Unix/Linux Assignment 9
Please Help!
1.Create a directory ~/UnixCourse/compileAsst
2.Copy the files from ~cs252/Assignments/guess/ into your newly created directory.
3.Compile the code, capturing the error messages by any of the techniques covered in this modules lesson.
4.
Open a separate ssh session in a second window. In there, give the command:
~cs252/bin/compileAsst
This will ask you some questions about the errors that you observed.
Eventually, it will instruct you to fix the errors and to recompile the code.
5.In your first window, use an editor to fix the errors in the code.
Each error can be fixed by a change of no more than 2 characters on a a single line. If you find yourself doing anything more complicated, stop!
Then recompile to produce an executable file named program.
1. In your second window, answer any remaining questions.
~I have done almost all the steps correcting the code, what I am stuck on is compiling the files given below and producing a new executable file called "program".~
~cs252/Assignments/guess/ Includes these files:
~cs252/Assignments/guess/guess.cpp

// by asking a series of "Is it bigger than X?" questions.
// Return true if able to guess it. Return false and complain
// if person's responses are inconsistent.
bool doGuesses (int low, int high)
{
if (low >= high)
{
cout << "Hey, no cheating! There is no number that is ";
