Strings: Strings are implemented as array of characters. The end of the string is always marked with a null character. Loops are used to manage the string, one character at a time. A test for the null character detects the end of the string. A string constant is specified by a set of double quotes. This string constant has an address; the address of the string. The strings address can be assigned to a pointer.

Examples: char course_name[] = Operating System;

char *depart_name = ICS;

char *colg_name = {C, C, S, E, \0};

A set of functions in the standard library is designed to perform common operations on strings.

These functions are defined in the header file strings.h.

\begin{tabular}{|l|l|} \hline Function name & Description \\ \hline strlen & finds the length of a string \\ \hline strcpy & copies a source string to another string \\ \hline stremp & compares two strings \\ \hline strcat & concatenates two strings. \\ \hline strtok & string tokenization \\ \hline \end{tabular}
