Validation Of Variables

i dont know if I'm in the right thread if some1 can help me on this please:

The program should display an Invalid Input if more than 5 variables are entered, how do I do this :

Note that a, b and c must be integers

example the equation is a + b = c.

If the user enters a + b = c + d the program should display an invalid input.

#include <iostream>
#include <string>
#include <iomanip>
using namespace std;

int main()
{
int var1, var2;
int result;
int compresult;

string op, eq ;
cout << "Please key in your equation : ";

cin >> var1 >> op >> var2 >> eq >> result;


if (cin.fail())
{
cout << "Invalid Input\n";
}
