| − | In computer programming, a string is a series of characters. The characters can be [[alphabet]]ic, numeric or special characters, or a combination thereof. '''String concatenation''', in very simple terms, is the joining of two strings. A numeric string must be converted to a numeric type before it can be used in calculations. Concatenation is language dependent and may have different operators depending on the computer programming language used.
