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 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
