Need help on calling a member function of an object of a class in c++?

[MousehDragon]

So I have 3 classes, matrix.h, matrix.cc, and shortestPath.cc

shortestPath includes the .h file, which includes the matrix.cc file.

In shortestPath I've tried to call a Get method I wrote in the matrix.cc file, but I can't figure out how to call the function on the object of that class. This is the line of code I have:

char exp = mat.Get(0, 0);

I'm more concerned now with how to call the function on the object. the object of the matrix class is called mat. The parameters specify which character to return.

The Header (test.h)

//Donot include the cc
class test{
public:
void sayHello();
};

the test.cc

#include <test.h>
#include <iostream>
using namespace std;
void test::sayHello()
{
   cout<<"Hello\n";
}

the target class(target.cc)

#include <test.h>
class target{
public:
void callTest()
{
  test t;
  t.sayHello();
}
}
