Escape Sequences in "string" Literals

∟Escape Sequences in "string" Literals

This section describes Escape Sequences in 'string' literals

Escape sequences must be supported to allow us to enter the double-quote (") itself, in the string.

So escape sequences is supported with the leading character of "\" with 4 simple rules:

If \ is followed by \ ("\\"), the escape sequence represents the \ character.
If \ is followed by " ("\""), the escape sequence represents the " character.
If \ is followed by any other escape sequence name character to be defined in H language, the escape sequence represents the defined value. For example, "\n" represents the new-line character.
If \ is followed by non-defined escape sequence name character, the escape sequence represents that character itself. For example, "\9" represents the character 9.

Examples of "string" literals with escape sequences:

"Computer says: \"Invalid character: \\\"";
# The above "string" literals represents:
#    Computer says: "Invalid character: \";

"How many slashes in the string: \\\\\\\\\\?";
# The anwser is 5
