How to Include

The C string functions in the standard library are available by using

#include <string.h>

String functions

strlen

Returns the length of a string.

strcmp

Compares two strings. (Remember, a string is an array of characters, so you can't just use the == operator to test for equality, just as in Java). Returns 0 (i.e. false!) if the two strings are equal.

strncmp

Compares the first n characters of two strings.

strcat

Append one string on to the end of another.

strcpy

Copies a string.

strncpy

Copies the first n characters of a string.

strchr

Finds the next occurrence of a certain character in a string.

strtok

Breaks a string up into tokens. The syntax for this function is kind of strange, so be sure to read the man page.
