"
using namespace std;
int main()
{
int diameter = 0;
int height = 0;
double rate = 0;
char repeat = 'y';
int obj_num = 0;
displayGraphics();
obj_num = drawRect(0,0,50,400);
setColor(obj_num,200,200,200);
obj_num = drawRect(0,400,640,79);
setColor(obj_num,71,35,35);
obj_num = drawLine(50,50,150,50,5);
setColor(obj_num,80,80,80);
displayBMP("faucet.bmp",150,12);
do
{
do
{
cout << "Enter the diamater of the cylinder <in inches > 0 but <= 300: ";
cin >> diameter;
if((diameter<0) || (diameter>300))
{
cout << "Incorrect diamater entered; value must be between 1 and 300" << endl;
}
}while((diameter<0) || (diameter>300));
do
{
cout << "Enter the height of the cylinder <in inches > 0 but <= 325: ";
cin >> height;
if((height<0) || (height>325))
{
cout << "Incorrect height entered; value must be between 1 and 325" << endl;
}
}while((height<0) || (height>325));
do
{
cout << "Enter the facet water's rate: <gallons/minute> ";
cin >> rate;
if((rate<0) || (rate>100))
{
cout << "Incorrect rate entered; value must be between 1 and 100" << endl;
}
}while((rate<0) || (rate>100));
//I need to draw the lines here. The graphics window has a faucet that is supposed to fill
//up a cylinder made out of 3 lines. I don't know how to make the lines vary from the users
//input since lines are hard coded with points and all i am receiving is the width for the
//bottom line and the height for the left and right lines.
cout << "Repeat program? (y/n): ";
cin >> repeat;
clearGraphics();
}while ( (repeat == 'y') || (repeat == 'Y') );
return 0;
}
Here is a screenshot for reference:
