Examine each of the following program segments carefully. Determine what is printed from each program. There are no intentional errors. 1. int array[] = {1, 2, 3, 4, 5}; for (int i = 0; i < 5; i++) cout << array[i]*5 << “ “; Output _________________________________ 2. int *iptr; iptr = new int[5]; for (int count = 0; count < 5; count++) iptr[count] = count+1; cout << *iptr << endl; Output _________________________________ 3. int x = 50, y = 60,...

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; marks is an integer array with 20 elements. Write a for loop that prints each element of the array. The arrays numberArray 1 and numberArray2 have 100 elements. Write code that copies the values in numberArrayl to numberArray2.
What is the output of the following code? int num = 17; //Line 1 double gpa = 3.85; //Line 2 bool done; //Line 3 done = (num == static_cast<int>( (2 * gpa + 9.3))); //Line 4 cout << "The value of done is: "<< done << endl; //Line 5
