The Purpose of Templates

By this points you already have to know that templates can take a type as a parameter and we even can use it inside of it. Let's refresh our memory:

main


              12345678910111213
            
#include <iostream>

// Specifying the template parameter
//               VVV             
template<typename T> 
void MyFirstTemplate()
{
    // Using the template parameter
    //                 VVV
    std::cout << typeid(T).name() << std::endl;
}

int main() { MyFirstTemplate<void>(); }

And here hides the power of templates. If we can use the template parameter inside a template that means we can create a template function that can be used with any data type!
