Menu driven drawing program

Mike Gustafson · #1 27-Sep-2006, 10:35

Hello again,

If I make it though this class it will be a miricle. Now I to do this and can't even get started text book not much help so here it goes, I really need help with this one.

Write a menu driven appication that displays the following menu and draws shapes. Your program should run continuosly until the users selects to quit the program. In addition to the following outputs, turn in the psuedocode and a flow chart of your program.
1.) Draw a Diamond
2.) Draw a Wine Glass
3.) Draw a Triangle
4.) Quit the program.
Am I wrong to think this is difficult if you have never programed what so ever and this is my first programming course.
Any help I will be very happy to get.
Thank you

I finally got it does it look ok? I know a real programmer would do it much better and more simple but it works. Did I waste a lot of printf lines?

CPP / C++ / C Code:

/* Project 2
	Menu driven drawing program */


#include <stdio.h>

/* function main begins program execution */


int main() /* start program */
{
	int num; /* number of shape you want to draw */

	printf(" Enter a number to draw \n 1 Diamond\n 2 Wine Glass\n 3 Triangle\n 4 Quit\n ");
	scanf("%d",&num);
		if ( num <=3 ) /* a choosen shape will draw */
		{
			do 
			   
			{
				if (num == 1) /* a diamond will be drawn */
				{

					printf( "    *  \n");
					printf( "   ***  \n");
					printf( "  ***** \n");
					printf( " *******\n");
					printf( "*********\n");
					printf( " *******\n");
					printf( "  ***** \n");
					printf( "   ***  \n");
					printf( "    *  \n");
				}
	
						else 
								if (num == 2) /* a wine glass will be drawn */
								{			 
									printf("**********\n");
									printf( " *******\n");
									printf( "  ***** \n");
									printf( "   ***  \n");
									printf( "    *  \n");
									printf( "   ***  \n");
									printf( "  ***** \n");
									printf( " *******\n");

							    }
						else 
				                  if (num == 3) /* a triangle will be drawn */
							      {			 
									printf("***********\n");
									printf("**********\n");
									printf("*********\n");
									printf("*******\n");
									printf("******\n");
									printf("*****\n");
									printf("****\n");
									printf("***\n");
									printf("**\n");
									printf("*\n");
								  }

			printf(" Enter a number to draw \n 1 Diamond\n 2 Wine Glass\n 3 Triangle\n 4 Quit\n ");
			scanf("%d",&num);

			}while (num<=3); /* continue to draw shapes while number <=3 */
        
		} /* end if */
	
	return 0; /* indicate program ended successfully */

}		/* end function main */

Yes. Use loops.

is so hard to understand? Every post you make with code has to be modified. Maybe you need to review the Guidelines again.

Yes I didn't post it right sorry. Well I did it all wrong loops like you say is the way I'm supposed to do it. This is sort of what I have to get the program to draw except shapes are different and bigger. I can't figure out how you make it loop to print ***********'s in a certain order and placement.

You have multiple lines. Therefore a loop is in order to go from line to line -- at least from top to line with the most *'s. There's loop #1.

Count the Spaces on the first line of your printf() attempt, then the second line. Is there a correlation between the numbers? Keep going for each line and compare each line for spaces. See a pattern? Loop #2 within loop #1 to print spaces.

Now do exactly the same for the *'s. Loop #3 within loop #1, but after loop #2 to print *'s.

There's your top triangle.

Use [code][/code] tags to display your pattern:

Code:

   *
  ***
 *****
********

And this info will help you with your formatting.
