Switch statementA switch statement allows you to easily chain conditional statements based on checking for exact individual values. The benefit of switch statements is that C compilers typically use what’s called a “lookup table” when turning them into machine code; this often makes programs run...
In which loop control structures can 'continue' be used? Can 'break' or 'continue' be used outside a loop? How does 'break' affect nested loops? Can 'break' be used to exit a switch statement? Is it mandatory to include 'break' after every 'case' in a 'switch' statement? Can '...

A serial port is a physical communication interface that enables the transfer of data between devices, such as a computer and a modem or a printer. It transmits data serially, which means that the bits of data are sent one after the other over a single wire. In contrast, a parallel port...

Some of C's most important features include: Fixed number of keywords, including a set of control primitives, such as if, for, while, switch and do while Multiple logical and mathematical operators, including bit manipulators Multiple assignments may be applied in a single statement. Function ret...
It is a machine-independent, structured programming language. Programs written in C are portable i.e., programs written for one type of computer or operating system can run on another type of computer or operating system with minimal modifications....
