Beginners question about methods

[lucozade33]

Hi all! I am just taking my first steps into learning c++ for fun, but I can't seem to get some code working here...

a simple method I am using returns the error:

error C2601: 'Addition' : local function definitions are illegal
1> getline.cpp(11): this line contains a '{' which has not yet been matched

it seems to be refering to :

int Addition(int x, int y){
int useranswer;
useranswer = x + y;
return useranswer;
}

and as far as I can see the { is matched with } at the end, is it not?

can anyone help me with this, please?

the entire (unfinished) code is:

#include <iostream>
#include "conio.h"
#include <string>
using namespace std;

int Addition(int x, int y);
int Subtraction(int x, int y);
int Multiplication(int x, int y);


void main(){
int num1;
int num2;
string mathtype;
cout << "What do you want to do? add, subtract, or multiply? ";
getline(cin, mathtype);
cin.clear ();
cout << "You picked " << mathtype << endl;
cout << "Enter a number: ";
cin >> num1;
cout << "Enter another number: ";
cin >> num2;
if(mathtype == "add"){
cout << "The numbers added equal " << Addition(num1, num2) << endl;

}

int Addition(int x, int y){
int useranswer;
useranswer = x + y;
return useranswer;
}



I have tried adding the other Subtraction and Multiplication methods, but they don't work either. Where am I missing the }?

Thanks in advance!
