In this example, mark[0] is the first element. If the size of an array is n, to access the last element, the n-1 index is used. In this example, mark[4] Suppose the starting address of mark[0] is 2120d. Then, the address of the mark[1] will be 2124d. Similarly, the ...

Then, to calculate the average, we need to first calculate the sum of all elements in the array. This is done using a for-each loop in Java. Finally, we calculate the average by the formula: average = sum of numbers / total count In this case, the total count is given by numArray...
