[Shikaan] has an introductory article aimed to get you started at the “hello world” level of x86-64 assembly language. The second part is already up, too, and covers control structures.

Today, C/C++ is widely used instead. Like assembly language, C/C++ can manipulate the bits at the machine level, but it is also portable to different computer platforms. There are C/C++ compilers ...

On a modern processor it is very hard (and inefficient) to write machine code by hand, typing in the raw numbers. So there is a slightly higher level language called assembly language which is a ...

A line of code in assembly language is typically converted into one machine instruction. In a high-level language such as C++ or Java, one line of code generates a series of assembly language ...
