## C++ Program to Find Sum of Square of n Natural Numbers

This C++ program will find the sum of squares of n natural numbers. Starting from 1, 2, 3, etc are called natural numbers. For example: n = 3 Then, Sum =  12 + 22 + 32 = 14 Output: Enter any number: 50Sum=42925

## Palindrome Number in C++

Here you will get a C++ program to check whether a number is a palindrome or not. A number is a palindrome if it is equal to its reverse. For example, 121 is a palindrome because if we reverse the order of digits then the number so obtained is equal to the original number. Output: …

## Find Divisors of a Number C++

Below is the C++ program to find all the divisors of a number. A divisor is a number that divides another number completely. For example, D is the divisor of N if N%D=0. Output: Enter the number: 6Divisors of 6 are 1 2 3 6

## Sum of Digits of a Number in C++

Below I have shared a C++ program to find the sum of the digits of a number. For example, given number is 238 then the sum of digits will be 13. I am using very simple logic. If we find the mod of any number by 10 then the result is the last digit of …

## C++ Program to Find Sum of First n Natural Numbers

Here I have given C++ program to find the sum of the first n natural numbers. First of all, I am reading the value of n and then calculating the sum using for loop. If you have any doubts related to the program then feel free to ask in the comment section. C++ Program to …

## C++ Program to Find Factorial of a Number

Here I have shared the factorial program in C++. A Factorial is the product of a number and all the numbers below it. For example, the factorial of 4! = 4 × 3 × 2 × 1 = 24. #include<iostream> using namespace std; int main() { unsigned long i,fac,n; cout<<“Enter number: “; cin>>n; for(i=1,fac=1;i<=n;++i) { …
