What is the principle of a template in C ++?

Question

And what template library should a new user be?

Not sure if OS matters, I'm talking about Windows if that matters.

Answer 1

For beginners, it's best to start with a good book . The standard library (often also called STL) is the template library you should start with.

Answer 2

Templates are general programming. The concept is this: you define the body / class of a function that will work with any data (having some properties, like a specific operator). Suppose you write a function that will return a summation of its given parameters:

int sum(int a, int b)
{
    return a + b;
}

, . :

std::string s1 = "abc", s2 = "def";
std::string s = sum(s1, s2);

sum() sum(). . sum() :

template<typename T>
T sum(const T& a, const T& b)
{
    return a + b;
}

sum() , operator+.

STL ( ), ++.
