- (Statistics) Write a program that includes two functions named calcavg() and variance(). The calcavg() function should calculate and return the average of values stored in an array named testvals. The array should be declared in main() and include the values 89, 95, 72, 83, 99, 54, 86, 75, 92, 73, 79, 75, 82, and 73. The variance() function should calculate and return the variance of the data. The variance is obtained by subtracting the average from each value in testvals, squaring the values obtained, adding them, and dividing by the number of elements in testvals. The values returned from calcavg() and variance() should be displayed by using cout statements in main().arrow_forward(Electrical eng.) Write a program that specifies three one-dimensional arrays named current, resistance, and volts. Each array should be capable of holding 10 elements. Using a for loop, input values for the current and resistance arrays. The entries in the volts array should be the product of the corresponding values in the current and resistance arrays (sovolts[i]=current[i]resistance[i]). After all the data has been entered, display the following output, with the appropriate value under each column heading: CurrentResistance Voltsarrow_forward(Electrical eng.) Write a program that declares three one-dimensional arrays named volts, current, and resistance. Each array should be declared in main() and be capable of holding 10 double-precision numbers. The numbers to store in current are 10.62, 14.89, 13.21, 16.55, 18.62, 9.47, 6.58, 18.32, 12.15, and 3.98. The numbers to store in resistance are 4, 8.5, 6, 7.35, 9, 15.3, 3, 5.4, 2.9, and 4.8. Your program should pass these three arrays to a function named calc_volts(), which should calculate elements in the volts array as the product of the corresponding elements in the current and resistance arrays (for example ,volts[1]=current[1]resistance[1]). After calc_volts() has passed values to the volts array, the values in the array should be displayed from inside main().arrow_forward
- Write a statement that declares a procedure-level one-dimensional array named intorders. The array should contain 15 elements.arrow_forward(Data processing) A bank’s customer records are to be stored in a file and read into a set of arrays so that a customer’s record can be accessed randomly by account number. Create the file by entering five customer records, with each record consisting of an integer account number (starting with account number 1000), a first name (maximum of 10 characters), a last name (maximum of 15 characters), and a double-precision number for the account balance. After the file is created, write a C++ program that requests a user-input account number and displays the corresponding name and account balance from the file.arrow_forwardpseudo code in problem solving and logic and flowchartTotal Sales (Arrays) Design a program that asks the user to enter a store’s sales for each day of the week (for one week). The amounts should be stored in an array. Use a loop to calculate the total sales for the week and display the result. Guideline: Rename the variables with your student number (e.g., amount_697) Use an array to solve the above problem Add comments with your name/student number Comment your codearrow_forward
- C#/Csharp program Tyarrow_forwardPseudocode for the student grade calculator program, please Create a program to enter grades and calculate averages and letter grades. Need a class which will contain: Student Name Student Id Student Grades (an array of 3 grades) A constructor that clears the student data (use -1 for unset grades) Get functions for items a, b, and c, average, and letter grade Set functions for items a, n, and c Note that the get and set functions for Student grades need an argument for the grade index. Need another class which will contain: An Array of Students (1 above) A count of number of students in use You need to create a menu interface that allows you to: Add new students Enter test grades Display all the students with their names, ids, test grades, average, and letter grade Exit the program Add comments and use proper indentation. Nice Features: I would like that system to accept a student with no grades, then later add one or more grades, and when all grades are entered, calculate the…arrow_forwardC++ Programmingarrow_forward
- Weather Statistics": Problem Statement: Write a program that uses a structure to store the following weather data for a particular month: Total Rainfall High Temperature Low Temperature Average Temperature The program should have an array of 12 structures to hold weather data for an entire year. When the program runs, it should ask the user to enter data for each month. (The average temperature should be calculated.) Once the data are entered for all the months, the program should calculate and display the average monthly rainfall, the total rainfall for the year, the highest and lowest temperatures for the year (and the months they occurred in), and the average of all the monthly average temperatures. Input Validation: Only accept temperatures within the range between -100 and +140 degrees Fahrenheit.arrow_forward2. Lottery Number Generator Design a program that generates a 7-digit lottery number. The program should have an Integer array with 7 elements. Write a loop that steps through the array, ran- domly generating a number in the range of 0 through 9 for each element. (Use the random function that was discussed in Chapter 6.) Then write another loop that displays the contents of the array.arrow_forwardAssignment #1 Instructions: Assigning Seats - planeseats Through this programming assignment, the students will learn to do the following: 1. Know how to use a Makefile. 2. Perform basic C commands. 3. Use arrays, integers and strings. This assignment asks the user to write a program to assign seats in an airplane. There will be 12 seats on the plane, 4 in first class and 8 in economy. • The program should display the following menu for the user: Please type 1 for "first class" Please type 2 for "economy" Please type 0 to quit • If the user types 1 then the user should be assigned a seat in first class. If the user types 2 then the user should be assigned a seat in economy. • If the user types O for a sentinel value the program should ext with a O return code. • The program should then print a line indicating the seat the person was assigned. This would be like a boarding pass. • The program should not assign a seat that has already been assigned. If all seats in the desired section…arrow_forward
