Question

in C++, when you define a function which takes one argument, you have to define the data type of that variable:

void makeProccess(int request)

However, I want to implement a function which takes different data types rather taking statically defined integer type.

void makeProccess(anyType request)

How can I design a proccess like this, any idea?

Thanks.

Use templates:

template <typename T>
void makeProcess(T request) {
  // request is of type "T", which can vary
  cout << "request: " << request;
}

An additional benefit, is you can specialize it:

template <>
void makeProcess(string request) {
  cout << "This is special handling for a string request: " << request;
}
