system() is used to invoke an operating system command from a C/C++ program.

Answer 2

Answer:

system() is used to invoke an operating system command from a C/C++ program.

Explanation:

• The act of creating systems software using system programming languages is referred to as system programming. Hardware is the item that is last in the computer hierarchy. Next comes the operating system, followed by system programmes and then application programmes.
• System programmes make it simple to develop and execute programmes. Other System Programs are complex, while others are just user interfaces. It typically sits between system calls and the user interface.
• In this case, the user can only see System Calls but not System Programs.
• These categories can be used to categorise system programmes:

Management of files

• A file is a grouping of particular data kept in a computer system's memory. The process of creating, modifying, and deleting files is included in the definition of file management, which is the manipulation of files within a computer system.
• Making new files and putting them in specific places on the computer system is helpful.
• It facilitates quickly and easily finding these files within the computer system.
• It makes file sharing among various users a very simple and user-friendly process.
• The organisation of files into distinct directories is beneficial.

Status Information - Some users request information such as the date, time, amount of available memory, or disc space. Others offer more complex and detailed performance, logging, and debugging information. All of this data is formatted before being printed or displayed on output devices. Program output is displayed using a GUI window, a terminal, or other output devices or files.

File Modification - We use this to change the contents of files. We used various types of editors for files kept on discs or other storage devices. We use specific commands to perform file transformations or search their contents.

Support for programming languages - We use compilers, assemblers, debuggers, and interpreters for popular programming languages that are already available to users. It offers users all forms of assistance. Any programming language can be used by us. All relevant languages are already available.

Program Loading and Execution - After assembly and compilation, the programme must be loaded into memory before it can be run. An operating system component called a loader is in charge of loading libraries and programmes. It's one of the crucial steps in beginning a programme. The system offers loaders, relocatable loaders, linkage editors, and overlay loaders.

Communications - Programs provide virtual connections between processes, users, and computer systems. Users can browse websites, log in remotely, send messages to other users via their screens, send emails, and transfer files from one user to another.
