fatal error:conio.h:No such file or directory

This error occurs when the compiler is unable to find the header file "conio.h" which is required for console input/output operations in C/C++ programming language.

The conio.h header file is not a standard C/C++ library header file and is only available in certain compilers like Turbo C++ or Borland C++.

To resolve this error, you can either use a different compiler that supports conio.h or remove the references to conio.h in your code and use alternative methods for console input/output operations.

Alternatively, you can try to download and install the conio.h header file from the internet and place it in the correct directory where the compiler can find it. However, this is not recommended as it may cause compatibility issues with other libraries and may not work properly.
