- (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(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_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_forwardCorrectFormation Create a program and locally declare in main fname and Iname and completeName. Ask the user for their first and last name. Put the values into fname and Iname. You will create a function that is called as followed. joinNames( fname, Iname, completeName ); You will pass the first name array, the last name array, and the array that will contain the complete name. The function named joinNames should put the first and last names together in completeName. Make sure that the first and last names begin with capital letters, and that ll others are lower case. Display the final combined name. O X Please enter your first name:chuck wagon Please enter your last name:The complete name is Chuck Wagon Process returned e (@x) execution time : 5.192 5 Press any key to continue.arrow_forwardMovie Data Write a program that will be used to gather statistical data about the number of movies college students see in a month. The program should ask the user how many students were surveyed and dynamically allocate an array of that size. The program then should allow the user to enter the number of movies each student has seen. It should then sort the scores and calculate the average. Modularity: Main: The main function should accept the number of students from the user and dynamically create an array large enough to contain number of movies watched for each student. Input validation: The number of students should be a positive integer. Print the average and free the allocated array when complete. Get the data: This function should get the number of movies watched by each college student. Input validation: The number of movies should be a positive integer. Sort the data: This function should sort the array in ascending order. Note you may use the Standard Template Library sort…arrow_forward
- JAVA CODE PLEASE Functions with 1D Arrays Practice II by CodeChum Admin Create a program that asks the user for the size of an integer array and the elements of the array. Then, create a function with the following details: Parameters: An integer array The size of the integer array Return type - int Return value - the maximum value of the integer array Call the function you created in the main and pass the integer array and its size to it. Make sure to store the return value in a variable so you could print it afterwards. Input 1. First line contains the size of the array 2. Succeeding lines are the elements of an array Output Enter·size·of·array:·5 Enter·element·1:·1 Enter·element·2:·2 Enter·element·3:·3 Enter·element·4:·4 Enter·element·5:·5 Maximum·element:·5 Score: 0/10arrow_forwardTo receive an array argument, a function's parameter list must specify that the function expects to receive an array. The size of the array is not required between the array brackets. Select one: True Falsearrow_forwardUse C++ programing language Write a modular program that analyzes a year’s worth of rainfall data. In addition to main, the program should have a getData function that accepts the total rainfall for each of 12 months from the user and stores it in an array holding double numbers. It should also have four value-returning functions that compute and return to main the totalRainfall, averageRainfall, driestMonth, and wettestMonth. These last two functions return the number of the month with the lowest and highest rainfall amounts, not the amount of rain that fell those months. Notice that this month number can be used to obtain the amount of rain that fell those months. This information should be used either by main or by a displayReport function called by main to print a summary rainfall report similar to the following: 2019 Rain Report for Springdale County Total rainfall: 23.19 inches Average monthly rainfall: 1.93 inchesarrow_forward
- 1- Write a user-defined function that accepts an array of integers. The function should generate the percentage each value in the array is of the total of all array values. Store the % value in another array. That array should also be declared as a formal parameter of the function. 2- In the main function, create a prompt that asks the user for inputs to the array. Ask the user to enter up to 20 values, and type -1 when done. (-1 is the sentinel value). It marks the end of the array. A user can put in any number of variables up to 20 (20 is the size of the array, it could be partially filled). 3- Display a table like the following example, showing each data value and what percentage each value is of the total of all array values. Do this by invoking the function in part 1.arrow_forwardin c++ In statistics, the mode of a set of values is the value that occurs most often or with the greatest frequency. Write a function that accepts as arguments the following: A) An array of integers B) An integer that indicates the number of elements in the array The function should determine the mode of the array. That is, it should determine which value in the array occurs most often. The mode is the value the function should return. If the array has no mode (none of the values occur more than once), the function should return −1. (Assume the array will always contain nonnegative values.) Demonstrate your pointer prowess by using pointer notation instead of array notation in this function.arrow_forwardPHP Write a modeMaker function Write a function modeMaker() that forms a closure such that the function it returns can be used with your reduce() function above to find the mode of an array. The mode of an array is the value that appears the most frequently (so in the $arr above, the mode is 5). To do this, you will need an array called $seen that keeps the count of times an element has been examined At the end of the reduce function, the $seen array should look like the following for the $arr above: Array ( [10] => 1 [5] => 3 [3] => 1 [1] => 1 [2] => 1 [7] => 1 ) Note that the closure you generate should always be returning the current mode for what it has seen so far (so it will either be the current mode, or the new element passed in). The following is a start for modeMaker: function modeMaker() { $seen = array(); return function($current, $new) use (&$seen) { // your code that uses $seen goes here }; } $mode =…arrow_forward
