c++ template vs code
A C++ template is a tool used to define a family of classes or functions based on one common template. It allows for the creation of generic types and functions. To create a C++ template, use the template
keyword followed by the template parameters and then the generic code that uses those parameters.
To use a C++ template, specify the template type(s) within angle brackets when declaring an instance of the template class or calling a template function.
Here's an example of a template class:
template <class T>
class MyTemplate {
T value;
public:
void setValue(T val) {
value = val;
}
T getValue() {
return value;
}
};
And an example of using the template class:
MyTemplate<int> intTemplate;
intTemplate.setValue(10);
int value = intTemplate.getValue();
When using a C++ template, be mindful of potential code bloat as each instantiation of a template will create a separate copy of the code for that particular type.
