For a particular illness a patient should take 3 drugs every day: Drug A, drug B and drug C. According to his age and his gender the following table describes the necessary quantity Write down a program that allows to calculate and print the quantities of the three drugs if a user enters his age and his gender. Age range A B age = 60 Figure 1: How to calculate drug quantity 30 mg 40 mg 35 mg 2A mg 4A mg 3A mg 20+B - 1.5K 40 + 2B - 3K 30 + B - 2.5K K= A/2 for Male ('M"), Al 3 for Female ('F') Write 3 functions and a main function. Do not use any library other than stdio. Function 1: (20 pts) Function name: CalculateA Function parameter: 1 int parameter named "age" Return type: double See Figure 1 to figure out what it does. Function 2: (20 pts) Function name: CalculateB Function parameter 1 int parameter named "age" Return type: double See Figure 1 to figure out what it does. Function 3: (40 pts) Function name: Calculatec Function parameter 1 int parameter named "age" and 1 char parameter named "gender" Return type: double See Figure 1 to figure out what it does. The main function: Ask 2 values from the user: age (int) and gender (char). (5 pts) Call the functions to calculate the quantity of each drug the patient should take depending on his age and gender. (10 pts) Print the quantity of each drug as in the examples below. (5 pts) Do the printf and scanf operations only in the main function.
