Binary numbers in Python
You can convert between a string representation of the binary using bin() and int()

How to reverse an std::string? [duplicate]
Im trying to figure out how to reverse the string temp when I have the string read in binary numbers
How do you express binary literals in Python?
For reference—future Python possibilities:Starting with Python 2.6 you can express binary literals using the prefix 0b or 0B: You can also use the new bin function to get the binary representation of a number: Development version of the documentation: What’s New in Python 2.6
C++ – Decimal to binary converting
std::bitset has a .to_string() method that returns a std::string holding a text representation in binary, with leading-zero padding. Choose the width of the bitset as needed for your data, e.g. std::bitset<32> to get 32-character strings from 32-bit integers. EDIT: Please do not edit my answer for Octal and Hexadecimal. The OP specifically asked for Decimal To Binary.
Why unsigned int 0xFFFFFFFF is equal to int -1?
C and C++ can run on many different architectures, and machine types. Consequently, they can have different representations of numbers: Two’s complement, and Ones’ complement being the most common. In general you should not rely on a particular representation in your program. For unsigned integer types (size_t being one of those), the C standard (and the … Read more
bad operand types for binary operator “&” java
== has higher precedence than &. You might want to wrap your operations in () to specify how you want your operands to bind to the operators. Similarly for all parts of the if condition.
Bash: No such file or directory?
I bet you miss dynamic linker. Just do a You should get an output like this: There are high chances that you system lacks the interpreter (/lib64/ld-linux-x86-64.so.2 in the example). In this case bash would yell No such file or directory, just like when the binary itself is missing. You can try to use a different linker. Sometime you can … Read more
Why prefer two’s complement over sign-and-magnitude for signed numbers?
It’s done so that addition doesn’t need to have any special logic for dealing with negative numbers. Check out the article on Wikipedia. Say you have two numbers, 2 and -1. In your “intuitive” way of representing numbers, they would be 0010 and 1001, respectively (I’m sticking to 4 bits for size). In the two’s … Read more
What is “2’s Complement”?
Two’s complement is a clever way of storing integers so that common math problems are very simple to implement. To understand, you have to think of the numbers in binary. It basically says, for zero, use all 0’s. for positive integers, start counting up, with a maximum of 2(number of bits – 1)-1. for negative … Read more
