Homework Answers
// create a new double sized array
int *copy = new int[200];
// copy all elements from a to copy
for (int i = 0; i < 100; ++i) {
copy[i] = a[i];
}
// assign a to this newly created array
a = copy;

Suppose v is an array with 100 int elements. If 100 is assigned to v[100], what happens? Show the code. An array of 1000 integers is declared. What is the largest integer that can be used as an index to the array? Shows the code. Consider the declaration: int v[1]; What is the index of the last element of this array? Declare an array named a of 10 int elements and initialize the elements (starting with the first) to the...

Assume an array list is declared as follows: int list[100] and that all other variables have been appropriately declared. Tell whether each of the following is a valid or invalid statement. If not valid explain why not. cin>>list[3]; cout<<list; x = list[3]+list[4]; list[10] = 3.2; cout<<list[3, 5, 22]; for (int i = 0; i < 100; i ++) cout<<list[i];

Define a two-dimensional int array which has 5 rows and 3 columns. The elements in array is randomly initialized (using Math.random()). Write a method to find the maximum value in this two dimensional array; Write a method to find the average value in the array; Write a method to count how many elements are smaller than average; Write a method to copy contents in a two-dimensional array to a one-dimensional array. The method will return this one-dimensional array. Method is...

Given the prototype: int countPassing(double arr[], int num); Assume that array arr contains num elements with a value. You may assume that the array has been declared with at least num elements. Write the the function definition including the function header for countPassing() so that the number of values greater than or equal to 69.5 in arr[] is returned.
