You cannot use the _________ operator to copy data from one array to another in a single statement.

The following code totals the values in two arrays: numberArray1 and numberArray2. Both arrays have 25 elements. Will the code print the correct sum of values for both arrays? Why or why not? int total = 0; // Accumulator int count; // Loop counter // Calculate and display the total of the first array. for (count = 0; count < 24; count++) total += numberArray1[count]; cout << "The total for numberArray1 is " << total << endl; // Calculate and display the total of the second array. for (count = 0; count < 24; count++) total += numberArray2[count]; cout << "The total for numberArray2 is " << total << endl;

Consider the following array definition: int values[5] = { 4, 7, 6, 8, 2 }; What does each of the following statements display? cout << values[4] << endl; __________ cout << (values[2] + values[3]) << endl; __________ cout << ++values[1] << endl; __________
