In this post, we will write a **C++ program to find out whether the given number is prime or not**.

## C++ program to find out given number is prime or not.

```
#include<iostream>
#include<conio.h>
int main()
{
system("cls");
int i,n,count;
std::cout<<"Enter any number = ";
std::cin>>n;
count = 0;
i = 1;
do
{
if(n%i == 0)
count = count + 1;
i++;
}
while (i<=n);
if(count == 2)
std::cout<<"The number is prime ";
else
std::cout<<"The number is not prime ";
getch();
return 0;
}
```
