    Code:
    #include <stdio.h>
    
    int main(void)
    {
    	int i = 0;
    
    	int width = 6;
    	/* start of line */
    	putchar('*');
    
    	for(i = 1; i< width-1; i++)
    		putchar(' ' );
    
    	putchar('*');
    	putchar('\n');
    
    	/* end of line */
    	return 0;
    }
    try to put the code between comments into loop
    The first 90% of a project takes 90% of the time,
    the last 10% takes the other 90% of the time.

        18
        19  if (width == 4)
        20  printf("****/n");
        21  else if (width == 5)
        22  printf("*****/n");
        23  else if (width == 6)
        24  printf("******/n");
        25  else if (width == 7)
        26  printf("*******/n");
        27  else if (width == 8)
        28  printf("********/n");
        29  else if (width == 9)
        30  printf("*********/n");
        31  else if (width == 10)
        32  printf("**********/n");
        33  else if (width == 11)
        34  printf("***********/n");
    Dude, copy and paste.

    Sorry, I couldn't help myself.

    The outer loop should be the height. The inner loop will be the width, controlling each horizontal line printing.

    Code:
    int hgt, height, wdt, width;
    
    for(hgt = 0; hgt < height; hgt++)   {
       for(wdt = 0; wdt < width - 2; wdt++)   {
          if(wdt == 0 || wdt == width- 1)              //the outer border
             printf("*");                                          
          if(hgt == 0)                                //first line is all stars
             printf("*");
          else
             printf(" ");                             //inner spaces 
       }
    }
    The above is just off the cuff, and totally untested, should give you some idea's

    first if is missing else I think - to avoid printing * twice for the conors

    But easier way - to take the first line completely from the loop and make loop on heght starting with the second line
    The first 90% of a project takes 90% of the time,
    the last 10% takes the other 90% of the time.
