Hello everyone,

I'm attempting to write a program for an assignment dealing with a class in C++. As you may have guessed, classes are new to me. And it seems as though that is what is giving me these errors:

1>c:...main.cpp(90) : error C2228: left of '.number' must have class/struct/union

1>c:...main.cpp(91) : error C2228: left of '.sieve' must have class/struct/union

1>c:...\main.cpp(92) : error C2228: left of '.print_primes' must have class/struct/union

I have searched for an answer, but it seems as though this error pops up if there is anything at all wrong with the class. I cannot figure out what is wrong with mine. Thanks for any help!!

Here is my code:

```
#include <iostream>
using namespace std;
class Prime_Finder {
public:
Prime_Finder();
~Prime_Finder();
void number();
void print_primes();
//void get_number();
private:
void sieve();
int *IntArray;
int Input_Number;
protected:
};
Prime_Finder::Prime_Finder()
{
IntArray = new int[Input_Number];
}
Prime_Finder::~Prime_Finder()
{
}
void Prime_Finder::number()
{
cout<<"Please input a value: ";
cin>>Input_Number;
}
/*void get_number()
{
return(Input_Number);
}
*/
void Prime_Finder::sieve()
{
for ( int index=2; index <= Input_Number; index++ )
{
if ( IntArray[index] == 1 )
for ( int i = index+1; i <= Input_Number; i++ )
if ( i % index == 0 )
IntArray[i]=0;
}
}
void Prime_Finder::print_primes()
{
int count=1;
for( int index = 2; index <=Input_Number; index++)
if ( IntArray[index] == 1 )
{
count++;
if ( count % 10 == 0 )
cout<<index<< endl;
else
cout<< index << " ";
}
cout << endl;
}
int main()
{
Prime_Finder findprimes();
findprimes.number();
findprimes.sieve();
findprimes.print_primes();
}
```
