The binary representation of a string is entirely dependent on its encoding. If you want to use the simple ASCII case (one byte per character), then all you need to do is look up the hex code for the character you care about, 0x41 for 'A' for instance. From this point, converting it to a binary sequence is trivial.

2011年7月26日 · Assuming that by "binary code" you mean just plain old data (sequences of bits, or bytes), and that by "letters" you mean characters, the answer is in two steps. But first, some background. A character is just a named symbol, like "LATIN CAPITAL LETTER A" or "GREEK SMALL LETTER PI" or "BLACK CHESS KNIGHT".

The answer depends on what you mean by binary code. Java bytecode is a binary data format that includes loading information and execution instructions for the Java virtual machine. In that sense, Java bytecode is a special kind of binary code. When you use the term "binary code" to mean machine instructions for a real processors architecture ...

2013年7月11日 · Note that on Linux (and on Unix-based systems generally), the b flag is 'optional' — there is no distinction made between a binary file and a text file on such systems. The difference matters intensely on Windows, though. If your code has pretensions to portability, add the b when you're going to treat the file as a binary file. –

2011年7月27日 · For example to request the OS to open a window on the display, open a network connection, allocate memory, and so forth. All that actually is happening is that the CPU just jumps to executing code at a different location (i.e. it jumps from running the code in the executable, to running some piece of code in the OS, and then jumps back).

2011年2月26日 · Note that this output is ready to be assembled back into an object file, so you can tweak the code at the asm source level, rather than with a hex-editor on the machine code. (So you aren't limited to keeping things the same size.) With no changes, the result should be near-identical. It might not be, though, since disassembly of stuff like

The Python package Binary Fractions has a full implementation of binaries as well as binary fractions. You can do your operation as follows: from binary_fractions import Binary b = Binary(6) # Creates a binary fraction string b.lfill(8) # Fills to length 8 This package has many other methods for manipulating binary strings with full precision.

2012年5月30日 · Since you want to "compile by hand", this basically means translating assembler mnemonics above to their opcodes, and then wrapping the result in correct binary format (ELF in the example above) UPDATE: As this answer shows by @adam-rosenfield, the ELF binary for "Hello, world!" can be handcrafted down to 116 bytes.

2013年6月15日 · In real code examples, you can meet O(log(n)) in binary search, balanced binary search trees, many resursive algoritmhs, priority queues. Share Improve this answer

2024年2月12日 · With pure machine code, you can use any language that has an ability to write files. even visual basic.net can write 8,16,32,64 bit while interchanging between the int types while it writes. You can even set up to have vb write out machine code in a loop as needed for something like setpixel, where x,y changes and you have your argb colors.
