This is the base page of the section of Software,compilers.
The content you are looking for can be found via the navigation to your left ←. some of these folder index pages have content, but most like this one don't.
There are several free compilers out there (see navigation on left) that you can choose from, most of which allow for Open SourceSoftware develoopment and use by students.
One that is not is Microsoft Visual Studio Express, it is not licensed for distribution of source code with executable as a student would be required to do (sorry!). But there are wonderful alternatives that can deal with 64-bit numbers and have the STL and TR1, such as MinGW-w64.
always read the license agreement carefully before using a compiler.
