what is a template in c++

Comment

A template is a simple and yet very powerful tool in C++. The simple idea is to
pass data type as a parameter so that we don’t need to write the same code for
different data types.

For example, a software company may need sort() for
different data types. Rather than writing and maintaining the multiple codes,
we can write one sort() and pass data type as a parameter.
  
C++ adds two new keywords to support templates: ‘template’ and ‘typename’. The
second keyword can always be replaced by keyword ‘class’.

C++ template function

Comment

/*
C++ template functions are an alternamive way to write a function that
can take different data types. C++ Template functions are only one
function, so if you need to make a change, then it only has to be done
once. Here is an example of a 'get_doubled' templated function:
*/

#include <iostream>
using std::cout;

template <typename T> // Now, T is a type of variable, for this scope:
void say_something(T input) {
  cout << input << "\n";
}

int main(void) {
  say_something(45); // Uses a int
  say_something("Hello"); // Uses a string
  say_something(90.5); // Uses a float/double
  return 0;
}
