C++ code builds in CodeBlocks but not in Visual Studio 2015 - c++

Question

I was given sample code in a C++ course I am taking. I can get it to build in CodeBlocks but not in Visual Studio 2015. In Visual Studio the main line "rename test3;" raises an error looking for a semicolon and the variable declaration in that line, "rename", is not highlighted in the default green for a type as it should be. Same for the next line. Therefore test3 and test4 come up as undefined. If I remove "#include <iostream>" "rename" turns to green in lines 33 and 34 but then the std include become undefined. Implementing "using namespace std" doesn't help either. I am attempting to get rid of "using namespace std" as it is not good coding practice from what I understand around here. I am missing a VS setting I think.
//#include <iostream> // original first two line
//using namespace std; //
#include <iostream>
#include <cstring> // I added this include
using std::cin; // I added the following using lines
using std::cout;
using std::endl;
class feature { // this class has a specific feature
private:
char data[16];
public:
feature() { strcpy(data, "default"); }
feature(char * in) { strcpy(data, in); } // error checks needed
void set(char * in) { strcpy(data, in); }
void out() { cout << data << endl; }
};
class rename : private feature {
public:
void reset(char * in) { set(in); }
void print() { out(); }
rename() : feature() {}
rename(char * in) : feature(in) {}
};
int main() {
feature test1;
feature test2("test2 data");
rename test3;
rename test4("test4 data");
test1.out();
test2.out();
test3.print();
test4.print();
}
The results should be:
default
test2 data
default
test4 data
default
test4 data
If I change back to the original first two lines the code does not work. If I rename "rename" to "rename1" then the code works.
#include <iostream>
using namespace std;
class feature { // this class has a specific feature
private:
char data[16];
public:
feature() { strcpy(data, "default"); }
feature(char * in) { strcpy(data, in); } // error checks needed
void set(char * in) { strcpy(data, in); }
void out() { cout << data << endl; }
};
class rename1 : private feature {
public:
void reset(char * in) { set(in); }
void print() { out(); }
rename1() : feature() {}
rename1(char * in) : feature(in) {}
};
int main() {
feature test1;
feature test2("test2 data");
rename1 test3;
rename1 test4("test4 data");
test1.out();
test2.out();
test3.print();
test4.print();
}

rename is a function that gets included by the header <cstring> in Visual Studio, which causes a conflict with the name of your class. You therefore need to change the name of your derived class. Visual Studio will probably also require you to change strcpy to strcpy_s (it may either give a Warning or Error otherwise).
Ideally you should avoid using C compatibility headers in new code you write (unless you absolutely need them), e.g.: in your example you should stick to std::string instead of char*
