Concatenation, also known as string concatenation, is a string operator that joins multiple text, string or other data together in a series without any gaps in a program to make a new text string. The general syntax to achieve concatenation is given below:
(data type)(concatenation operator)(data type)=(concatenated expression)
For example, In the Java programming language, the operator "+" denotes concatenation, as it does in other programming languages.
Consider two strings: snow+ball = snowball
The concatenation syntax in different programming languages is given below.
snow & ball: VB,VB.NET and Ada
strcat(snow, ball) : C, C++
snow.ball: Perl, PHP
snow || ball: REXX, SQL, FORTRAN
snow ++ ball: Erlang, Haskell
snow ^ ball: Ocaml, Standard ML, F#
