using c++ write a program Make an integer array of size 20 for storing marks. Input in array. (20) Make following functions. int countpass(int marks[ ]). This function will receive array and return count of passed students. passing criteria is atleast 50 marks int * passedstudent(int marks[ ]). This function will return an array of passed students. You can use countpass function to know size of passed student array.

In statistics the mode of a set of values is the value that occurs most often. Write a program that determines how many pieces of pie most people eat in a year. Set up an integer array that can hold responses from 30 people. For each person, enter the number of pieces they say they eat in a year. Then write a function that ﬁnds the mode of these 30 values. This will be the number of pie slices eaten by the most people. The function that ﬁnds and returns the mode should accept two arguments, an array of integers, and a value indicating how many elements are in the array.
In C++ please ! Write a Program that: Initializes an interger array size of 10 with random intergers in range [10,30]. Use a function named 'initialized_array' to acheive that. Determine if all array elements are distinct from each other or not.Use boolean function named 'distinct_elements' to achieve that function 'distinct elements, if the elements in the array are duplicate print out, elements are duplicate if not print out array
Write a c++ program for an atm machine. Use an array with maximum number of accounts to be 100. ATM machine performs the following function: 1. create account An account must have a unique id and 4 digit number pin. eg id = "yo" pin = "4444". if the given unique id is already taken ask the user to enter another unique id. also make sure the pin contains numbers only. 2. Login prompt the user to enter id and pin. incase any of the two is incorrect, print an error message saying incorrect pin or id. 3. withdraw withdraw money from the available balance in the account. make sure the user is logged in. 4. deposit deposit money in the account and update the balance. again make sure user is logged in. 5. pin code change. this allows the user to change their pin. ask for previous pin code and then ask to enter new pin code. 6. balance print the balance that is in the account. 7. logout. logout from the system.
In C programming languge: Write a function that takes an array of ints, and the size of the array – another int. It also returns a double. Call this one ‘average.’ Return a double that is the average of the values in the array. Demonstrate that it works by finding the average of an array with these values {78, 90, 56, 99, 88, 68, 92}
An instructor gives a multiple choice test which consists of 5 questions, each of which is answered by a choice of one of the numbers one to five. Write a program to call function TEST that accepts as input student name and the set of their test answers as one dimensional array. The program should grade the test. If the student choice is 1 give 1 point. If the choice is 2, give 2 points. 3 points if choice answer is 3 and 4 pints for answer 4 and choice 5 is 5 points. Otherwise no point is given to other choices. Print out the average score of the student in the test.SAMPLE RUN 1:INPUT : Enter student name : LYNNEEnter Answer # 1? 2Enter Answer # 2? 3Enter Answer # 3? 5Enter Answer # 4? 5Enter Answer # 5? 4OUTPUT : LYNNE, your total score is 19 and your average score is 3.8.SAMPLE RUN 2:INPUT : Enter student name : ROSEEnter Answer # 1? 2Enter Answer # 2? 3Enter Answer # 3? 767Enter Answer # 4? 5Enter Answer # 5? 4OUTPUT : ROSE, your total score is 14 and your average score is 2.8.
By using C++ program Write an application that solves a system of linear equations. Have the user input the coefficients of the two lines. Remember that the definition of a line is: Ax + By = C. You can use any method you wish to solve. The program should output the intersection of the two lines if they do indeed intersect, indicate if the two lines are parallel, or if they are the same line. Note: use an Array.
Using C language Write a function that determines standartdeviation of float array. The function takes dataset as afloat array parameter!! And it also return result as afloat.(Clue: calculate average first) Definations: in the image σ = standard deviationxi = each value of dataset? (with a bar over it) = the arithmetic mean of the data(This symbol will be indicated as average of dataset)N = the total number of data points(if you need square root of some number you can use sqrtfunction in math.h library. Usage example: a=sqrt(b);which means “a” is equal to square root of “b”)
Using c++ 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 inches The least rain fell in January with 0.24 inches. The most rain fell in April with…
In statistics, the mode of a set of values is the value that occurs most often or with the greatestfrequency. Write a function that accepts as arguments the following:A. An array of integersB. An integer that indicates the number of elements in the arrayThe function should determine the mode of the array. That is, it should determine which valuein the array occurs most often. The mode is the value the function should return. If the arrayhas no mode (none of the values occur more than once), the function should return −1.Demonstrate your pointer process by using pointer notation instead of array notation in thisfunction.
In C++ language For number 2 through 4 create an integer array with 100 randomly generated values between 0 and 99; pass this array into all subsequent functions. Place code in your main to call all the methods and demonstrate they work correctly. Using just the at, length, and substr string methods and the + (concatenate) operator, write a function that accepts a string s, a start position p, and a length l, and returns a subset of s with the characters starting at position p for a length of l removed. Don’t forget that strings start at position 0. Thus (“abcdefghijk”, 2, 4) returns “abghijk” Create a function that accepts the integer array described above returns the standard deviation of the values in a. The standard deviation is a statistical measure of the average distance each value in an array is from the mean. To calculate the standard deviation, you first call a second mean function that you need to write (do not use a built in gadget. Then sum the square of the difference…
Write a function that displays an n-by-n matrix using the following header: void printMatrix(int n)Each element is 0 or 1, which is generated randomly. Write a test program that prompts the user to enter n and displays an n-by-n matrix.
Write a program that will read the monthly salary of 10 employees and then calculates the income tax (i.e, 10% of the salary) and net salary. Hence you have to declare an array salary[10][3]. Your program should have 4 functions. The first function will be used to read monthly salary of 10 employees and put it in the first column of the array. The second function will be used to calculate the income tax for each employee and then store it in the second column of the array. The third function will be used to calculate the net salary of each employee and store it in the third column of the array. Finally, the fourth function will be used to display the gross salary, income tax and net salary for each employee. You must pass the array as reference in each function you used.
