Passing Strings

[Tarkle]

I have this code:

#include <iostream>
#include <cstdlib>
#include <ctime>
#include <iomanip>
#include <stdio.h>
#include <string.h>
using namespace std;

bool validateSelection(string); //Prototype

int main()
{
  int f;
  string p = "QTR";
  f = validateSelection(p);
  if(f == 1){
  cout << "Works";
  }
}

bool validateSelection(string g)
{
  if(g[0] == "Q") //error forbidding comparison between pointer and integer
      {
        return true;
      }
}

What this code is supposed to do is check for the first letter of a string.

I'm new to pointers and how strings actually work. I have tried a mess of things and made bigger messes I didn't understand.

Thanks for any help in advance!

g[0] gives you a character. "Q" is a string. Use single quotes 'Q' if you want a character.

Oh my, it was that simple. It works fine now. I was starting to use strcmp and all these things I didn't understand.

Thank you Peter.
