Problems with functions and for loops

[slava]

Hello,
I''m having problems with a program which involves functions.
The user is supposed to input the letter he wants printed out either I or F or Quit ,Q. He can start over with another letter after printing one out.
They can be between 5 and 11 stars in height but the width is always the same. Also the letter must be only an uneven number in height say 5, 7, 9, or 11.
The thing is the letters are always 5 in height and sometimes the letter F doesn't print out correctly if you start over after printing I.
I'm also supposed to use embedded for loops for the letters which is not what I've done.
Can anyone help me out?

[CODE]

#include <stdio.h>
#include <ctype.h>
 
 
          // shows user what choices he has
 void showMenu()   { 
        char  I, F, Q;
        
        printf("\n    Menu\n");
        printf(" I : Letter I\n");
        printf(" F : Letter F\n");
        printf(" Q : Quit\n");
        printf(" Enter your choice:");
        }
        // reads choice of the user and validates it
        char readChoice( ) 
    
       { 
             char Choice;
         Choice=toupper(getche());
         
       }
       
       // reads height of letters wanted and validates it
       int readHeight(int min, int max )
       
    {  int height;
        printf("\n\nHeight of letter must be between 5 and 11\nEnter your height: ");
        scanf(" %d", &height);
         return 0; }
   
    // drawI : draws the letter I
    void drawI( int height)   {
         int i;
          
         printf("*****\n");
         for( i=0; i-2<=height;i++){
         printf("  *  \n");
         
         }
         printf("*****");
         
         getch();
        } 

   // drawF : draws the letter F
    void drawF( int height)   { 
         int i;
        printf("*****\n");
        printf("*\n");
        printf("*****\n");
         for (i=1; i-2<=height;i++) 
        printf("*\n", i);
        scanf("%d", &i);
           }

   // systemPause 
    void Pause( )
    {   
        printf("\n Press any key to continue");
        getch();
    } // end Pause 
    
  //main program
   int main()
   { 
     char  Choice;                  // users' choice
     int   height;                // height of the letter
     
     do
     {
        showMenu();
        Choice = readChoice();
        if ( Choice != 'Q' )
        {
             height = readHeight( 5, 11);
             switch (Choice)
             {
                case 'I' : drawI(height);   break;
                case 'F' : drawF(height);   break;
              }// end switch
        }  // end if 
    }// end while
    while (Choice != 'Q');
    
    Pause();
    

   } // end main

// reads height of letters wanted and validates it 
       int readHeight(int min, int max ) 
        
    {  int height; 
        printf("\n\nHeight of letter must be between 5 and 11\nEnter your height: "); 
        scanf(" %d", &height); 
         return 0; }

readHeight() returns 0 instead of the height input by the user so its puzzling that the program will even print 5 stars ie the minimum height.
