what is the use of command prompt in windows
cmd.exe Command Prompt, also known as cmd.exe or cmd (after its executable file name), is the command-line interpreter on Windows NT, Windows CE, OS/2 and eComStation operating systems. It is the counterpart of COMMAND.COM in DOS and Windows 9x systems (where it is also called "MS-DOS Prompt"), and analogous to the Unix shells used on Unix-like systems. The initial version of Command Prompt for Windows NT was developed by Therese Stowell.[1]
QBasic QBasic, a short form of Quick Beginners All purpose Symbolic Instruction Code, is an integrated development environment and interpreter for a variety of BASIC programming languages which are based on QuickBASIC. Code entered into the IDE is compiled to an intermediate representation, and this IR is immediately interpreted on demand within the IDE.[1] It can run under nearly all versions of DOS and 32-bit versions of Windows, or through emulation via DOSBox/DOSEMU on Linux, FreeBSD, and 64-bit versions of Windows.[2] (QBasic is a DOS program and requires DOS or a DOS emulator. Windows XP comes with an emulator called DOS Virtual Machine, subsequent versions of Windows require an emulator such as DosBox.) For its time, QBasic provided a state-of-the-art IDE, including a debugger with features such as on-the-fly expression evaluation and code modification. It supports various inbuilt functions.
