In C++, which operator is used for concatenation of two character arrays?

  1. +

  2. .

  3. ::

  4. None, C++ does not allow direct concatenation

The correct answer is: None, C++ does not allow direct concatenation

In C++, the operator + is used for concatenation of two strings, not character arrays. Option B, the dot operator, is used for accessing members of an object and has no role in concatenation. Option C, the scope resolution operator, is not used for character array concatenation but for accessing members of a namespace or class. Option D is the correct answer as C++ does not provide a built-in concatenation operator for character arrays, but it can be achieved through other methods such as using the strcat function or overloading the + operator for character arrays.
