Your colleague developed a function, which is supposed to reverse an array of integers, e. g., {1, 5, -10, 7, 23} => {23, 7, -10, 5, 1}. Test cases show that the function does not work correctly. Please look at the following code and identify all the troubles. Please specify which part(s) of the code will not work and explain why not. void ReverseArray(int arr[], size_t elements_no) {
size_t i = 0; int x = 0; for (i = 0; i <= elements_no; i++)
{ x = arr[i]; arr[i] = arr[elements_no - i]; arr[elements_no - i] = x; }

}

The parts of the code which makes the program not to work properly is:

1. for (i = 0; i <= elements_no; i++)

2. arr[i] = arr[elements_no - i];

3. arr[elements_no - i] = x;

The correction of the above lines are:

1. for (i = 0; i <= elements_no/2; i++)

2. arr[i] = arr[elements_no - i-1];

3. arr[elements_no - i-1] = x;

Explanation:

It should be noted that the code end up not reversing the array. This happens because the programmer iterates through all the array elements.

i.e.

1. for (i = 0; i <= elements_no; i++)

This will result in the original array.

To solve this problem, the iteration has to stop at the middle element and the correction is:

1. for (i = 0; i <= elements_no/2; i++)

Also, to swap the individual elements 1 has to be subtracted from each array index. So, the following lines:

2. arr[i] = arr[elements_no - i];

3. arr[elements_no - i] = x;

is corrected to:

2. arr[i] = arr[elements_no - i-1];

3. arr[elements_no - i-1] = x;

See attachment for complete corrections

a variable of array type holds a reference of object

array are commonly used in computer program to organize data so that a related set of values

array are using zero base indexing it start with 0.

all component of array have same type, two different types doesn't use in single array

if array are store 10 quantities its index value varies from 0 to 9.

it stores 1st quantity value in index value 0 and this process will same till index value 9.

it can either be 2. or 4. : ) tell me if i'm wrong or right
