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

The strcspn 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 not from the string pointed to by s2. It means strcspn scan s1 until the first occurrence of any characters that are part of s2. Syntax strcspn in

In my one project, I have used the strtok function to parse the server response in TCP/IP client-server communication. I have also used the strtok function many times to parse the string. If you are going to use the strtok in C, then you should know about it. Because if you don’t have much knowledge

The strncat function appends n characters from the array pointed to by s2 (source) to the end of the string pointed to by s1 (destination). The initial character of s2 overwrites the null character at the end of s1. It means character s2[0] replaces the null terminator at the end of s1. Syntax strncat in

The strrchr function finds the last occurrence of c (converted to a char) in the string pointed to by s. The terminating null character is also considered to be part of the string and it can be found if searching for ‘\0’. The strrchr function defines in string.h header file and takes two arguments. Syntax

The memchr function finds the first occurrence of c (converted to an unsigned char) in the initial n characters (each interpreted as unsigned char) of the object pointed to by s. The behavior of memchr is undefined if we try to access beyond the end of the array searched. The behavior is undefined if s

The strxfrm function transforms (into a new collated form) the string pointed to by s2 and places the resulting string into the array pointed to by s1. The transformation is made using the locale’s LC_COLLATE category setting and No more than n characters, including the null character, are transformed and placed into the resulting array
