C++ template example

#include <iostream>
using namespace std;
  
// One function works for all data types.  This would work
// even for user defined types if operator '>' is overloaded
template <typename T> T myMax(T x, T y)
{
    return (x > y) ? x : y;
}
  
int main()
{
    cout << myMax<int>(3, 7) << endl; // Call myMax for int
    cout << myMax<double>(3.0, 7.0)
         << endl; // call myMax for double
    cout << myMax<char>('g', 'e')
         << endl; // call myMax for char
  
    return 0;

C++ template

/*
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;
}

template <class Type> 
void Swap( Type &x, Type &y)

    Type Temp = x;
    x = y; 
    y = Temp;

template in cpp

// templates are used if the logic of function is same but 
// it differs due to data type.

/*Here is an example to show how user defined function print 
can be made to print  data of different data types.*/ 

template <class T>
T print (T a)
{
   cout << a;
}

int main()
{
    print('a');
    print(1);
}

templates of templates c++

namespace std {
  template<typename t> struct hash<MyClass<t>>
  {
  	size_t operator() (const MyClass<t>& c) const;
  }
}

// You can also do things like

template<template<typename t> class type> func_name<type<t>>();
Comment

c++ template

template <class  T>//or <typename T> it´s the same
 //T can be int, float, double, etc. 
//simple use example: 
T sum(T a, T b)
{
  return a + b;
}
sum(5.0f, 10f);//sum using float
sum(2,3);//sum using int
