Generic Functions : Template

Template

Used for generic programming.

Generic : - Generalized not bound with particular data type when we use method overloading , it will increase the size of the class . to avoid this , we use template.

Template types:

Function Template : -

 We can define function with generic template

Class template : -

We can define generic class .

Advantage :-

Reduce the size of code .

Better performance.

#include<iostream.h>

#include<conio.h>

template <class T>

T  highest(T n ,T m)

{

          if(n>m)

                   return n;

          else

                   returm m;

}

void main()

{

          clrscr();

          int  a=567;

          int  b=345;

          cout<<hight(a,b);

          cout<<highest(45.56f,34.64f)

          getch();

}

         Class Template: -

         #include<iostram.h>

         #include<conio.h>

         class a

          {

              private:

                       T  x;

              public:

                   a(T  r)

                   {

                             x=r;

}

void display()

{

          cout<<”value of x::”<<x;

}

         };

        void main()

        {

              clrscr();

               a <int> p(78);

               p.display();

               a <char> k(a);

               k.display();

               getch();

         }
