String Literals as Initializers

A string literal may be used as an initializer in the declaration of either a built-in array of chars or a variable of type const char *. The declarations

each initialize a variable to the string "blue". The first declaration creates a five-element built-in array color containing the characters 'b', 'l', 'u', 'e' and ''. The second declaration creates pointer variable colorPtr that points to the letter b in the string "blue" (which ends in '') somewhere in memory. String literals have static storage duration (they exist for the duration of the program) and may or may not be shared if the same string literal is referenced from multiple locations in a program.
