Partial initialization of an array:
The C++ program allows the user to initialize the elements of an array while creating the array; the initialization list stores the value in an array in the specific order as they are initialized.
- Additionally, while initializing the array it is no need to initialize all the elements of an array; the uninitialized elements of the array will be set to “0” by default.
- For the “string” array, it stores the empty strings for uninitialized elements.
- If a local array is completely uninitialized, then the elements are stored with the garbage values.
For example:
Consider the following snippet,
// Constant for the array size
const int num_of_days = 6;
// Initialization list
int days[num_of_days] = {1, 2, 3};
In the above example, the sequence of values stored inside the braces and separated with commas is referred as the initialization list.
- The values are stored in the array in below format:
days[0] = 1;
days[1] = 2;
days[2] = 3;
days[3] = 0;
days[4] = 0;
days[5] = 0;
Thus, if an array is partially initialized, then the uninitialized elements will be assigned as “0”.

- Mcq: How do you initialize an array in C? A) int arr(3) = {1,2,3}; B) int arr[3] = {1,2,3};arrow_forwardReverse ArrayWrite a function that accepts an int array and the array’s size as arguments. The function should create a copy of the array, except that the element values should be reversedin the copy. The function should return a pointer to the new array. Demonstrate thefunction in a complete program.arrow_forwardCode for this in C: You have already created an array named NUMBERS with 20cells. You are to initialize all of the cells with odd subscripts to 1 and all of the cells with even subscripts to 2.arrow_forward
- Lotto Program C++Write a program that simulates the Powerball lottery. In Powerball, a ticket is comprised of 5 numbers between 1 and 69 that must be unique, and a Powerball number between 1 and 26. The Powerball does not have to be unique. Hint: You can use an array to represent the 5 unique numbers between 1 and 69, and an integer variable to represent the powerball. The program asks the player if they'd like to select numbers or do a 'quickpick', where the numbers are randomly generated for them. If they opt to select numbers, prompt them to type the numbers in and validate that they are unique (except the powerball), and in the correct range. The program then generates a 'drawing' of 5 unique numbers and a Powerball, and checks it against the user's lotto ticket. It assigns winnings accordingly. Because it is so rare to win the lottery, I suggest hard coding or printing values to when testing the part of the program that assigns winnings.arrow_forwardvar newStaff =new Employee[3]; is used to: Select one: a.
