Thread: Calling functions

Hello,

I have an assignment I have been struggling with,specifically with regards to calling a function from within a member function. Instead of using the actual assignment, I have thrown together an example to in hopes that someone could point me in the right direction. my example is comprised of two header files and two source files.

Code:

// somenum.h

#ifndef SOMENUM_H
#define SOMENUM_H



int aNumber(int num, int num2);


#endif


//second.h

#ifndef SECOND_H
#define SECOND_H




struct Value {
    
    int zero;
    int one;
    
    Value(int num1, int num2);
    
    void addNum (int value1, int value2);
}


//number.cpp

#include "second.h"
#include "somenum.h"

using namespace std;


Value value ( int a, int b)
{
    zero = a;
    one = b;
};


void Value::addNum(int someVal1, int someVal2)
{
    //call aNumber here, pass params
}



//somenum.cpp

#include "somenum.h"

using namespace std;

int aNumber(int num, int num2)
{
    int num3 = num + num2;
    
    return num3;
}

Hopefully my example makes sense, I didn't include a main() as it doesnt come into play at this point. Basically I want to call aNumber inside addNum, but I have not been able to figure out how to accomplish this. I have tried the following:

Code:

void Value::addNum(int someVal1, int someVal2)
{
   aNumber(someVal1, someVal2);
}

void Value::addNum(int someVal1, int someVal2)
{
   value.aNumber(someVal1, someVal2);
}

void Value::addNum(int someVal1, int someVal2)
{
   Value value;
   value.aNumber(someVal1, someVal2);
}

If someone could help me out I would greatly appreciate it.
