Qn1: You are asked to write a simple C program that will accept an integer value in the range of 5-95 and as a multiple of 5 representing the number of cents to give to a customer in their change. The program should calculate how many coins of each denomination and display this to the user. Valid coin values are 50, 20, 10 and 5. Your solution (program and algorithm) should be modular in nature. This requires the submission of a high-level algorithm and suitable decompositions of each step. Note that for this problem the principle of code reuse is particularly important and a significant number of marks are allocated to this. You should attempt to design your solution such that it consists of a relatively small number of functions that are as general in design as possible and you should have one function in particular that can be reused (called repeatedly) in order to solve the majority of the problem. If you find that you have developed a large number of functions which each performs…

C++ CODE ONLY: Write a program that takes as input five numbers and outputs the mean (average) and standard deviation of the numbers. If the numbers are X₁, X2, X3, X4, and x5, then the mean is X = (X1 + X2 + X3 + x4 + x5 ) / 5 and the standard deviation is: (x₁−x)²+ (x₂-x)²+ (x¸¯x)²+(x¸−x)²+(x¸¯x)² S = 5 Your program must contain at least the following functions: 1. a function that calculates and returns the mean; and, 2. a function that calculates the print standard deviation. Input 1.5 integers Output Enter five numbers: 2 3 9 10 11 The mean is 7.00. The standard deviation is 3.742. Enter five numbers: 7 7 8 9 11 The mean is 8.40. The standard deviation is 1.497.

C++ - No library functions like atoi Write a machine language program to output your first name on the output device. Submit your "machine code" followed by a 'zz.' An example of the machine code to output "hello" is shown below. This is an example of what a machine language submission would look like: 50 00 48 50 00 65 50 00 6c 50 00 6c 50 00 6f 00 zz

Write C assignment statements for the following: a. Assign a value of 0 to a variable called between if n is less than -k or greater than +k; otherwise, assign 1. b. Assign a value of 1 to a variable called divisor if digit is a divisor of num; otherwise, assign a value of 0. c. Assign a value of 1 to a variable called lowercase if ch is a lowercase letter; otherwise, assign a value of 0.

In C++, write a program that calculates and prints a monthly paycheck for an employee. The net pay is calculated after taking the following deductions from the employee's gross salary: Federal Income Tax: 17.5% State Tax: 9.1% Social Security Tax: 6.2% Medicare Tax: 1.45% Retirement Plan: 9.29% Health Insurance: $51.48 Life Insurance: $3.71 Your program will prompt the user to input the employee ID, the employee name, and the employee's monthly gross salary. The program will calculate the deductions listed above, along with the percentage of take home pay (defined as the net pay divided by the gross salary). After calculating each deduction and percentage, the output will be printed to the screen (see example output below). Requirements All decimal numbers must be formatted to 2 decimal places. Ask for the employee's ID first, then full name (can include spaces), then the salary. The prompt to enter the salary must include the employee name. The employee ID MUST be…
