Eclipse will only compile one file [message #1837926]

Ok, so I am new to coding and to using Eclipse. I have successfully built my first Hello World program. The problem is when I create a new program the compiler just compiles and runs the previous one. Why is it doing this? I admit that I don't yet understand how this IDE works. So if you take a look at the screen shot you will see the output of the hello world program and not the output of what I just tried to compile.

Hi,

I think that you use the "run" button on the toolbar? That is set to run the executable from your "Project1". And if that is not the project that contains the main from your screen dump it runs the wrong program.

From you screen dump I deduce that you are learning C++. What I say to my students is that they should create a new project for each assignment/exercise and that they should always close all other projects except the one they are working on, until they are familiar enough with Eclipse. It prevents them from editing the wrong source files, compiling the wrong project and running the wrong executable.
