Correct the following code so that it correctly sets the value of each element of myList to the index of the element. int myList[10]; for (int i = 1; i <= 10; i--) myList[i] = [i];

Correct the following code so that it correctly initializes and outputs the elements of the array myList. int myList[10]; for (int i = 1; i <= 10; i++) cin >> myList; for (int i = 1; i <= 10; i++) cout << myList[i] << " "; cout << endl;

What is array index out of bounds? Does C++ check for array indices within bounds?

Suppose that scores is an array of 10 components of type double, and: scores = {2.5, 3.9, 4.8, 6.2, 6.2, 7.4, 7.9, 8.5, 8.5, 9.9} The following is supposed to ensure that the elements of scores are in nondecreasing order. However, there are errors in the code. Find and correct the errors. for (int i = 1; i <= 10; i++) if (scores[i] >= scores[i + 1]) cout << i << " and " << (i + 1) << " elements of scores are out of order." << endl;

Write C++ statements to define and initialize the following arrays. a. Array heights of 10 components of type double. Initialize this array to the following values: 5.2, 6.3, 5.8, 4.9, 5.2, 5.7, 6.7, 7.1, 5.10, 6.0. b. Array weights of 7 components of type int. Initialize this array to the following values: 120, 125, 137, 140, 150, 180, 210. c. Array specialSymbols of type char. Initialize this array to the following values: '$', '#', '%', '@', '&', '! ', '^'. d. Array seasons of 4 components of type string. Initialize this array to the following values: "fall", "winter", "spring", "summer".

Determine whether the following array declarations are valid. If a declaration is valid, determine the size of the array. a. int list[] = {18, 13, 14, 16}; b. int x[10] = {1, 7, 5, 3, 2, 8}; c. double y[4] = {2.0, 5.0, 8.0, 11.0, 14.0}; d. double lengths[] = {8.2, 3.9, 6.4, 5.7, 7.3}; e. int list[7] = {12, 13, , 14, 16, , 8}; f. string names[8] = {"John","Lisa", "Chris", "Katie"};

Suppose that you have the following declaration: int list[7] = {6, 10, 14, 18, 22}; If this declaration is valid, what is stored in each components of list

Consider the following declaration: int list[] = {3, 8, 10, 13, 6, 11}; a. Write a C++ code that will output the value stored in each component of list. b. Write a C++ code that will set the values of the first five components of list as follows: The value of the ith component is the value of the ith component minus three times the value of the (i+1)th component.
