Thread: problem with functions

Hello,

I am trying to make a program that prints out a square with width defined by the user. The program compiles, and asks user for width, but after that nothing happens. What am I doing wrong?

Code:

#include<stdio.h>

/*Prompts user to enter width*/
int getwidth(int width);

/*Prints out a square*/
char printsquare (void);

int
main(void)
{
        int width;
        char printsquare;

        width = getwidth(width);

        printsquare;

        return(0);

}

/*Function that prompts user to enter width */

        int getwidth (int width)
{
        printf("Enter width for the house, it must be odd number bigger than 5> ");
        scanf("%d", &width);
        return width;
}

/*Function that prints out a square */
        
        char printsquare(void)
        
{
/* prints out top of the square */
 
        int width;

        int count = 0;
        while(count < width)
        {
                printf("%c", '*');
                count=count+1;
        }
        printf("\n");


/* prints out left and right walls of the square*/
        
        int count1 = 0;
        while(count1 < width-2)   
        {
                printf("%c", '*');
          int count2 = 0;
          while(count2 < width-2) {
                printf("%c", ' ');
          count2=count2+1;
                }
                printf("%c", '*');
                printf("\n");
                count1=count1+1;
        }
        
/*prints out bottom of the square*/

        int count3 = 0;
        while(count3 < width)
        {
                printf("%c", '*');
                count3=count3+1;
        }
        printf("\n");
          
                
}

I can't get what's wrong with this code. Do you see what's wrong with it?

what do you mean by "ambiguous character in main"?

hmm, i wish i knew which one you are talking about.

i give up.
