/*
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 << "
";
}
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;
}
