C++ Write a void function that has two parameters: a value parameter called num that receives a floating point number from the calling function and a floating point reference parameter called result. The functions should do this calculation: 25.0 * num + 37 and store the answer in result. Do not do any read or write operations in the function.

done in c++ Program Specifications: Write a program that asks for a user's name and age, finds the ticket price based on the age, and prints out the user's name, age, and ticket price. The program must define the following 3 functions and call them in the main function. Create a function called getName that takes in no arguments and returns the name of the user. Create a function called getAge that takes in the argument age and uses pass-by-reference to set the age of the user. Ensure that the user cannot put in an age that is negative or greater than 100. Create a function called printTicket that takes in the user's name and age and does the following ○ If they are less than or equal to 13 years old set ticket_Price to 9.99. ○ If their age is greater than 13 and less than 65, set ticket_Price to 19.99. ○ If their age is greater than or equal to 65, set ticket_Price to 12.99. ○ Output to the console the user's name, age and ticket price.

Set-up and implementation code for a void function MaxYou are not required to write a complete C++ program but must write and submit just your responses to the four specific function related questions below: QC1: Write the heading for a void function called Max that has three intparameters: num1, num2 and greatest. The first two parameters receive data from the caller, and greatest is used to return a value as a reference parameter. Document the data flow of the parameters with appropriate comments*. QC2: Write the function prototype for the function in QC1. QC3: Write the function definition of the function in QC1 so that it returns the greatest of the two input parameters via greatest, a reference parameter. QC4: Add comments to the function definition* you wrote in QC3 that also states its precondition and postcondition.
