Answer #1

method signature include return type and name and parameters it takes
return type means the type of value this function is going to return
some of the languages has no return types because their compilers smart enough to detect the
return type based in the function body. Some casting erros we might face not much advantages

    What to do Write a C program that computes Pi with the approximation algorithm that I introduced in class. I want you to write the program in two different ways: The first version will add up the first 28284277 elements of the approximation series in a simple for loop. I ask you to put the code into a function with this signature: float get_pi_for(void); The second version will break out of a while loop depending on whether a pair of...

    Change the factorial method to return a BigInteger. You can leave the parameter value alone (ie, the parameter will remain an integer). You'll need to modify the method to use BigInteger objects and instance methods. Hint: remember that you can easily form Strings from numerical values by concatenating the numerical value with the empty String "". For Example: String s = 5 + ""; •What happens when you rerun your loop in main? Do you get the correct answers? import...

    Project Objectives: To develop ability to write void and value returning methods and to call them -- Introduction: Methods are commonly used to break a problem down into small manageable pieces. A large task can be broken down into smaller tasks (methods) that contain the details of how to complete that small task. The larger problem is then solved by implementing the smaller tasks (calling the methods) in the correct order. This also allows for efficiencies, since the method can...
