I just downloaded Visual Studio 2013. When I compile C, it doesn\'t show me my output. The output screen will show up for a brief second and then disappears.
Another option in addition to what's already been mentioned is to go into the properties for the project and change the Subsystem in the System section in the Linker options to Console (/SUBSYSTEM:CONSOLE). Then the console window will remain when you run the program using ctrl+f5 (Debug/Start without debugging).
MSDN reference for the subsystem option.
