an unavailable function

Question

Why can't the sentence "gotoxy(int_x,int_y)"(conio.h) go on PC IDEs like Dev-Cpp?It's OK on C4droid.

Answer 1

Because gotoxy() and conio.h both are non standard stuff that you are using, while you can still get away with using those if you are using an ancient compiler to compile your code, but can't do this in any modern standard C/C++ compiler.

P.S. there is also a defination of gotoxy() in windows API header (windows.h) but that is platform dependent.
