Question 51 pts

When passing an array to a called function, for example printArray(arrayName); the function receives ____ array.

Explanation / Answer

Question 1: The number 87 is passed to the printIt function.

In an array, the indexing starts from 0, i.e. the first element has index 0, second element has index 1 and so on. So index 2 is actually the third element, i.e. 87.

Question 2: int temp[4][2];

The format for declaring a 2D array is <data type> <array name> [rows][columns].

Question 3: 2

The array indexes start from 0, so if an array has 3 elements, the 3rd element will have index 2.

Question 4: 24

The array is stored in a row-major form i.e. row-wise. Hence val[1][2] is the third element of the second row. Hence it has an offset of (4 elements of first row + 2 elements of second row) i.e. 6*4 = 24.

Question 5: the first element of the

When an array is passed directly to a function, the function receives a pointer to the start of the array i.e. the first element of the array.
