Consider two linked lists list1 with Integer values [1,2,3] and list2 with Integer values [4,5,6,7,8,9]

Suppose the merge method is called on list1 with list2 as parameter.

How many time will the following loop while((ptrThis != null) && (ptrParam != null)) iterate? Blank 1. Fill in the blank, read surrounding text.

After 3 iterations what will the value of ptrThis be? Blank 2. Fill in the blank, read surrounding text.

What will the value of ptrParam be? Blank 3. Fill in the blank, read surrounding text.

Do the pointer in both lists reach null at the same time? Yes/No Blank 4. Fill in the blank, read surrounding text.

What follows is a fill in the blank question with 9 blanks.

The curly bracket used in java to enclose units of code can not be used in a fill in questions. For this

questions the curly brackets will be substituted with comments. Interpret the open and close comments as curly brackets.

Given the following method with an array values [7,2,5,8,3,9]

public static int sumValues(int index)

//open method

if(index>=values.length)

return 0;

else

return values[index] + sumValues(index +1);

//close method

Is sumValues(4) a valid call? Yes/No Blank 15. Fill in the blank, read surrounding text.

If so what is returned from the method? returned value or No Blank 16. Fill in the blank, read surrounding text.

Is sumValues(1) a valid call? Yes/No Blank 17. Fill in the blank, read surrounding text.

If so what is returned from the method? returned value or No Blank 18. Fill in the blank, read surrounding text.

Albert Einstein teaches a business class at Podunk University. To evaluate the students in this class, she has given four tests. It is now the end of the semester and Alberta would like to have a program that inputs each student’s test scores and outputs the average score for each student and the overall class average. (Hint: The outer loop should allow for Ms. Einstein to input all the students, one by one, and the inner loop should accept the four exam scores and compute the average for each student

Write a file copy program that prompts the user to enter the name of a text file to act as the source file and the name of an output file. The program should use the toupper() function from ctype.h to convert all text to uppercase as it’s written to the output file. Use standard I/O and the text mode
