For C++, why is it that reference values can change when given to a function? I understand that if you make a const reference parameter like: double functionname(const point& p1) then the function cannot attempt to make a change to the parameter.

I am learning c++, and I get confused. I meet three questions, and one is asking to write a function header for a function named distance; the second question is to write the prototype for a function named distance, and the third question is to write a function call for a function named distance. I am wondering how to write different functions for these three questions? What are the differences between them? I am so confused.

Write a value function in a C++ program that has two double parameters, calculates their difference, and returns the absolute value of the difference?

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.

Using C++ Using your own creativity, make a set of function templates that have these features: This function must return a value. A function template with 1 template parameter, T. And, any other parameters you want. A function template with 2 template parameters, T1 and T2. And, any other parameters you want Within main (): Call your template functions and demonstrate how they work. Construct objects and show off your amazing programming skills!

In C/C++, Function overloading is the process of creating several functions that have exactly the same name. In order to overload successfully, each function must have: A. A different parameter list B. A different number of parameters and a different return type C. An integer on the end of the function name, such as func1()and func2() D. Either A or B E. Both A and C

Using C++ Using your own creativity, make a set of function templates that have these features: This function must return a value. A function template with 1 template parameter, T. And, any other parameters you want. and then another function template but this time with 2 template parameters, T1 and T2. And, any other parameters you want.

C++ Write the defnition of the function int computeProd() with parameters that receives as arguments two integer values computes their produc and returns it to the celing function.
