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

The memcmp function compares the first n characters of the object pointed to by s1 to the first n characters of the object pointed to by s2. If the n characters of s1 and s2 are the same then it returns 0, otherwise, it returns a non-zero value. Syntax of memcmp in C: int memcmp(const

The strcmp function compares the string pointed to by s1 to the string pointed to by s2. If two strings are the same then strcmp() returns 0, otherwise, it returns a non-zero value. Syntax strcmp in C: int strcmp(const char *s1, const char *s2); Parameters: s1— pointer to the string1. s2— pointer to the string2

The strcat function appends a copy of the string to the end of the destination string (including the terminating null character). The initial character of the source string overwrites the null character at the end of the destination string. Note: If copying takes place between objects that overlap, the behavior is undefined. Syntax strcat in

The memset function copies the value of c (converted to an unsigned char) into each of the first n characters of the object pointed to by s. Syntax memcpy in C: void *memset(void *s, int c, size_t n); Parameters: s— pointer to the destination object. c— Value to be filled. n — Number of bytes
