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();
}
