#include <string.h>, syntax at the beginning of our code, means we automatically included these (pre-defined) functions in our program:
char *strcpy(char *dest, const char *src);
char *strncpy(char *dest, const char *src, size_t maxlen);
char *strcat(char *dest, const char *src);
size_t strlen(const char *s);
char *strlwr(char *s);
char *strupr(char *s);
int strcmp(const char *s1, const char *s2);
int strcmpi(const char *s1, const char *s2);
int stricmp(const char *s1, const char *s2);
int strncmp(const char *s1, const char *s2, size_t maxlen);
int strncmpi(const char *s1, const char *s2, size_t maxlen);
int strnicmp(const char *s1, const char *s2, size_t maxlen);
char *strchr(const char *s, int c);
char *strstr(const char *string, const char *substring);

nice
this doesnt teach ANYTHING
