(b) Keyboard
(c) Mouse
(d) All of these
Answers
Answer:
The keyboard and monitor (b) and (a) are useful in C language I/O operations.
Explanation:
C language is a programming language used for various purposes, including system software development. Input/Output (I/O) operations are an essential part of any programming language, including C. In C, the standard I/O functions, such as printf and scanf, are used for input and output operations.
The input is taken from the keyboard, and the output is displayed on the monitor. The mouse does not play a role in C I/O operations. The keyboard and monitor are the most important components for C I/O operations, but the mouse is not required. In conclusion, only the keyboard and monitor (b) and (a) are useful in C language I/O operations.
