We have already written an article on bit operation and already covered many tricky questions related to bit manipulation. In this blog post, we will only discuss how to write macros for bit manipulation. So let’s see some macros for bit manipulation. If you are new and don’t know how to manipulate bits in C/C++ […]

If you are an embedded software developer, then believe me this article will help you. Before the C99, the C standard only introduced built-in types with no defined size. This ambiguity is intentional in the original C standard to give the compiler vendors more flexibility. But sometimes it creates a problem and reduces portability. According

The assert macro puts diagnostic tests into programs. It is a very good habit to implement a self-test in the program. It solves many critical issues. When the assert is executed, if the expression is false (0), the assert macro writes information about the particular call that failed on the standard error stream in an

The quick_exit function terminates the process normally without completely cleaning the resources. It defined in the ‘stdlib.h’ header file, so you have to include the header file before using it. The quick_exit function does not invoke the functions registered with atexit. But call the functions registered by the atexit function, in the reverse order of

The strlen function computes the length of the given string. It takes a string as an argument and returns its length. It doesn’t count the null character ( ‘\0’ ). The strlen() function defined in the <string.h> header file, so you have to include it before using it. Syntax strlen in C: //Syntax of strlen

The _Exit function terminates the process normally without completely cleaning the resources. It defined in the ‘stdlib.h’ header file, so you have to include the header file before using it. The _Exit function does not invoke the functions registered with at_quick_exit and atexit. Syntax _Exit in C: //Syntax of _Exit void _Exit(int status); (since C99

The exit function terminates the process normally also it performs the regular cleanup for terminating programs. It defined in the ‘stdlib.h’ header file, so you have to include the header file before using it. When the exit function invokes it performs several cleanup operations, these are the following. Call the functions registered by the atexit

C is a general-purpose, imperative computer programming language. It was originally developed by Dennis Ritchie between 1969 and 1973 at Bell Labs. The C language is used to re-implement the Unix operating system. It also has been standardized by the American National Standards Institute (ANSI) since 1989 and subsequently by the International Organization for Standardization
