No, you won't. The first command installs gcc and its dependencies. If you don't have a C compiler installed on that system, just downloading this library won't cut it. You would need to download and install a C compiler too.Originally Posted by VENOM
However, if you have a C compiler installed, then once you have cs50-library-c-3.1.zip, the third and subsequent steps will be the same (assuming the C compiler is gcc) whether you use wget to download the zip archive or downloaded it from your thumb drive (i.e., the second step).
