Chapter 7: Problem 6

Look at the following array definition. int numbers[5] = { 1, 2, 3 }; What value is stored in numbers[2]? What value is stored in numbers[4]?

Short Answer

Expert verified
Answer: The value stored at index 2 is 3, and the value stored at index 4 is 0.

Step by step solution

01

Understanding Array Initialization

In C, when an array is declared with a specific size and initialized with less elements than its size, the remaining elements will be automatically initialized with the value 0. In this case, the array 'numbers' is of size 5, but only three elements are provided (1, 2, and 3). Therefore, the remaining elements (numbers[3] and numbers[4]) will be initialized with the value 0.
02

Find the Value at Index 2

To find the value stored in numbers[2], we can simply look at the array initialization. The array is defined as int numbers[5] = { 1, 2, 3 }; Since array indices start from 0, the element at index 2 is 3. So, the value stored in numbers[2] is 3.
03

Find the Value at Index 4

To find the value stored in numbers[4], recall that the remaining elements of the array (after the initial 1, 2, and 3) will be initialized with the value 0, as explained in Step 1. So, the value stored in numbers[4] is 0.

When an array is passed to a function, the function has access to the original array.

The individual elements of an array are accessed and indexed by unique numbers.

C++ has no array _________ checking, which means you can inadvertently store data past the end of an array.

Look at the following array definition. double sales[8][10]; How many rows does the array have? How many columns does the array have? How many elements does the array have? Write a statement that stores a number in the last column of the last row in the array.
