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

The atexit function registers the function pointed to by func and this registered function called without arguments when the program terminates normally. In case of more than one atexit function, the registered functions are called in the reverse order of their registration (i.e. the last function specified is the first to be executed at exit).

The abort function terminates the execution of a current process abnormally. When the abort function is called it raises the SIGABRT signal to cause abnormal termination of the current process. The abort function defined in the ‘stdlib.h’ header file, so you have to include the header file before using it. Syntax abort in C: //Syntax

The div, ldiv, and lldiv, functions compute quotient (numer / denom ) and remainder (numer % denom ) in a single operation. These functions div, ldiv, and lldiv, are defined in stdlib.h header file and returns a structure that comprises the quotient and the remainder. So let see these function one by one with some

The abs, labs, llabs functions compute the absolute value of an integer. These functions abs, labs, llabs are defined in stdlib.h header file. The behavior of these functions is undefined if the result cannot be represented by the return type. So let see these function one by one with some example code. abs(): The abs

The strpbrk function scan the string s1 and finds the first character in the string s1 that matches any character specified in string s2. The search does not include the terminating null-characters of either string but ends there. Syntax strpbrk in C: //General Syntax of strpbrk char *strpbrk(const char *s1, const char *s2); Parameters: s1— The

The strspn function scan the string pointed to by s1 and computes the length of the maximum initial segment of the string which consists entirely of characters from the string pointed to by s2. it means strspn returns the length of the initial segment of s1 which consists only of characters that are part of
