CP5639 Problem Solving And Programming

Answer:

Functions List

1. getValue(): This function takes an input from the user for the mentioned prompt passed as the parameter and return it back.
2. checkValid(): This function compares the value of the first parameter with all the other parameters passed if it matches any of them.
3. checkValidBetween(): This function compares the value of the first parameter with the other two parameters if it lies in between of the two.
4. calculate(): This function takes up the parameters which are required to calculate the RDCI and then return the RDCI back to the calling function.
5. checkPercent(): This function calculates the percentage of RDCI as calorie intake on the basis of healthy/unhealthy food taken by the user.
6. calculateTemptation(): This function generates a random temptation and the calorie intake for the user and informs the user about the same if there is any tempatation.
7. displayResult(): This function display the message to the user on the basis of the average RDCI and the percentage and the calorie intake by the user in the week.
8. main(): This function defines the flow of the program and is responsible for the desired output.
