compile and run C++ program

[nickyeng]

In java environment, i compile and run program using "javac" and "java" respectively.

So, now is C++.

Compile c++ program (hello.cpp) , we type:

$ g++ testing.cpp

and to run that program, we type:

$ ./testing

as same in the below image:

OR this way.
---------------------------------------
Nick@ACER-Nick ~
$ g++ testing.cpp -o testing
$ testing
Hello C++ World!
$
---------------------------------------

Can you see any different from the image and the other way of compile-run program ?

No because they are the same method.

the "./" just means "in the current directory", since the current directory is assume by default it can be left off so "./testing" and "testing" are the same file accessed in the same manor.

i know about "/testing" and "testing"

but why the following "run program" fails?

that's why i explicitly mention the 2 ways of compile-run program methods.

Hi,

The second method will work if you do the follwoing things.

Append the . to the PATH environment variable.
So it will work as you are expecting..

where to change the PATH environment variable? i'm using cygwin.

Do an 'ls -a' which will show you all the hidden files - my guess is it is in your .bash_profile or your .bashrc

Insert the code

  for(;;)
    ;
 

just before the end of main so that the program does not stop running.

No you have asked that the console doesn't return to the command prompt once the program has finished running.

This is not possible the only way to prevent a return to the command prompt is not to end the program, which is what the code I have posted will do.
