input a number check number is prime number or not while loop (computer program)
Answers
Answer:
Before going to the program for Prime Number or Not first let us understand what is a Prime Number?
Prime Number:
A Prime Number is a number greater than 1 and which is only divisible by 1 and the number itself.
For example,
17 is a Prime Number, because 17 is not divisible by any number other than 1 and 17.
To find whether a Number is Prime Number or Not it is enough to check whether ‘n’ is divisible by any number between 2 and √n. If it is divisible then ‘n’ is not a Prime Number otherwise it is a Prime Number.
Explanation:
Write C++ program to check whether a number is Prime number or not using while loop
#include <math.h>
{
int num, i, f;
//Reading a number from user.
cout<<"Enter any number:";
cin>>num;
f = 0;
i = 2;
