It is recommended that you use either
emacs/xemacs
or vi/vim
to edit those files.
nano
would be OK too if you are not yet comfortable with
vi/emacs
. You can also edit the files using your favorite editor
(Eclipse
, Nodepad++
, sublime text
, etc.)
from your home/laptop OS and upload them to your CSE account.
There's no way I know how you did it.
report.cpp
(please do not cut-and-paste, though I wouldn't know if you cut-and-pasted or
typed, I'd recommend typing to get a sense of the editor, the C++ syntax, and
indentation, ...)
// report.cpp #include <iostream> using namespace std; int main() { string my_name = "David Blaine"; // edit this string my_text_editor = "emacs"; // edit this string my_home_os = "Windows"; // edit this bool i_worked = true; // set to false if you didn't do work cout << "My name is " << my_name << endl; if (i_worked) { cout << "I was able to install and test g++ and " << "the text editor " << my_text_editor << '\n' << "in my home computer/laptop, which runs " << my_home_os << endl; } else { cout << "I wasn't able to install and test g++ and/or a text " << "editor because ... " // give a lame reason here << endl; } return 0; }You must modify the program so that it reports things about you. Now, to compile the above program, you can do
g++ report.cpp
and run it with a.out
.
However, I'd like you to try an extremely
simple Makefile
too.
Makefile
in the same directory whose content consists of the following lines:
all: g++ report.cpp clean: rm -f a.outFor the
Makefile
to work, it is crucial that there is exactly
one tab before g++
on the second line, and there is exactly one tab before rm
on the 5th line. (The 3rd line is empty.)
Then, when you type make
at the command line you'll get the same
effect as if you were typing g++ report.cpp
. You can run the program by typing a.out
or ./a.out
if your $PATH
variable was not set correctly.
README
with the following content:
Name: David Blaine // please replace with YOUR name Person number: 1234-5678 // please replace with YOUR person numer
a.out
file that was compiled and run. We do not want you to submit executables, only the source files. Hence, please type
make cleanat the prompt before submitting. The effect is to remove the
a.out
file, if any, that was created.
Finally, to submit, create a tar ball of the directory as follows.
cd .. tar -cvf A0.tar A0/* submit_cse250 A0.tarNote that the last line only works if you logged in to your CSE account and the tar file is there. All previous things can be done at home, as long as you remember to upload the final tar file to your CSE account and run the submit script from there.
