The # operator in Macros replaces the argument name with a string representing that argument name like:
#define MACRO(something) #something
#include <iostream>
int main()
{
std::cout << MACRO(wow); // it will print the string "wow"
return 0;
}
But can we reverse this, like send a string as a parameter and replace the string with the string content, idk how to explain so i will show you another example:
#define MACRO(something) (operator)something //converts the something argument which is a string to plain text
#include <iostream>
int main()
{
int MACRO("anything") = 0;
std::cout << MACRO("anything"); //it will print out 0
return 0;
}
