C and C++ Programs to Check Whether a Number is Strong Number or Not

This post contains C and C++ program to check whether a given number is Strong number or not. A strong number is a number for which the sum of factorials of its digits is equal to the number itself. The first one is C program to check whether the input number is a strong number or not. An example is 145. 1!+4!+5!=1+24+120=145 Therefore 145 is a strong number.

C Program:

#include<stdio.h>
long int factorial(int n)

C and C++ Programs for String Sorting

Here i am writing programs in c and c++ languages to sort a given number of strings. Sorting is carried out based on the ASCII values of the letters in the strings. The string comparing function strcmp() is used in the program. These programs sort a given set of strings in ascending order.To change it into descending order just replace > with < in comparison line. The comparison line in the code is marked by comment.

C Program:

#include<stdio.h>
#include<string.h>
#include<conio.h>
void main()
{

C and C++ programs to check whether a given number is Odd or even

C Program

void main()
{
int n;
printf("Enter an integer\n");
scanf("%d",&n);
if ( n%2 == 0 )
printf("Even");
else
printf("Odd");
}

C++ Program

#include<iostream.h>
void main()
{
int n;
cout<<"Enter an integer\n";
cin>>n;
if ( n%2 == 0 )
cout<<"\nEven";
