Which of the following statements about arrays in C++ is true?Arrays can store elements of different typesThe size of an array must be a constant expressionArray elements are accessed using parenthesesArrays can be resized after declaration
Solution
The statement "The size of an array must be a constant expression" about arrays in C++ is true.
In C++, arrays are static, which means they must be declared with a fixed size at compile time. This size must be a constant expression. The other statements are false. Arrays in C++ cannot store elements of different types, array elements are accessed using square brackets, not parentheses, and arrays cannot be resized after declaration.
