Question

Which of the following is a valid C++ array definition?

A) int scores[0];
B) float $payments[10];
C) int readings[4.5];
D) int scores [10];
E) None of these

Answer 1

The valid C++ array definition is int scores [10];

Step-by-step explanation:

The valid C++ array definition among the options provided is option D) int scores [10];

In C++, arrays are declared by specifying the data type followed by the name of the array and the number of elements it can store enclosed in square brackets. The size of the array must be a non-negative integer.

Option A) int scores[0]; is invalid because the size of the array cannot be zero. Option B) float $payments[10]; is invalid because variable names cannot start with a dollar sign in C++. Option C) int readings[4.5]; is invalid because the size of the array must be an integer.
