Question

(C Language) Write a program to display a histogram based on a number entered by the user. A histogram is a graphical representation of a number (in our case, using the asterisk character). On the same line after displaying the histogram, display the number. The entire program will repeat until the user enters zero or a negative number. Before the program ends, display "Bye...".

The program will ask the user to enter a non-zero positive number. Using a while loop, validate that the number is not greater than 40, and if so, re-ask for the number. Put the entire program into a sentinel-controlled loop so that the user can enter either zero (0) or a negative number to end the program.

Create constants for 1 (the minimum number for the histogram), and 40 (the maximum number for the histogram), and use these constants in the prompts, the validation condition and error message, and the sentinel-controlled loop and the histogram loop.

Hints:

Validation messages are indented 3 spaces
You can use either a pre-test loop (with the initial prompt outside the loop, and the re-prompt at the end of the loop) or a post-test loop (with the prompt inside the loop, and a decision to print the histogram also inside to loop).
Coded the histogram using a for loop (although any type of loop could be used)
Example Run:

(bold type is what is entered by the user)

Enter a non-zero positive number less than 40: 5
***** 5

Enter another non-zero positive number less than 40: 48
The number entered was greater than 40.
Please re-enter: 8
******** 8

Enter another non-zero positive number less than 40: -1

Bye...

The example run shows EXACTLY how your program input and output will look.

Explanation:

Note: Could you plz go through this code and let me know if u need any changes in this.Thank You

=================================

#include <stdio.h>

#include <stdlib.h>

#include <ctype.h>

#include <string.h>

int main() {

  //Declaring constants

const int MIN=1;

  const int MAX=40;

 

  //Declaring variables

  int num,i;

      printf("Enter a non-zero positive number less than 40: ");  

     

     

/* This while loop continues to execute

* until the user enters a number <=0

*/

  while(1)

  {

      scanf("%d",&num);

      if(num<=0)

      {

          break;

      }

      else if(num>40)

      {

      printf("The number entered was greater than %d.\n",MAX);

          printf("Please re-enter: ");

      }

      else

      {

          for(i=0;i<num;i++)

          {

              printf("*");

          }

          printf("%d\n",num);

          printf("Enter another non-zero positive number less than 40: ");

      }

         

  }

 

  printf("bye...");

  return 0;

 

}

================================

output:

Enter a non-zero positive number less than 40:5

*****5

Enter another non zero positive number less than 40: 48

The number entered was greater than 40.

please Re-enter: 8

********8

Enter another non zero positive number less than 40: 1

bye...
