Dev C++ Programs

Assembly speed = C as C is compiled into assembly code. With handwritten assembly, you might be able to make the routine more efficient than the C compiler does. On most modern systems though, the results aren't noticeable. The difference is that C is much faster development time while assembly is much better for custom processors. You can call C code from assembly almost as easily, by making the C code extern 'C', using 'extern someName' in assembly, and then call the function normally. Mixed Assembly and C at the Command Line The most portable way to include some assembly functions in your code is to compile the assembly in a separate file, then link it with the C. Dev-C seems to use GCC. You can try this option: gcc -S -masm=intel as answered in this question: How do you use gcc to generate assembly code in Intel syntax? I do not know how to set command line options on Dev-C but guides can be easily found.

Dev C++ Games

Dev-C++ is a free IDE for Windows that uses either MinGW or TDM-GCC as underlying compiler.
Originally released by Bloodshed Software, but abandoned in 2006, it has recently been forked by Orwell, including a choice of more recent compilers. It can be downloaded from:
http://orwelldevcpp.blogspot.com

Installation

Run the downloaded executable file, and follow its instructions. The default options are fine.

Support for C++11

By default, support for the most recent version of C++ is not enabled. It shall be explicitly enabled by going to:
Tools -> Compiler Options
Here, select the 'Settings' tab, and within it, the 'Code Generation' tab. There, in 'Language standard (-std)' select 'ISO C++ 11':
Ok that. You are now ready to compile C++11!

Compiling console applications

To compile and run simple console applications such as those used as examples in these tutorials it is enough with opening the file with Dev-C++ and hit F11.
As an example, try:
File -> New -> Source File (or Ctrl+N)
There, write the following:
Then:
File -> Save As... (or Ctrl+Alt+S)
And save it with some file name with a .cpp extension, such as example.cpp.
Now, hitting F11 should compile and run the program.
If you get an error on the type of x, the compiler does not understand the new meaning given to auto since C++11. Please, make sure you downloaded the latest version as linked above, and that you enabled the compiler options to compile C++11 as described above.
