C program to check whether the number is pronic number or heteromecic number or not| Rectangular number in c|E-studyblog

In this Article, you will learn how to check whether the number is pronic number or heteromecic number or not. A Pronic Number is a number which is the product of two consecutive number ,i.e., a number of the form n*(n+1).It is also known as rectangular number,heteromecic number or oblong number).

C program to check whether the number is pronic number or heteromecic number or not|

Pronic Number |Heteromecic Number | Rectangular Number:

A Pronic Number is a number which is the product of two consecutive number ,i.e., a number of the form n*(n+1).It is also known as rectangular number ,heteromecic number or oblong number .

Pronic number (n)= x*(x+1)

For Example: 6 is a pronic number

2*3=6

2*(2+1)=6

Some Pronic numbers are 0, 2, 6, 12, 20, 30, 42, 56, 72, 90, 110, 132, 156, 182, 210, 240, 272, 306, 342, 380, 420, 462 … etc

C Program to find Factorial of the number using For -Loop|E-studyblog|

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);

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;
