Class String Name equalsIgnoreCase() Examples void setup() { Serial.begin(9600); String str1 = String("CCCP"); String str2 = String("ccCP"); // Tests to see if str1 is equal to str2 if(str1.equalsIgnoreCase(str2) == true) { // They are equal ignoring case differences so this line will print Serial.println("Equal"); } else { Serial.println("Not equal"); } } void loop() { // Nothing for loop() }String str1 = String("CCCP"); String str3 = String("cccp"); // Tests to see if str1 is equal to str3 void setup() { Serial.begin(9600); if(str1.equalsIgnoreCase(str3) == true) { // They are equal ignoring case differences so this line will print Serial.println("Equal"); } else { Serial.println("Not equal"); } } void loop() { // Nothing for loop() } Description Compares two strings to see if they are equal ignoriong case differences. This method is necessary because it's not possible to compare strings using the equality operator (==). Returns true if the strings are the same and false if they are not. Syntax equalsIgnoreCase(str) Parameters str String: any valid String Returns boolean Usage Application Updated on September 16, 2010 11:34:12pm PDT Wiring is an open project initiated by Hernando Barragán.
