need help with error generated in slot machine

[bananaland]

Hiya,

I'm new to C++, and working on Windows 7 with Visual Studio Express 2012. I've pasted my code below. The winnings variable that is declared and defined in the main generates an error within the method that calls it ( the void display method at the bottom ). Any pointers? I hit a wall with this two days ago and have been ineffectually flailing around since. Thanks in advance.

#include <ctime>
#include <iostream>
#include <sstream>
#include <string.h>
#include <random>

using namespace std;




class TripleString
{

   string string1, string2, string3;

public:
   static const int MAX_LEN=20;
   TripleString();

   bool validString( string str );
   void set(string str1, string str2, string str3);
   string get(int strPosition);
};

TripleString::TripleString()
{
string1="";
string2="";
string3="";
}


bool TripleString::validString(string str)
{
   if (str.length()<=MAX_LEN)
      return true;

   return false;
}

void TripleString::set(string str1, string str2, string str3)
{
   if(validString(str1))
   {
      string1=str1;
   }
   if(validString(str2))
   {
      string2=str2;
   }
   if(validString(str3))
   {
   string3=str3;
   }
}

string TripleString::get(int pos)
{
  if(pos==1)
  {
     return string1;
  }
  if(pos==2)
  {
     return string2;
  }
  if(pos==3)
  {
     return string3;
  }
}


int getBet();

TripleString pull();

string randString();

int getPayMultiplier (TripleString thePull);

Here are the errors that are generated:

srand((unsigned)time(0));

srand expects an unsigned int as its argument, but the time(NULL) return type is a time_t object. cast the object to unsigned.

int getPayMultiplier (TripleString thePull)
{
   ...
} <-- needs a closing brace

void display (TripleString thePull, int winnings ); <-- semi-colon
{
   ...
   } <-- one extra closing brace
}

If the code you've posted isn't a typo, then the other two are syntax errors. getPayMultiplie r() lacks a closing brace. add a closing brace at the end of the code block.

display() has a rogue semi-colon at the end of its parameter list; it also has one too many braces - remove the semi and remove one closing brace.
