Enfunction Template C

Enfunction Template C - We have defined a template class T so template class T is a definition of T which is defined as a class of type template So the function is a template function We have written the same logic but instead of data type int or float we have replaced them with T Now let us write the main function int main

26 3 Function template specialization When instantiating a function template for a given type the compiler stencils out a copy of the templated function and replaces the template type parameters with the actual types used in the variable declaration This means a particular function will have the same implementation details for each

Enfunction Template C

With function templates, you can specify a set of functions that are based on the same code but act on different types or classes. The following function template swaps two items: C++. // function_templates1.cpp template< class T > void MySwap( T& a, T& b ) T c(a); a = b; b = c; int main() This code defines a family of functions that ...

Swapping two numbers using template function in C++. A significant benefit of object-oriented programming is the reusability of code which eliminates redundant coding. An important feature of C++ is called templates. Templates support generic programming, which allows to development of reusable software components such as functions, classes ...
