A C++ syntax that I don't know.

[pdsilva]

Hi guys

I am new here.

Recently I began to work with c++, and I found a line in the code,that I don't know what it means.
Please give me an explanation about it.

Here it is:
std::material<s td::string, Classe1 *> mClasse1;

To me material is a methode of std.
mClasse1 is an object being declared,but what this means "<std::stri ng, Classe1 *>"I have never saw this kind of statement. What means operator "<" and ">".

Thank you in advance

[weaknessforcats]

std::material<std::string, Classe1 *> mClasse1;

This says that mClass1 is an object created from a template in the std namespace that was given std::string and a Class1* as parameters.

Like this:

template <class T>
class MyClass
{
public:
   T data;
};

Then in your program:

MyClass<int> myObject;

I'm not advocating public data but only explaining the syntax.
