Please do the coding in C language!

Demo: Here is the solution for Homework# 4.6. It is written as a procedural program. int counter 1. counter 2 char hChar1 vChar1 int 1, wd1 char answer y'; print f("In Using for -loop and user values continuously "); while (answer y') printf("VnPlease enter height of a box: scanf("%d &ht1;); printf("VnPlease enter width of a box: scanf("%d &wd1;); //you first need to flush the buffer, which still has In' character due to pressing enter while (getchar In printf ("InPlease enter the vertical charcters to draw box scanf ("%c", &vChar1;); //don't forget to remove the new line character after //reading just a charcter in above code while (getchar() printf("InPlease enter the horizontal charcters to draw box: scanf ("%c", &hChar1;); printf ("In"); for (counter1 1; counter 1 Wd1 counter 1++) printf( "%c hChar1); printf ("In"); for (counter 1; counter 1 ht1 2; counter 1++)

Explanation / Answer

#include <stdio.h>

// A.
void drawHorizontalLine(int wd1, char hChar)
{
   int counter1;
   for(counter1 = 1; counter1 <= wd1; counter1++)
   {
           printf("%c",hChar);
   }
}

// B.

void drawVerticalLine(int ht, int wd, char vChar)
{
   int counter1, counter2;
   for(counter1 = 1; counter1 <= ht-2; counter1++)
   {
           printf("%c",vChar);
           for(counter2 = 1; counter2 <= wd-2; counter2++)
               printf(" ");
           printf("%c ",vChar);
   }  
}

// C.

void drawBox(int ht, int wd, char vChar, char hChar)
{
   printf(" ");  
      
   drawHorizontalLine(wd, hChar);

   printf(" ");  

   drawVerticalLine(ht, wd, vChar);  

   drawHorizontalLine(wd, hChar);

   printf(" ");
}

int main(int argc, char const *argv[])
{
   char hChar1, vChar1;
   int ht1, wd1;
   char answer = 'y';

   printf(" Using for-loop and user values, continuosly: ");

   while( answer == 'y' )
   {
       printf(" Please enter height of box: ");
       scanf("%d", &ht1);
       printf(" Please enter width of box: ");
       scanf("%d", &wd1);

       while(getchar() != ' ');

       printf(" Please enter the vertical characters to draw box: ");
       scanf("%c", &vChar1);

       while(getchar() != ' ');

       printf(" Please enter the horizontal characters to draw box: ");
       scanf("%c", &hChar1);

       // D.
       drawBox(ht1, wd1, vChar1, hChar1);

       while(getchar() != ' ');

       printf("Continue? Type y for yes: ");
       scanf("%c",&answer);
   }
   return 0;
}
