I am needing help figuring out how to get this program to function correctly. The program is developed in order for a user to type in any number and it will tell if the number is prime or not. This works, however, I cannot figure out how to get it to say 2 is prime, and 9 is not prime. It also says 49 is prime and it is not. If anyone could help me with this I would greatly appreciate it!

```
//This program uses a function that returns true or false.
#include <iostream>
using namespace std;
//Function prototype
bool isPrime (int);
int main()
{
int val; //Get a number from the user.
cout<<"Enter a positive number and I will tell you ";
cout<<"if is a prime number or not: ";
cin>>val; //Indicate whether it is prime or not.
if (isPrime(val))
cout<<val<<" is a prime number.\n";
else
cout<<val<<" is not a prime number.\n";
return 0;
} //**********************************************************
//Definition of function isPrime. This function accepts an *
//integer arguement and tests it to be prime or not. The *
//function true if the arguement is prime or false if the *
//arguement is not. The return value is a bool. *
//**********************************************************
bool isPrime
(int number)
{
bool status;
{
int input = 2;
double root = sqrt((double)(number));
if(number%input==0)
return false;
input++;while(input<root)
{
if(number%input==0)
return false;input+=input+2;
}return true;
}
return status;
}
```
