Thread: Problem with while loop (not looping back despite test being true)

try checking your brackets. having that many you need to be sure to try and keep track of them and stuff

Code:

     if (result == number)
    {
        printf("%d's an armstrong number.\n", number);
    }
    else
    {
        printf("%d is not an armstrong number.\n", number);
    }
    if (printf("Wanna check again?(y or n) \n"))
    {
        if (getchar() == 121)
        {
        } 
    else
        {    // right there shuts your loop down
            // put a printf in here to see for sure
             printf("in just before setting test to false\n");
            test = false; 
        }
    }
  }

your logic is a little off too. Now that I look at it closer.

Code:

     if (result == number)
    {
        printf("%d's an armstrong number.\n", number);
    }
    else
    {
        printf("%d is not an armstrong number.\n", number);
    } // why is that in an if statement and no means to check what it is looking for?
    if (printf("Wanna check again?(y or n) \n"))
    {
        if (getchar() == 121)
        {
        } 
    else
        {    // right there shuts your loop down
            // put a printf in here to see for sure
             printf("in just before setting test to false\n");
            test = false; 
        }
    }
  }

still needs work, but I mostly fixed some of your logic

Code:

//Programming in C 
 
 
/*
* checking armstrong for n digits
*/
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
#include <stdbool.h>

#include <ctype.h> // tolower


 
 
int main(int argc, char const *argv[])
{  
  int number, originalNumber, remainder, result = 0, n = 0;
  char what  = '\0'; // set to null 
 
  system("clear");
 
 
  bool test = true;
 
 
  while (test)
  {
        printf("Enter an integer: \n-> ");
        scanf("%d", &number);
        originalNumber = number;
        
    while (originalNumber != 0)
    {
        originalNumber /= 10;
        printf("1. loop orginal Number %d\n", originalNumber);
        ++n;
    }
    originalNumber = number;
    printf("2. loop orginal Number %d\n", originalNumber);
    while (originalNumber != 0)
    {
        remainder = originalNumber%10;
        result += pow(remainder, n);
        originalNumber /= 10;
        printf("3. loop orginal Number %d\n"
                "result = %d\n"
                "number %d\n", originalNumber, result,number);
    }
    if (result == number)
    {
        printf("%d's an armstrong number.\n", number);
    }
    else
    {
        printf("%d is not an armstrong number.\n"
                "would you like to try another one? y/n\n", number);
                what = getchar();
    }
    
    if (tolower(what) == 'n')
        test = false;
        
        
        /*
    {
        if (getchar() == 121)
        {
        } 
    else
        {    printf("in just before setting test to false\n");
            test = false;
        }
    }
    */
  } 
  getchar();
  return 0;
}

keep them printf in there then run it a few times to see what is really going on. Needs more work because you forgot something else as well when using loops and the same vars repeatedly. After you get it fixed try to make it look pretty.
