C++ coding lab task

Write a Program to calculate:
1) Kinetic Energy
2) Potential Energy
3) Total Energy
Requirement for this assignment includes the use of at least 3 Programmer Defined Functions, with at least one of the functions using PASS BY REFERENCE Parameters. 
Please DO NOT  use global variables unless specified.
But can use global constant to store “acceleration due to gravity”.
 
Formula & Explanation for these three are as follows:

For Kinetic Energy:
Mass is in “kg”
Velocity is in “m/s”
 
For Potential Energy:
Mass is in “kg”
Height is in “m”
Gravitational Acceleration is going to be considered as constant for the purpose of the program ie 9.81
