Hi, I am currently newbie in C++, I just learned it for around 2 weeks,

My question is when I put the number, it shows if it's a prime number or not.

The only problem when I put 2 and 3, it supposed to be prime numbers, but the fact that it is not.

Here is my code

#include <iostream>

#include <math.h>

#include <cstdlib>

using namespace std;

#define TRUE 1;

#define FALSE 0;

void getNumber(int*);

int isPrime(int*);

int main()

{

int number;

getNumber(&number);

if (isPrime(&number))

cout << "\n" << number << " is a prime number\n";

else

cout << "\n" << number << " is a not prime number\n";

return 0;

}

void getNumber(int *number)

{

// use pointers as parameter, not references

cout << "Please enter a positive number ";

cin >> *number;

if (!cin.good())

{

cout << "Invalid number entered\n";

exit(1);

}

}

int isPrime(int *number)

{

int count, s, i;

/* Every even number is not prime */

if (*number % 2 == 0 || *number % 3 == 0 || (*number < 4 && *number > 1) return FALSE;

/* check every odd number up to the square root of the number */

s = sqrt(*number);

for (count=3; count<=s; count+=2);

{

if (*number % count == 0) return FALSE;

}

return TRUE;

}

I think the green part need some fixing, can someone pointed out what is my mistakes? THank youu :)
