i have issues with inheritance.
I have 7 files: main.cpp,Utils.h,Utils.cpp,Loader.h,Loader.cpp,Calculation.h and Calculation.cpp.
Utils.h is inheriting from Loader.h and Calculation.h and
Loader.h is inheriting from Calculation.h.
1: main.cpp
#include <iostream>
#include <stdio.h>
#include <stdlib.h>
#include "Utils.h"
using namespace std;
int main()
{
Utils Tool;
Tool.Test();
return 0;
}
2: Utils.h
#ifndef UTILS_H_INCLUDED
#define UTILS_H_INCLUDED
#include <stdio.h>
#include <stdlib.h>
#include "Calculation.h"
#include "Loader.h"
class Utils:public Loader,public Calculation
{
public:
Utils();
void Test();
~Utils();
};
#endif // UTILS_H_INCLUDED
3: Utils.cpp
#include "Utils.h"
Utils::Utils():Calculation(),Loader()
{
}
void Utils::Test()
{
printf("Hello World\n");
int a=10,b=10;
printf("Result is: %d\n",Add(a,b));
Func();
}
Utils::~Utils()
{
}
4: Loader.h
#ifndef LOADER_H_INCLUDED
#define LOADER_H_INCLUDED
#include <stdio.h>
#include <stdlib.h>
#include <iostream>
#include "Calculation.h"
class Loader:public Calculation
{
public:
Loader();
void Func();
~Loader();
};
5: Loader.cpp
#include "Loader.h"
Loader::Loader():Calculation()
{
}
void Loader::Func()
{
printf("Great Loader\n");
}
Loader::~Loader()
{
}
6: Calcuation.h
#ifndef CALCULATION_H_INCLUDED
#define CALCULATION_H_INCLUDED
#include <stdio.h>
#include <stdlib.h>
#include <iostream>
class Calculation
{
public:
Calculation();
int Add(int a,int b);
~Calculation();
};
#endif //CALCULATION_H_INCLUDED
7: Calculation.cpp
#include "Calculation.h"
Calculation::Calculation()
{
}
int Calculation::Add(int a,int b)
{
return a+b;
}
Calculation::~Calculation()
{
}
When i try to compile the code it fails. I receive a error message:
C:\Users\MY_NAME\Documents\CodeBlocksProj\Inheritance_Test\Utils.cpp: In member function 'void Utils::Test()':
C:\Users\MY_NAME\Documents\CodeBlocksProj\Inheritance_Test\Utils.cpp:18:31: error: reference to 'Add' is ambiguous
