- Branching statements (if-then blocks).
- for-loops to execute a chunk of code multiple times.
- Variable assignments.
The computer’s compiler then encodes your program’s statements as low-level instructions that get executed on your computer’s operating system. These low-level instructions replace what you wrote with operations on binary (1 and 0) bits that are held in registers or storage locations accessible by a computer’s central processing unit (CPU):
- Moving bits in and ...
