String class

equalsIgnoreCase()

Compares two strings for equality. The comparison is not case-sensitive, meaning the String("hello") is equal to the String("HELLO").

// SYNTAX
string.equalsIgnoreCase(string2)

// PROTOTYPE
unsigned char equalsIgnoreCase(const String &s) const;

Parameters:

• string, string2: variables of type String

Returns:

• true: if string equals string2 (ignoring case)
• false: otherwise

This function only works properly with 7-bit ASCII characters. It does not correctly compare other character sets such as ISO-8859-1 or Unicode UTF-8.
