Variables and Constant

Constants and variables are widely used in mathematical equations and expressions. They are also commonly found in the domain of programming, where each language has its own way to differentiate between a constant and a variable. Since they have all sorts of applications, knowing their differences is a good place to start.

A retail company assigns a $5000 store bonus if monthly sales are more than $100,000; otherwise a $500 store bonus is awarded. Additionally, they are doing away with the previous day off program and now using a percent of sales increase to determine if employees get individual bonuses. If sales increased by at least 4% then all employees get a $50 bonus. If they do not, then individual bonuses are 0. Step 7: The final step in completing the pseudocode is to call all the modules with the proper arguments. Complete the missing lines.

Prime factors of an integer $ n $ are a set of prime numbers that can be multiplied together to obtain $ n $. Write a proHide Transcribed Text Prime factors of an integernare a set of prime numbers that can be multiplied together to obtainn. Write a program that asks the user to enter a number and displays the prime factors ordered from smallest to largest. If the number entered by the user is less than 2 then there are no prime factors and the message "No prime factors" should be displayed. The following algorithm can be used to discover the prime factors: - initialize factor to 2 - while factor is less than or equal tondo: ifnis evenly divisible by factor then - conclude that factor is a factor ofn- dividenby factor using floor division else: - increase factor by 1 Adapt the algorithm so it can be used to print out the prime factors of a number.
