Concept explainers
Array of structures:
In C++, it is possible to create an array of structure; it is used to store a group of records contains multiple data members of various data type. A single array of structure can replace many arrays of regular type variable.
- Array of structures can be defined like normal array.
The structure array is declared through the following format:
struct_name variable[size];
Consider the following array definition:
//Declaration of structure array
Car values[5];
- In the above example, “Car” represents the structure type of the array, “values[]” is the array name, and the number inside the brackets is the size declaratory of the array.
Subscript of an array:
In C++, array elements can be accessed using a subscript. In an array, each element assigned with the unique number, which is specified inside the brackets, is referred as a subscript.
- By default, structure members are defined as “public”. Hence structure members can be accessed by place the dot operator (.) and member name after the array subscript.
Example:
//Assign the value for model member of values[2].
values[2].model = "New"
- In above statement, the value “New” is assigned in the third element of the “values” array for model member.

- The code to traverse a twodimensional array using the Do...Loop statement requires two loops. True or False?arrow_forwardCheckpoint 1: Create an array and initialize all the elements to 0. Write a loop that will display cach elements position and value. That is show "my_arrayf3] = 0" for each element as output where 3 is the 4th clement in the array and 0 is value of that element. Now assign random values to cach element. You can use the function rand() which will return an integer. This function will return a number between 0 and RAND MAX = 32767. You can mod the value retumed by rand() by 16 to fit the range 0 to 15. For debugging, the seed is the same until you change it. This means all the output numbers will be the same as in the sample output. Checkpoint 2: We want to calculate some base statistics for the array. You can access each element of the array by using "my array[i]" where i is the index of the array. You may use a loop to run through each index to cover the entire array. We will start finding statistics for this array by finding the maximum value, minimum value, and sum of all values in…arrow_forwardCreate all possible outcomesarrow_forward
- Create class named student_names that prompts the user to enter three names of three students, puts them in an Array, utilize do - while loop to read the names in the array and prints all the of themarrow_forwardQuestion 1 Write a program that declares an array of 100 doubles. The program asks the user to enter a number N between 100, and then: initializes the first N elements of the array to random numbers between 1 and 100. calculates the average of these numbers and displays it. A final loop displays the elements of the array, each on a line, with an indication as to whether that number is lower or higher than the average. For example, if the numbers generated are 5, 28, 3, 8, 15, 7, 22, 6, 1, 4, then the program will print: Average = 9.9 5 28 3 8 15 7 22 6 1 4 11 11 11 -- 11 11 1- —— 11 lower than average higher than average lower than average lower than average higher than average lower than average higher than average lower than average lower than average lower than averagearrow_forwardYou can copy all elements of one array into one another with an assignment statement. True or Falsearrow_forward
- Date Printer Write a program that reads a char array from the user containinga date in the form mm/dd/yyyy. It should print the date in the form March 12, 2014.arrow_forwardConstruct an application named BookArray in which you create an array that holds 10 Book objects (5 Fiction objects and 5 NonFiction objects). Using a for loop, display the details about the 10 book objects.arrow_forward# Declare a named constant for array size here. MAX_AVERAGES = 8 # Declare array here. # Write a loop to get batting averages from user and assign to array. averageString = input("Enter a batting average: ") battingAverage = float(averageString) # Assign value to array. # Assign the first element in the array to be the minimum and the maximum. minAverage = averages[0] maxAverage = averages[0] # Start out your total with the value of the first element in the array. total = averages[0] # Write a loop here to access array values starting with averages[1] # Within the loop test for minimum and maximum batting averages. # Also accumulate a total of all batting averages. # Calculate the average of the 8 batting averages. # Print the batting averages stored in the averages array. # Print the maximum batting average, minimum batting average, and average batting average.

- 2. Creates an array of Triangle type of size 10. Prompts the user to enter the index of the array, then displays the area of corresponding element value. If the specified index is out of bounds, display the message Out of Bounds.arrow_forwardAskForNumbers Declare an integer array locally with the size of 200. Create a program that asks the user how many numbers the have. Use your getChoice() function from before. Make sure it does not exceed 200 as the locally declared array has the size of 200 Use a for loop and ask the user to enter each value that must be stored in the array Use a second loop to display each number, and also determine the average of all values in the array After the for loop, display the average of all numbers. This program will let you enter a list of numbers into an array. It will then display all of the numbers, and finally display the average of all numbers. How many numbers would you like to enter?5 Please enter a number: 22 Please enter a number: 33 Please enter a number:44 Please enter a number: 55 Please enter a number: 66 lumber 1 is 22 lumber 2 is 33 lumber 3 is 44 lumber 4 is 55 lumber 5 is 66 The average is 44arrow_forwardin java when you use an enhanced for loop with an array, you don’t need to use a/an ________________ variable to iterate through the elements of the array.arrow_forward
