Using gotoxy() in Dev-C++

How To Uncomment In C Using Dev C By

gotoxy() is a standard C function defined in <conio.h>, but it will not work in ANSI C compilers such as Dev-C++. Why? Because gotoxy() is a Turbo-C++ specific function, which means it is not part of the standard. However, if you insist on using console functions, you can define your own function by using member functions available in <windows.h>

To use gotoxy() in Dev-C++, #include <windows.h> and insert this snippet before the main() function:


//Defines gotoxy() for ANSI C compilers.
void gotoxy(short x, short y) {
COORD pos = {x, y};
SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), pos);
}

C++ comments start with /* and end with */. For example −
