2019年1月5日 · This program converts a decimal number to a binary number. This is one of my first C programs and I am wondering if I have used the elements of this language properly. Suggestions for improvement are

2021年11月21日 · You are formatting a number into a binary representation. Normally this is done to produce a string, not an array of integers. The native number is an abstraction, not a text string in any base. Though, you can be aware that the internal representation in the CPU is in fact binary: you are doing this with the use of >> instead of /2, though you ...

2023年6月10日 · \$\begingroup\$ 100% agreed the XOR bithack is not a good idea in this code, though! If you want to write something easily readable that's more likely to compile to efficient asm given C's lack of a rotate builtin or capturing carry-out from a left shift, looping backwards like you're doing and taking the low bit is good.

2019年1月6日 · The point of a to_binary function is pretty much always because you for some reason want a textual representation in binary. As a quick side note, Rust already has the ability to convert values to binary: format!("{:b}", value); Your to_binary function would be a bit simpler if build a Vec or Vec and then converted that instead of building a ...

It will shave off numerous instructions.

2017年9月19日 · binary_to_decimal takes in a string of binary digits and returns a string of the very same number, but with decimal digits. binary_to_hexadecimal works similar; it takes a string and returns a string of hexadecimal digits. I leave actually writing these functions to you.

2020年10月16日 · The name bin_digits is actively misleading: it does not contain the binary digits. It contains the number of binary digits. Oh, and also, the term "binary digit" is usually shortened to "bit". So, it should be called bit_length or number_of_bits. Not naming. As I wrote above, naming is hard, and names are important.

2019年1月22日 · For example, number 9 has binary representation 1001 and contains a binary gap of length 2. The number 529 has binary representation 1000010001 and contains two binary gaps: one of length 4 and one of length 3. The number 20 has binary representation 10100 and contains one binary gap of length 1. The number 15 has binary representation 1111 and ...

2013年12月27日 · \$\begingroup\$ Also the loop will run in time proportional to the number of ones sounds imprecise as well - the number of iterations of the loop doesn't depend on the number of ones, it merely depends on the position of the most significant one. \$\endgroup\$ –

2016年4月22日 · I've made a very simple program that takes integer number arguments either with plus/minus sign or without them, and print the number in binary format. binary.c #include <stdio.h> void
