Function Template is a mechanism by which you can write
generic programs.Means you only need to create one framework
and based on your requirement you can write many
implementations.
one Framework is called Function Template.
Each implementation(function call) is called Template
Functions.
For your reference see the example below..
EX:
template <class T>
void swap(T &a,T &b) <----//This is Function Template.
{ T temp;
temp = a;
a = b;
b = temp;
}
int main()
{
int i1 = 5,i2 = 6;
float f1 = 2.2,f2 = 5.5;
char c1 = 'A',c2 = 'B';
cout<<"Before swapping i1 ="<<i1<<" i2 ="<<i2;
swap(i1,i2); <-----//This is 1 Template Function
cout<<"After swapping i1 ="<<i1<<" i2 ="<<i2;
cout<<"Before swapping f1 ="<<f1<<" f2 ="<<f2;
swap(f1,f2); <-----//This is 2 Template Function
cout<<"After swapping f1 ="<<f1<<" f2 ="<<f2;
cout<<"Before swapping c1 ="<<c1<<" c2 ="<<c2;
swap(c1,c2); <-----//This is 3 Template Function
cout<<"After swapping c1 ="<<c1<<" c2 ="<<c2;
return 0;
}
