MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -In formal language theory and computer programming, string concatenation is the operation of joining character strings end-to-end. For example, the concatenation of “snow” and “ball” is “snowball". In certain formalisations of concatenation theory, also called string theory, string concatenation is a primitive notion.

Detailed explanation-2: -Concatenation is the process of appending one string to the end of another string. You concatenate strings by using the + operator. For string literals and string constants, concatenation occurs at compile time; no run-time concatenation occurs.

Detailed explanation-3: -: a group of things linked together or occurring together in a way that produces a particular result or effect. an unusual concatenation of circumstances.

Detailed explanation-4: -Concatenation operators join multiple strings into a single string. There are two concatenation operators, + and & . Both carry out the basic concatenation operation, as the following example shows.

Detailed explanation-5: -Concatenation means joining strings together end-to-end to create a new string. To concatenate strings, we use the + operator. Keep in mind that when we work with numbers, + will be an operator for addition, but when used with strings it is a joining operator.
