What'd I do this time ...

Ok so I was going to make a conversion program which, when executed gave you an option of 1 or 2 (so original I know) so I had a integer (int) which checked which one you typed (1||2) but whenever I have it run if I type a character like "a" it converts it to a number :(
by the way I'm going to make functions for conversion later.

#include <cstdlib>
#include <iostream>

using namespace std;

int main()
{
    string choice;
    cout << "Type 1 to convert Fahrenheit to Celsius\n";
    cout << "Type 2 to convert Celsius to Fahrenheit\n";
    cin >> choice;
    if (choice != ("1" || "2")){
       cout << "Please enter a valid number";
       cin.get();
    }else if (choice == "1"){
       //Farenheit to Celsius
    }else if (choice == "2"){
       //Celsius to Fahrenheit
    }      
          
    cin.get();
    return 0;
}



btw again this is what meh debugger outputs
expected primary-expression before '=' token

       //Celsius to Fahrenheit
       cout << "C to F";
       cin.get();

    cin.get();
    return 0;
}

One of my programming teachers called what you're doing "scratching your left ear with your right hand".
