Way back in homework P01, you wrote the classic “Hello, World!” program in Java. Now that we’re learning a

bit about C++, let’s retread that hallowed ground!

Full Credit

For this full credit assignment, we will repeat both the P01 full credit and bonus assignments – in C++!

If you haven’t already, set up your C++ development environment using guidance from Lecture 00 (slides
14-15). Then in cse1325/P08/full_credit, create and run the C++ “Hello, World!” program in file hello.cpp
using std::cout, replacing “World” with your name. Take a screenshot of your program running, and name
it hello_me.png.

Then create and run a C++ program from file hello_all.cpp that asks the user for their name, then prints “Hello,
[name]”, where [name] is the name they enter. Test this at least 3 times – with a single-word name, with a
mult-word name separated by spaces, and by a name with different (potentially weird) characters. Take a
screenshot of your program running all of these tests, and name it hello_all.png. As long as your program
prints something after “Hello, “, you get full credit regardless of the outcome of these 3 or more tests.

Add hello_me.cpp, hello_me.png, hello_all.cpp, and hello_all.png to git, commit, and push to GitHub. Bonus

write a C++ program in file reverse.cpp that prints each of its parameters with the
characters reversed. That is, ./a.out hello world would print olleh dlrow (on one line or separate
lines, your choice).

No screenshots are required.

Hint: std::string has a constructor that will accept a char*.

Hint: std::string is a collection of chars.

Hint: The std::reverse function (from <algorithm>) will reverse a collection in place. To reverse any collection
foo, write std::reverse(foo.begin(), foo.end()); (this rather odd syntax was chosen so that a
subset of a collection could be easily reversed).

Add, commit, and push all files.

Extreme Bonus

write a program in file sorted.cpp that reads all newline-terminated lines of
text from the console until end of file. Then, print all of the lines of text back out sorted in alphabetic order.

No screenshots are required.

Hint: The equivalent of Java’s ArrayList<String> would be the std::vector<std::string> (from

<vector>). Rather than add, use the push_back method, e.g.,

std::vector<std::string> v; v.push_back(“Hi!”);

Hint: std::vector is a collection of objects of the type specified in the angle brackets < >.

Hint: The std::sort function (from <algorithm>) will sort a collection in place. To sort any collection foo, write

std::sort(foo.begin(), foo.end()); (this rather odd syntax was chosen so that a subset of a
collection could be easily sorted).

Hint: You can redirect a text file foo.txt into your program with bash’s < operator, e.g., ./a.out < foo.txt If
you prefer to type the lines of text yourself, you can type an end of file signal using Control-d (for Linux or Mac)
or Control-z (for Windows).
