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

The strncmp function compares not more than n characters (characters that follow a null character are not compared) from the array pointed to by s1 to the array pointed to by s2. Syntax of strncmp(): int strncmp(const char *s1, const char *s2, size_t n); Parameters: s1 − This is the first string to be compared.

The strstr function returns a pointer to the first occurrence of string s2 in string s1. The function returns the null pointer if the string is not found. The process of matching does not include the terminating null-characters(‘\0’). Syntax of strstr in C: char *strstr(const char *s1, const char *s2); Parameters: s1 − This
