    need help with this code


    I'm new to c programming and need some help with this code

    I'm ask to write a program that reads in the side of a square and the prints that square out of asterisks. The program should work for squares of all side sizes between 1 and 20. For example, if the program reads a size of 4, it should print

    It then ask me to modify the program so that it prints a hollow square. For example if the program reads a size of 5, it should print

    *   *
    *   *
    *   *
    I was able to do the first part but don't know how to do the second part can any one help me

    below is the code for the first part:
    #include <stdio.h>
    #include <stdlib.h>
    int inputInteger(int, int);
    #define MININPUT 1
    #define MAXINPUT 20
    #define TRUE 1
    #define FALSE 0
    int main (void)
    int squareSize, column, row;
    squareSize = inputInteger(MININPUT, MAXINPUT);
    row = squareSize;
    while(row >= 1){
             column = 1;
             while(column <= squareSize){
    int inputInteger(int minInput,int maxInput){
       int reading;
       int validInput;
          printf("\nPlease enter the number of side of a square: ");
          validInput = scanf("%d", &reading);
                         printf("\nThis is not a valid entry\n");
          if((validInput == TRUE)&&((reading >maxInput)||(reading < minInput))){
               printf("Error, the number entered needs to be between %d to %d\n", minInput, maxInput);
               validInput = FALSE;
       return reading;

    Look at an empty box. What do you have? (Note: There's an exception for a size=1 box.)

    ***** <-- a top line
    *   * <-- a number of "hollow" lines
    *   *
    *   *
    ***** <-- a bottom line
    What is a hollow line?
    starting edge
    *   *
        ending edge
    Between the start and end edge, there are a number of spaces. Notice that the number of spaces is the same as the number of hollow lines.

    Hope is the first step on the road to disappointment.
