The source-code interface is the same, but the binary code in the library has the standard-mode ABI. The other version is compiled from the same source code, but with the compiler in standard mode. One version is compiled with the compiler in compatibility mode, and is the same as the library used with C++ 4.2. Note - Two versions of the classic iostream runtime library are supplied with the compiler. Any existing iostream code that works with the 4.2 compiler should work exactly the same way when compiling in compatibility mode ( -compat). In compatibility mode, you get classic iostreams, the same version supplied with the C++ 4.2 compiler. It is better defined, feature-rich, and supports writing internationalized code. Standard C++ defines a new and expanded iostreams ( standard iostreams). The implementation is compatible with the version released with Cfront (1990), with some bug fixes.

The C++ 4.2 compiler implemented classic iostreams, which never had a formal definition.

Just copy file and paste file conio.h on /usr/include/ but don't forget before you want copy paste on /usr/include/ you must open folder as ADMINISTRATOR first !! Step 1 :

getch - Get char entry from the console.

cprintf - Formats values and writes them directly to the console.

cputs - Writes a string directly to the console.

putch - Writes a character directly to the console.

cscanf - Reads formatted values directly from the console.

gcgets - Reads a string directly from the console.kbhit - Determines if a keyboard key was pressed.Some of it's functions which are often used :
