Box program almost completed need additional help

**Rukris** · 10-31-2011

Hello everyone, I am almost finished writing a box program based on the users input of the size of the box.

So far my program is

Code:

#include <stdio.h>

int
main(void)
{
int num;
int top;
int newtop;
int oside;
int obot;
int bot;
int side;

        printf("Enter the size of a box: "); /*takes input from user*/
        scanf("%d", &num);
top = 0;
side = 0;
bot = 0;
newtop = 0;
oside = 0;
obot = 0;

while (newtop != num) {
newtop++ ;
printf("*");

}
while (side != num) {
side++ ;
printf("*\n");

}
while(bot != num) {
bot++ ;
printf("*");

}

return 0;
}

A sample run of the program :

Code:

linux3[3]% ./a.out
Enter the size of a box: 5
******
*
*
*
*
*****
linux3[4]%

However to complete the project how would I go about printing a box like this

Any help would be appreciated ! Thank you in advance

It's best to print both sides of the box, at the same time, so change this:

Code:

while (side != num) {
   side++ ;
   printf("*\n");

}
sides2print = heightoftheBox-2;

//to something like this:
while(side!= sides2print) {
   if(side==0 || side equals num) 
      print *
   else
       print space ' ' char
    if(side equals widthOfTheBox) {
       print newline
       side++;
    }
}

If the user enter 3 x 3 box, the side loop will print one "row" only, since the other two rows are either the top or the bottom. So it's total height of the box, -2 equals side rows to print.

You increment the side variable, only when it has printed the * on the far right hand side of the box, and it has printed the newline.

Get that going and I'll help you with the diagonals. The above may be off a bit, but you'll get the idea.
