Write a C++ function: int cube(int ); This function takes an Integer parameter and return the cube of that number.

In C++: Write a function which will find the average of all elements of the sequence: {2, 4, 6, 8, 10, 12}.  Use call by reference, and return the average as the function's return value.

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 reference parameter used to pass back the result of this formula: 25.0*num+37.0. DO NOT do any read or write operations in the function. Declare local variables as appropriate.

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
