Create a payroll program to store and calculate the payroll for a small company as follows:Create an array of floats that is 4 rows and 50 columns, with the columns being the number of employeerecords stored in the array.Program parameters are as follows:Create a menu in a function menu and call it with the following options (use a do-while loop):A or a to add employee infoD or d to display employee infoT or t to display total payrollS or s to display the info of all employeesC or c to display the count of employees present in the arrayF or F to delete a recordZ or z to exit programThe information for each employee is: employee number, hours worked, pay rate per hour, taxdeduction.Option A or a:Call the function possible to check and if the index returned is 50 then output a msg saying that thearray is full. If the index returned is less than 50 the call the function add, pass to it the available index asthe third argument and the function will ask the user for one…

You are required to write a program that takes input from the user the marks of his programming fundamentals quizzes in an array. You are required to write the program that caters for 10 students. That means the program asks the user to enter 10 quizzes marks for 10 students (use 2 dimensional array). The program calculates the percentage of all 10 quizzes for each student.Based on the percentage, the program should calculate the grade of each student and store it in a char-one dimensional array. The program should also display the grade of the student on the screen.
The grade is calculated by the formula
percentage>=80 --- grade = A
for percentage >=70 and less than 80 ---------- grade = B
for percentage >=60 and less than 70--------- grade = C
for percentage >=50 and less than 60 ----------grade = D
for percentage less than 50 ----------grade= F
In the end when all the grades have been calculated the program should…
Write C++ statements to do the following:a. Declare an array to hold 7 floating values.b. Assign value 3.3 to the last element in the array.c. Display the sum of the first two elements.d. Write a loop that computes the sum of all elements in the array.e. Write a loop that finds the minimum element in the array.f. Randomly generate an index and display the element at this index in the array.g. Use an array initializer to declare another array with initial values 3.5, 5.5, 4.52, and 5.6.

- (Practice) a. Write output statements using cout that can be used to display values from the first, third, and seventh elements of each array declared in Exercise 2. b. Write a for loop that can be used to display values for the complete array declared in Exercise 2.arrow_forward(Numerical) Using the srand() and rand() C++ library functions, fill an array of 1000 floating-point numbers with random numbers that have been scaled to the range 1 to 100. Then determine and display the number of random numbers having values between 1 and 50 and the number having values greater than 50. What do you expect the output counts to be?arrow_forward(Electrical eng.) a. An engineer has constructed a two-dimensional array of real numbers with three rows and five columns. This array currently contains test voltages of an amplifier. Write a C++ program that interactively inputs 15 array values, and then determines the total number of voltages in these ranges: less than 60, greater than or equal to 60 and less than 70, greater than or equal to 70 and less than 80, greater than or equal to 80 and less than 90, and greater than or equal to 90. b. Entering 15 voltages each time the program written for Exercise 7a runs is cumbersome. What method could be used for initializing the array during the testing phase? c. How might the program you wrote for Exercise 7a be modified to include the case of no voltage being present? That is, what voltage could be used to indicate an invalid voltage, and how would your program have to be modified to exclude counting such a voltage?arrow_forward
- ) Write a complete C++ program that takes 10 integers from the user and stores them in an array by using a for loop. The program should find the sum of the integers at even indexes (including index 0), and then multiply each integer in the array with the sum. The program should then print the new values in the array. Sample run: Enter values: 2 5 1734698 10 Sum of the numbers at even indexes is 20 New values in the array: 40 100 20 140 60 80 120 180 160 200arrow_forwardThis is c programming question. Please use functions for answer.

The program should accept multiple entries and iteratively perform the following operations: (a) ask the item price from the user (b) ask how many items to purchase for a specific item price (c) ask if there are other items to purchase, if yes, repeat the first step, proceed to the next step if otherwise (d) compute and display for the total amount to pay (e) ask for the payment from the user (f) accepts only enough amount of payment, ask another payment if otherwise (g) compute and display changearrow_forwardWrite C++ statements to do the following:i.Declare an empty array DATA to hold 7 double floating values.ii.Assign value 5.7 to the last element in the array.iii.Display the sum of the first two elements without using extra memory variable.iv.Write a while-loop that computes the sum of all elements in the array.v.Write a while-loop that finds the minimum element in the array.vi.Randomly generate an index and display the element at this (randomly generated) index in the array.vii.Use an array initializer to declare another array with initial values 5.78, 12.69, 10.45, and19.0arrow_forwardCorrect my mistake in my C++ code please! Here is the questin and my code is below as well. (Duplicate Elimination with array) Use a one-dimensional array to solve the following problem. Read in 20 numbers, each of which is between 10 and 100, inclusive. As each number is read, validate it and store it in the array only if it isn't a duplicate of a number already read. After reading all the values, display only the unique values that the user entered. Provide for the 'worst case' in which all 20 numbers are different. Use the smallest possible array to solve this problem. Code; #include <iostream> using namespace std; int main(){ int arr[100]={0};int temp,i;for( i=0;i<20;i++){ cout<<"Enter an Integer : "; cin>>temp; arr[temp]++;}for( i=0;i<100;i++) if(arr[i]==1) cout<<i<<" "; return 0;}arrow_forward

(These five numbers can be stored in an array.) The program output should be the output of the average of these five numbers by reading them out of the array and calculating the average and indicating the highest number entered. Please use loops, arrays and conditional statements! Please comment what you did and why.arrow_forwardProgram to sort the array in descending order.
