Thread: suffix help.

Hi,
I'm doing this little program, and i need help.
well, I want to make the calculator program where you can add more than 2 numbers.

example:
Enter your 1st number:
Enter your 2nd number you want to add to 1st number:

the answer is:
do you want to continue? [y]/[n]?
If yes:
Enter your __th/nd/rd number:

Here is where i need help:

how do i program it so that when a user enters yes, it will display the suffix after it, and the number increases after each loop, till termination.
like for the first time, it will be:
Enter your 3rd number:
2nd time it will be:
Enter your 4th number
Enter your 5th number
etc etc.

ive tried doing it, but... i get an error message saying:
Linker error undefined reference to WinMain@16

here's what i've tried:

Code:

#include <iostream>
#include <stdlib.h>
#include <cmath>

using namespace std;


// Variables:
double number1, number2; //variable declared for basic functions
double answer = 0; // variable declared for basic functions and initialised
double memory; // variable declared for memory functions
double value; // variable declared for memory functions
double numba; // variables declared for memory functions
double binary; // variables declared for binary functions

int numberX; 
int valueX = 3;

char additional; //variable declared for loop [basic functions]
char clear2; // variable declared for loop [memory function]

string suffix;

//function for addition
//basic 
void addition() //function start for addition
{
//basic 
   system("cls"); //clears screen
      cout << "*------------*\n";
      cout << "|  Addition  |\n";
      cout << "*------------*\n";
      cout << "Please Enter 1st Value: ";
      cin  >> number1;
      cout << "Please Enter 2nd Value: ";
      cin  >> number2;
      cout << "The Answer is: "
      << number1 << " + " <<number2 << " = " << number1 + number2 <<".\n";
      answer = number1 + number2;
		  
//adding additional numbers
do { //adding additional number loop begins
   cout << "\n\n";
   cout << "Do you want to continue?[y/n]: ";
   cin  >> additional;

   switch(additional) { //switch begins
  		  
//If user inputs [y]
      case 'y':
      if (valueX%10 == 1)
         suffix = "st";
      else if (valueX%10 == 2)
         suffix = "nd";
      else if (valueX%10 == 3)
         suffix = "rd";
      else 
         suffix = "th";
      cout <<"Enter the" << valueX << suffix << "to add onto the answer.";
      cin >> numberX;
      cout << "The Answer is: "
      << answer << " + " << numberX << " = " << answer + numberX <<".\n"; 
      answer = answer + numberX;
      break;
  	 

    
//If user inputs [n]
      case 'n':
      system("PAUSE");
      cout << "\n";
      break;
   
      default: //validation
      cout << "Uh-Oh...You typed something wrong..Please Try again. Thank You ^-^\n";
}}while (additional != 'n'); //loops till 'n' is entered
}

Make sure you are compiling as a console application and not a windows GUI. In dev-c++ go to "project options" and under the "general" tab you should see "type:" Change that to Win32 Console
