String class

replace()

String::replace, replace, String.replace

The String replace() function allows you to replace all instances of a given character with another character. You can also use replace to replace substrings of a string with a different substring. This modified the object, not a copy.

// SYNTAX

// PROTOTYPES
String& replace(char find, char replace);
String& replace(const String& find, const String& replace);

Parameters:

• string: the string which will be modified - a variable of type String
• substring1: searched for - another variable of type String (single or multi-character), char or const char (single character only)
• substring2: replaced with - another variable of type String (single or multi-character), char or const char (single character only)

Returns: A reference to the String object (*this).
