- 1. Identify the following parameters to complete the specification above. Input parameters? Output parameters? Constant parameters? 2. Attach the input and output of a successful execution of your program below (Hint:Use the snipping tool to take screenshots):arrow_forwardComplete the following questions about different types of variables:i. Check the last digit of your id number(123456789). If it is even or 0, fill the gap in (A)with the word global (i.e., static global), otherwise, fill it with local (i.e., static local).Then, complete Table I. ii. In a multi-source program, there is a fileA.c that contains variables and functions,and a fileB.c that contains the main function, as well as usage of some of theresources found in fileA.c. Explain:a) fileA.c has a global variable called my_variable, that should only beaccessed within the file. I.e., no other files should be able to access thatvariable.How should my_variable be declared inside of the file, in order to guaranteethis functionality? b) fileA.c also has a global variable called my_shared_variable, which canand should be accessible from other files, including fileB.c.How should my_shared_variable be declared in order to allow thisfunctionality?Note for item ii): You also need to state in a…arrow_forwardWhich of the following statements about debugging is NOT correct?: A -In some ways debugging is like detective work. You are confronted with clues and you have to infer the processes and events that led to the results you see. B -Once you have an idea about what is going wrong, you must delete your program and completely rewrite all of the code all over again. C -For some people, programming and debugging are the same thing. That is, programming is the process of gradually debugging a program until it does what you want. D -Although it can be frustrating, debugging is one of the most intellectually rich, challenging, and interesting parts of programming.arrow_forward
