The initial character of s2 overwritesthe null character at the end of s1. The behaviour of strcat is undefined if copying takesplace between objects that overlap.strcat returns the value of s1.strcat conforms to ISO/IEC 9899:1990 (C90) and ISO/IEC 9899:1999 (C99).strchrSynopsisDescriptionPortability#include char *strchr(const char *s, int c);strchr locates the first occurrence of c (converted to a char) in the string pointed to bys. The terminating null character is considered to be part of the string.strchr returns a pointer to the located character, or a null pointer if c does not occur inthe string.strchr conforms to ISO/IEC 9899:1990 (C90) and ISO/IEC 9899:1999 (C99).See also memchr (page 311)strcmpSynopsis#include int strcmp(const char *s1, const char *s2);Chapter 28 - String handling313
