Inheritnace problem

this inheritance program is giving me problems about decleration on lines 17 and 20.

---------------------------------------------------------------------------------

#include <iostream.h>
#include <string.h>

class Pair {
public:
Pair (int num1, int num2) {
aNum1 = num1;
aNum2 = num2;
}
Pair () {
aNum1 = 0;
aNum2 = 0;
}
void output () {
cout << aNum1 << " " << aNum2 << endl;
}
setNum1 (int num) {
aNum1 = num;
}
setNum2 (int num) {
aNum2 = num;
}
private:
int aNum1;
int aNum2;
};

main () {

Pair numPair (12, 34);
numPair.output ();
numPair.setNum2 (21);
numPair.output ();

}

>setNum1 (int num) {
and
>setNum2 (int num) {
Both of these method definitions are missing a return type, put void in front of them both and it should compile fine (with a warning about main not returning a value of course).

-Prelude

Also, if you define functions in your class definition, you also need a semicolon after the bracket signaling the end of the function definition.

>you also need a semicolon after the bracket signaling the end of the function
It isn't required, but is sometimes considered good style. I personally don't see the need, but I rarely define functions inside my class definition anyway.
