Strcat char *strcat(char *dest, const char *src); strcat appends a copy of src to the end of dest The length of the resulting string is strlen(dest) + strlen(src) strcat returns a pointer to the concatenated Strings #include #include int...
Strchr char *strchr(const char *s, int c); Scans a string for the first occurence of a given character The null-terminator is considered to be part of the string If c does not occur in s, returns NULL #include #include int main() { char string[20]; char *ptr, c = 'r'; strcpy(string, "...
Strcmp int strcmp(const char *s1, const char*s2); strcmp performs an unsigned comparison of s1 to s2 Returned value: - 0 if s1 s2 #include #include int main() { char *buf1 = "alice", *buf2 = "andrew"; int p; p = strcmp(buf2, buf1); if (p 0)
Strcpy char *strcpy(char *dest, const char *src); Copies string src to dest - (order of arguments: like in an assignment ”dest=src”) #include #include int main() { char string[10]; /* long enough to hold a copy of str1 */ char *str1 = "first"; strcpy(string, str1);
Strpbrk char *strpbrk(const char *s1, const char *s2); strpbrk scans a string, s1, for the first occurrence of any character appearing in s2 On success, strpbrk returns a pointer to the first occurrence of any of the characters in s2 If no...
Strtok char *strtok(char *s1, const char *s2); strtok considers the string s1 to consist of a sequence of zero or more text tokens, separated by spans of one or more characters from the separator string s2 The first call to strtok - returns a po...
Summary of functions operating on raw memory memccpy copies a block of n bytes from src to dest memcpy copies a block of n bytes from src to dest memmove copies a block of n bytes from src to dest memchr searches the first n bytes of array ...
Inserting a new element: int insert(bn *p, bn **root) { if (*root && (*root)-data == p-data) return 1; /* already present */ if (!*root) { /* empty tree */ *root = p; return 0; } else if (p-data (*root)-data) insert(p,&((*root)-right)); else insert(p,&((*root)-left)); return 0; } i...
Memcpy void *memcpy (void *dest, const void *src, size_t n); Copies a block of n bytes from src to dest If src and dest overlap, the behavior is Undefined #include #include int main() { char src[] = ""; char dest[] = "abcdefghijlkmnopqrstuvwxyz0123456709"; char *ptr;
