What is the real use of getsch.....

Answer 1

getch() is actually used to read a single byte character from keyboard input without needing to press ENTER key. In past programs, getch() has been used to hold program execution (pause screen until a key is hit), but the function is now obsolete. Use getchar() instead.

I think VS still supports getch(), but you have to do _getch() instead. E.g.

int ASCII_num;

ASCII_num = _getch();

std::cout << ASCII_num;
