String.remove()

Description

Modify in place a String removing chars from the provided index to the end of the String or from the provided index to index plus count.

Syntax

myString.remove(index)

myString.remove(index, count)

Parameter Values

• myString: a variable of type String.
• index: The position at which to start the remove process (zero indexed). Allowed data types: unsigned int.
• count: The number of characters to remove. Allowed data types: unsigned int.

Return Values

• Nothing

Example Code

void setup() { Serial.begin(9600); String myString = "Arduino"; Serial.println(myString); // string before myString.remove(2, 2); Serial.println(myString); // string after } void loop() { }

The result on Serial Monitor:

COM6 Send Arduino Arino Autoscroll Show timestamp Clear output 9600 baud   Newline  

※ NOTES AND WARNINGS:

If the string is modified, it is highly recommended using String.reserve() to prevent the memory fragmentation issue
