What a C program that will accept an integer N as input if and only if that integer N lies within 0-9999 Then it will produce the summation of its digits and lastly prints the integer as well as the?

Answer 1

9999

Answer 2

#include<stdio.h>

main()

{

int N,num,sum=0;

do

{

printf("Enter a number:\n");

scanf("%d",&N);

if((N>9999)(N<0))

{

printf("Wrong Number\n");

}

while((N>9999))(N<0));

num=N;

while(N>0)

{

sum=sum+N%10;

N=N/10;

}

printf("Sum of digits of the number%d is%d",N,sum);

}

}

Answer 3

I don't have a C compiler, I used to, not anymore. I know this is not what you want. But I have coded it in C#. May be you can translate to C. I will keep looking for a C compiler and update the answer if successful. In the meantime, see if you can use the following.

using System;

using System.Collections.Generic;

using System.Linq;

namespace SumDigits

{

class Program

{

static void Main(string[] args)

{

int i;

int ierr;

int isumofdigits;// To store sum of digits

string strInput;// Define input string

string strOutput;// Define output string

string str4Digits;// Define string to hold 4 digits

do

{

ierr = 0;

strInput = "";

Console.WriteLine("Enter a number between 0 and 9999, / to Exit");// Prompt the user

strInput = Console.ReadLine();//Read input from keyboard

if (strInput.Length != 0)// Check if not zero length

{

if (strInput.Substring(0, 1) != "/") // Check if not "/"

{

if (strInput.Length > 4)// Check if more than 4 characters

str4Digits = strInput.Substring(0, 4);// Get utmost 4 characters

else

str4Digits = strInput.Substring(0, strInput.Length);// Else get chars entered

for (i = 0; i < str4Digits.Length; i++)// Do this loop for length of 4 digit buffer

{

char ch;// Define temporary character

ch = Convert.ToChar(str4Digits.Substring(i, 1));// Convert character from 4 digit string to chars

if (!(char.IsDigit(ch)))// Check if character is a digit (0 -9)

{

Console.WriteLine("One or more digits entered is not numeric");// Error message

ierr = 1;

break;

}

}

if (ierr "/")// User entered "/"

{

Console.WriteLine("Thanks for using the program");// Display parting message

Console.WriteLine("Press the Enter Key to End Program");// Display prompt message

Console.ReadLine();// Wait for user acknowledgement

break;

}

}

else//User entered nothing, continue

{

continue;

}

} while (true);

}

}

}
