    Why do I get error: a function-definition is not allowed here before '{' token

    I am trying to write 4 functions for 4 operators but can not figure out what I am doing wrong. I get the error a function-definition is not allowed here before '' token. I have tried moving and changing everything for hours but no luck. Any help would be much appreciated. thanks.

    Code:
    #include <iostream>
#include <string>
using namespace std;
 void add( int , int );
 void subtract( int , int );
 void multiply( int , int );
 void divide( int , int );

  int main ()

  {
  int a;
  int b;
  int operato;

      cout << "Please enter your first number ";
      cin  >> a;
      cout << "Please enter your second number ";
      cin >> b;
      cout << "Please choose one of the following with the number only: " << endl;
      cout << '\t' << " 1) Add " <<  endl;
      cout << '\t' << " 2) Subtract " << endl;
      cout << '\t' << " 3) Multiply " << endl;
      cout << '\t' << " 4) Divide " << endl;
      cin >> operato;

      if (operato == 1)
      {
          cout << a << " + " << b << " = " << add << endl;
      }
      else if (operato == 2)
      {
          cout << a << " - " << b <<  " = " << subtract << endl;
      }
      else if (operato == 3)
      {
          cout << a << " * " << b <<  " = " <<  multiply << endl;
      }
      else //operator == 4
      {
          cout << a << " / " << b <<  " = " << divide << endl;
      }
  int add(int a, int b)
  {
      return a + b;
  }
  int subtract(int a, int b)
  {
      return a - b;
  }
  int multiply( int a, int b)
  {
      return a * b;
  }
  int divide( int a, int b)
  {
      return a / b;
  }

  }

    You are trying to pass a function to your output stream:
    Code:
    cout << add << endl;
    But what you need to do is invoke it (you want its output), and with the variables you introduced:
    Code:
    cout << add(a, b) << endl;
    Also, your function definitions shouldn't be inside the main function itself; you can move them below it. And their signatures don't match your declaration:
    Code:
    void add(int, int); // void return type
int add(int a, int b) // int return type (what you want)
{ }

    Sorry but I am now more confused with more errors. I added the "invocation" with the add(a, b). Then I tried to put the functions below main and then the compiler just generated a ton of errors.

    Code:
    #include <iostream>
#include <string>
using namespace std;
void add( int a, int b );
void subtract( int a, int b );
void multiply( int a, int b );
void divide( int a, int b);
int main ()
{
int a;
int b;
int operato;
    cout << "Please enter your first number ";
    cin  >> a;
    cout << "Please enter your second number ";
    cin >> b;
    cout << "Please choose one of the following with the number only: " << endl;
    cout << '\t' << " 1) Add " <<  endl;
    cout << '\t' << " 2) Subtract " << endl;
    cout << '\t' << " 3) Multiply " << endl;
    cout << '\t' << " 4) Divide " << endl;
    cin >> operato;

    if (operato == 1)
    {
        cout << a << " + " << b << " = " << add(a, b) << endl;
    }
    else if (operato == 2)
    {
        cout << a << " - " << b <<  " = " << subtract(a, b) << endl;
    }
    else if (operato == 3)
    {
        cout << a << " * " << b <<  " = " <<  multiply(a, b) << endl;
    }
    else //operator == 4
    {
        cout << a << " / " << b <<  " = " << divide(a, b) << endl;
    }
}
int add(int a, int b)
{
    return a + b;
}
int subtract(int a, int b)
{
    return a - b;
}
int multiply( int a, int b)
{
    return a * b;
}
int divide( int a, int b)
{
    return a / b;
}

    Notice that you forward declared the functions as having a return type of void:
    Code:
    void add( int a, int b );
void subtract( int a, int b );
void multiply( int a, int b );
void divide( int a, int b);
    But you correctly defined them as having a return type of int.

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    Probably to do with the functions signatures i mentioned. On line 4 you declare
    Code:
    void add(int, int)
    But on line 41 you define it as
    Code:
    int add(int a, int b)
    The int return type is what you want here, so change lines 4, 5, 6, 7 to return int as well, just like you definitions at the bottom.

    If that doesn't solve it, consider pasting your compiler errors. You can also use a service like pastebin or so, if you don't want to post a wall of text.

