C++ main function

Question

Does C++ support more data types on main function? (Like strings, doubles and int32_t)

Answer 1

what you put inside main is what is important. no need to change main's return type. It is just the entry point.

Answer 2

If you want to work with data types like strings, doubles, and int32_t within your program, you can use these data types inside the function body. However, when dealing with command-line arguments, they are initially passed as strings, and you may need to convert them to the desired types based on your program's logic

Answer 3

Bob_Li no it does affects when u need bigger than 32bit integers and u feel tedious to type long long everywhere or even a shorter macro for it better u change int to long long as macro and also return type of main from int to int32_t becomes a necessity
