#Strings in C

All strings in C are:

• Stored as an array of characters
• End with a 'sentinal' character (Null character which is /0 in ASCII)
• Use single quotes for single characters, double quotes for longer strings

###String Literals

char *s = "string literal"

• Immutable (can't be changed after assignment.)
• Stored in 'Read Only' memory, so you can't pass it around.

###Character Arrays

/* To store three initials, we need an array of length 4 */
/* Because of the 'sentinal' character */
char initials[4]
initials[0] = 'A'
initials[1] = 'B'
initials[2] = 'C'

/* Shorthand: */
char initials[] = "ABC";

• Character arrays are mutable (can be changed after assignment), but have a static length.
