C language The program should allow users to add, subtract, multiply, and divide fractions. The program should display a menu and prompt the user for a mathematical operation, until they enter 5 to exit. The menu should give the user the option to add, subtract, multiply or divide fractions, or exit. After the user chooses their option, they should be prompted to input two fractions. The result of the arithmetic should then be displayed to the screen. Requirements main()Functionality: This main function should prompt the user for a menu option until they enter 5. If the user doesn't choose Option 5 to end the program, it should get two fractions from the user. It should decide, based on the menu option which actions to perform on the fractions. Option 1 adds the two fractions together. Option 2 subtracts the first fraction from the second. Option 3 multiplies the two fractions together. Option 4 divides the first fraction by the second one. In addition to the main functions, your…

Hands-On Activity 4-4 BuzzButtons is a novelty item company manufacturing personalized lapel buttons that buzz randomly. The buttons are marketed as a conversation starter, and the company's slogan is "It starts the buzz!" The owner is promoting his buttons by offering them at 99 cents each. He wants you to design a program asking the user for his or her name for the button, an e-mail address, and the number of buttons to order. The program should then add a 6% sales tax and a flat shipping rate of $2.00. The program displays the information the user enters as well as the button price total, sales tax amount, shipping amount, and order total. The company contacts the user by e-mail later for shipping address information. Using pseudocode, design an algorithm that asks the user for the number of fixed-price items to order, adds sales tax and flat-rate ship- ping, and displays the result. Save your pseudocode file in Notepad as buzzButtons.txt.
