A closer look at functions - C++

C option: (The best grade is a 79%) Write a program to calculate the cost and time it takes to fill a swimming pool . Inputs: Length, Width, and Depth of the pool (This is a gross simplification, since pools are not really rectangular cubes.) Fill rate of the pool in Gallons per minute Calculation functions Write a function to calculate the total cubic feet (Length x Width x Depth) and return the cubic feet. Inputs: Write a function to calculate the number of gallons 1 cubic foot- 7.48051948 US gallons (Create a constant to hold the conversion factor.) Input: Cubic Feet Write a function to calculate the cost to fill the pool as follows o Length, Width, and Depth Return cubic feet o Return Gallons o Calculate 1000's of gallons by dividing the total gallons by 1000 and putting the result in an integer variable Use the following table to generate the cost Monthly Usage)Monthly Rate) Input: Gallons Return Cost to 3,000 gallons $15.50 2.90 per thousand .Call your functions from main0 Outputs bove the 3000 If there is an xcess above 3,000 gallons plus $15.50 (ie 15.50 +2.90 * # . allons o Total cubic feet o Total gallons o Cost o Time to fill in minutes f thousand gallons r 3 thousand A option: (The best grade is a 100%) Note: No B option on this one Combine the functions to calculate the cubic feet and number of gallon. . o Inputs to the function: Length, Width, Depth o Outputs (via reference variables): Cubic Feet, Gallons Example Prototype void PoolSize(float Length, float Width, float Depth, float &CubicFeet, float &Gallons); Write a function that calculate the time to fill as follows o Inputs to the function: Gallons o Outputs (via reference variables): Hours and Minutes Example Prototype void FillTime(float Gallons, float FillRate, ,float &Hours, float &Minutes); Turn in Program listing of your source code, ZIP and screen prints of the following run: Length 25 Width 12 Depth 8 Fill Rate 10 gallons a minute