    I don't know if this helps. To me it is just a big mess. Thank you for your help.

    Have you made the fixes concerning the return type of the functions as mentioned by Guest in posts #2 and #5 and by me in post #4? Fixing those will likely remove the huge chunk of error messages that you're seeing. A huge chunk of error messages don't always mean a huge swath of errors as a single error can result in such a lengthy error message, especially when template code is involved.

    If you have made the fixes, then post your current code. If you have not, then make them and compile.

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    laserlight I guess I didn't know you told me to make a change somewhere. I know you said I forward declared the functions but I didn't know where to make changes. Here is what I have now that the compiler gave the above errors. Thanks for the help.

    Code:
    #include <iostream>
#include <string>
using namespace std;
void add( int a, int b );
{
    return a + b;
}
void subtract( int a, int b );
{
    return a - b;
}
void multiply( int a, int b );
{
    return a * b;
}
void divide( int a, int b);
{
    return a / b;
}

int main ()
{
int a;
int b;
int operato;
    cout << "Please enter your first number ";
    cin  >> a;
    cout << "Please enter your second number ";
    cin >> b;
    cout << "Please choose one of the following with the number only: " << endl;
    cout << '\t' << " 1) Add " <<  endl;
    cout << '\t' << " 2) Subtract " << endl;
    cout << '\t' << " 3) Multiply " << endl;
    cout << '\t' << " 4) Divide " << endl;
    cin >> operato;

    if (operato == 1)
    {
        cout << a << " + " << b << " = " << add(a, b) << endl;
    }
    else if (operato == 2)
    {
        cout << a << " - " << b <<  " = " << subtract(a, b) << endl;
    }
    else if (operato == 3)
    {
        cout << a << " * " << b <<  " = " <<  multiply(a, b) << endl;
    }
    else //operator == 4
    {
        cout << a << " / " << b <<  " = " << divide(a, b) << endl;
    }
}
int add(int a, int b)
{
    return a + b;
}
int subtract(int a, int b)
{
    return a - b;
}
int multiply( int a, int b)
{
    return a * b;
}
int divide( int a, int b)
{
    return a / b;
}

    FYI: By fixing the function prototypes no one meant you to turn them into function with syntax errors.

    Code:
    void add( int a, int b ); // This ";" is causing this function syntax and the errors.
{
    return a + b; // void means there is no return of value allowed.
}

    Finally! Thank you everyone. However, this is now similar to what I actually did EXCEPT I used result instead of return when I was declaring my functions. Can someone tell me the difference between return and result and when you use them? Thanks for the help on this!

    Code:
    #include <iostream>
#include <string>
using namespace std;
int add( int a, int b )
{
    return a + b;
}
int subtract( int a, int b )
{
    return a - b;
}
int multiply( int a, int b )
{
    return a * b;
}
int divide( int a, int b)
{
    return a / b;
}

int main ()
{
int a;
int b;
int operato;
    cout << "Please enter your first number ";
    cin  >> a;
    cout << "Please enter your second number ";
    cin >> b;
    cout << "Please choose one of the following with the number only: " << endl;
    cout << '\t' << " 1) Add " <<  endl;
    cout << '\t' << " 2) Subtract " << endl;
    cout << '\t' << " 3) Multiply " << endl;
    cout << '\t' << " 4) Divide " << endl;
    cin >> operato;

    if (operato == 1)
    {
        cout << a << " + " << b << " = " << add(a, b) << endl;
    }
    else if (operato == 2)
    {
        cout << a << " - " << b <<  " = " << subtract(a, b) << endl;
    }
    else if (operato == 3)
    {
        cout << a << " * " << b <<  " = " <<  multiply(a, b) << endl;
    }
    else //operator == 4
    {
        cout << a << " / " << b <<  " = " << divide(a, b) << endl;
    }
}

    What does this even mean?
    The original problem was basically that you mixed up your declarations and definitions:

    Declaration:
    void add( int a, int b );

    Definition:
    int add( int a, int b )

    The declarations and definitions must look EXACTLY the same (except the definitions must provide a body, while the declarations ends with a semicolon).

    I'm sorry I meant before I posted on the site. I tried a lot of coding before I posted. Thanks for the help!
