C++Definition Method of Function Accepting Any Number of Parameters (Detailed)

A function that can accept any number of parameters can be implemented using overloading. The execution process of this function is similar to recursive calls, so there must be a recursive termination condition.

#include <iostream>
#include <bitset>
void print() {} // Recursive termination condition. This is necessary.
template<typename Type, typename... Types>
void print(const Type& arg, const Types&... args)
{
  std::cout << arg << std::endl;
  print(args...);
}
int main()
{
  print(1, 3.1415, "Hello, world!", 1.618, true, std::bitset<16>(377, 40);
  return 0;
}

The result after execution is as follows:

1 
3.1415 
Hello, world! 
1.618 
1 
0000000101111001 
40 

That's all the C++This is all about the method of defining a function that can accept any number of parameters (detailed explanation), I hope everyone will support and cheer for the tutorial!
