Square Function using template specialization
Write a C++ Program of Square Function using template specialization. Here’s a Simple C++ Program of Square Function using template specialization in C++ Programming Language.
What are Templates in C++ ?
Templates are the foundation of generic programming, which involves writing code in a way that is independent of any particular type.
A template is a blueprint or formula for creating a generic class or a function. The library containers like iterators and algorithms are examples of generic programming and have been developed using template concept.
There is a single definition of each container, such as vector, but we can define many different kinds of vectors for example, vector <int> or vector <string>..
Function Template :
The general form of a template function definition is shown here:
template <class type> ret-type func-name(parameter list)
{
// body of function
}
Class Template :
Just as we can define function templates, we can also define class templates. The general form of a generic class declaration is shown here:
template <class type> class class-name
{
.
.
.
}
Below is the source code for C++ Program of Square Function using template specialization which is successfully compiled and run on Windows System to produce desired output as shown below :
SOURCE CODE : :
/* C++ Program of Square Function using template specialization */ #include <iostream> using namespace std; template <class T> inline T square(T x) { T result; result = x * x; return result; }; // template specialization template <> string square<string>(string ss) { return (ss+ss); }; int main() { int i = 2, ii; string ww("Aaa"); ii = square<int>(i); cout << i << ": " << ii << endl; cout << square<string>(ww) << endl; return 0; }
OUTPUT : :
/* C++ Program of Square Function using template specialization */ 2: 4 AaaAaa Process returned 0
Above is the source code and output for C++ Program of Square Function using template specialization which is successfully compiled and run on Windows System to produce desired output.
