Example Program For Reverse Number In C Programming

/* Example Program For Reverse Number In C Programming Language */

// Header Files
#include<stdio.h>
#include<conio.h>

//Main Function

int main()
{
  //Varibale Declaration
  long int n,n1,reverse=0;

  printf("Enter the Number:");
  scanf("%ld",&n);

  while(n!=0)
  {
    n1=n%10;
    reverse=reverse*10+n1;
    n=n/10;
  }
  printf("Reverse Number Is :%ld",reverse);
  // Wait For Output Screen
  getch();

  //Main Function return Statement
  return 0;
}

Sample Output:

Enter the Number:78965

Reverse Number Is :56987

How It Works

This C program demonstrates Reverse Number. It first reads the required values as input, then walks through the data with a loop to compute the result, and finally prints the output shown in the Sample Output above.

1. Declare the variables that hold the program’s data.
2. Read the input values that the program will work with.
3. Iterate over the data using a loop to apply the logic.
4. Print the final result to the console so you can compare it with the sample output.

Try changing the input values and re-running the program to see how the output changes — this is the fastest way to understand how the logic behaves.
