Factorial number?

A Factorial is a function that multiplies a number by every number.

For Example:- 

0!=1

1!=1

2!=2*1=2

31=3*2*1=6

4!=4*3*2*1=24

5!=5*4*3*2*1=120

Formula :- n!=n*(n-1)* ....*1

Factorial of the number

#include <stdio.h>
int main()
{
	int n,i,f=1;
	printf("\nEnter the value of n:");
	
        scanf("%d",&n); 
	
	for(i=1;i<=n;i++)
	f=f*i;         
	printf("\nFactorial =%d",f);
}

C Program to check whether a number is palindrome or not| E-studyblog|

C Program to check whether a number is palindrome or not| E-studyblog|

What is palindrome number ?

An Integer is said to be palindrome if the reverse number remains the  same of that given number.
Example: 1001 is a palindrome number
                1234 is not a palindrome number

C Program to check whether a number is palindrome or not:

#include<stdio.h>
int main(){
	int n,s=0;
	printf("\nEnter the Integers:");
	scanf("%d",&n);
	int k=n;
	while(n>0)
	{

		int d=n%10;
		s=(s*10)+d;
		n=n/10;
		
	}
       //if k and s are equal
	if(k==s)
	printf("\nThe number is palindrome number:");
	else
	printf("\nThe number is not palindrome number:");
	
	return 0;
	
}
