class header: error: expected unqualified-id before 'char' while compiling - c++

Question

Sorry for bad english.
I am new on c++ and trying to understand to send references to class object.
But I get above error. If I use const char then error comes up for 'const' part.
Here is my code:
main:
#include <iostream>
#include "DelMe-ClassHeader.h"
using namespace std;
int main() {
char var1 [2];
int var2;
for (int i = 0; i < 2; i++) {
var1[i] = 2;
}
int var2 = 0;
tc = TestClass(var1, var2);
cout << "before tc.changeValue" << endl;
cout << "var1 is " << var1 << endl;
cout << "var2 is " << var2 << endl;
tc.changeValue()
cout << "before tc.changeValue" << endl;
cout << "var1 is " << var1 << endl;
cout << "var2 is " << var2 << endl;
}
header:
#ifndef TestClass
#define TestClass
#include <iostream>
using namespace std;
class TestClass {
public:
TestClass(char (& first)[2]}, int& second);
void changeValue ();
private:
char (& privArray)[2];
int& privInt;
};
#endif
cpp:
#include "DelMe-ClassHeader.h"
#include <iostream>
using namespace std;
TestClass::TestClass(char (& first)[15], int& second) {
this->priveArray = first;
this->privInt = second;
}
void TestClass::changeValue () {
privInt = atoi(privArray);
}
and the error is:
E:\Programing\CodeBlocks\Cpp\DelMe\DelMe\DelMe-ClassHeader.h|10|error: expected unqualified-id before 'char'
I gratefull for any help

Answer 1

The header contains two errors:
#define TestClass defines TestClass as an empty string. Therefore all occurences of TestClass will be replaced with an empty string, hence the errors. For more information read about the C++ preprocessor.
There is an extra } in the parameter list of TestClass.
Replace with this:
#ifndef TestClass_h_inc_
#define TestClass_h_inc_
#include <iostream>
using namespace std;
class TestClass {
public:
TestClass(char(&first)[2], int& second);
void changeValue();
private:
char(&privArray)[2];
int& privInt;
};
#endif
