c++ clas template instantiation code example
Example: c++ class template
#include <vector>
// This is your own template
// T it's just a type
template <class T1, class T2, typename T3, typename T4 = int>
class MyClass
{
public:
MyClass() { }
private:
T1 data; // For example this data variable is T type
T2 anotherData; // Actually you can name it as you wish but
T3 variable; // for convenience you should name it T
}
int main(int argc, char **argv)
{
std::vector<int> array(10);
// ^^^
// This is a template in std library
MyClass<int> object();
// This is how it works with your class, just a template for type
// < > angle brackets means "choose" any type you want
// But it isn't necessary should work, because of some reasons
// For example you need a type that do not supporting with class
return (0);
