Consider the following template function in your program
template<class T>
void printme(T a)
{
std::cout<<a<<std::endl;
}
Now assume that you have called this function 3 times in your
program as follows,
printme<int>(5);
printme<int>(48);
printme<double>(4.54);
Here template function printme is used for types int and double
in the program. So compiler will internally create an two functions printme as follows
void printme(int a)
{
std::cout<<a<<std::endl;
}
void printme(double a)
{
std::cout<<a<<std::endl;
}
