C++ Scope of template

[Digital]

So I am learning about C++ templates and I am using them to figure out the sources. Right now I only know how to use them for functions.

This is my template and the example code.

#include <iostream>

template<typename T>
void p(std::string s, T t){
    std::cout << s << " " << t << std::endl;
};

int main() {
    p("this is a float", 1.5);
    p("this is an integer", 24);
    p("this is a character", 'G');
    p("this is a string", "a string");
  
}

and this is how it works

this is a float 1.5
this is an integer 24
this is a character G
this is a string a string

When applied to the sources what would be the scope of a template if it were not defined inside of a class?

 

[Infernum]

if it were not defined inside of a class

you already used a template for a function that wasn't defined inside of a class in your example

Can I use it in other files?

 

[Infernum]

yes

 

[Digital]

yes

Can you give me an example?

 

[Digital]

bump

 

[Infernum]

copypaste the code into another file

you will be able to use that function in every file that includes that header/src where you defined it
