The Python bin() function is used to convert an integer number to its binary representation. It takes an integer as an argument and returns a string that represents the binary equivalent of the input integer. The returned string starts with the prefix ‘0b’ to indicate that it is a binary number. For example, bin(10) will return ‘0b1010’, which is the binary representation of the decimal number 10. The bin() function is useful in situations where binary operations need to be performed on integer values, such as bitwise operations or binary arithmetic..

Python ‘bin’ in C++ With Example Code

Python’s `bin()` function is a useful tool for converting integers to binary strings. However, what if you need to use this functionality in a C++ program? Fortunately, it’s not too difficult to implement your own version of `bin()` in C++.

First, let’s take a look at how `bin()` works in Python. Given an integer `x`, `bin(x)` returns a string representation of `x` in binary format. For example, `bin(5)` returns the string `”0b101″`. The `”0b”` prefix indicates that the string represents a binary number.

To implement this functionality in C++, we can use a bitset. A bitset is a fixed-size sequence of bits that can be manipulated as a single entity. We can create a bitset with a size equal to the number of bits needed to represent the integer in binary format. For example, if we want to represent the integer `5` in binary format, we need 3 bits (`101`), so we create a bitset with a size of 3.

Once we have the bitset, we can set each bit to the appropriate value by iterating over the bits of the integer and setting the corresponding bit in the bitset. Finally, we can convert the bitset to a string representation by iterating over the bits and appending either `”0″` or `”1″` to the string.

Here’s an example implementation of `bin()` in C++:


std::string bin(int x) {
std::bitset<32> bits(x);
std::string result;
bool leading_zeros = true;
for (int i = 31; i >= 0; i–) {
if (bits[i]) {
leading_zeros = false;
if (!leading_zeros) {
result += bits[i] ? “1” : “0”;
return result.empty() ? “0” : “0b” + result;

In this implementation, we create a bitset with a size of 32 (the maximum size of an integer in C++). We then iterate over the bits of the integer in reverse order, setting the corresponding bit in the bitset and appending `”0″` or `”1″` to the result string as appropriate. We also keep track of whether we have encountered any leading zeros, so that we can omit them from the result string.

With this implementation of `bin()` in C++, you can easily convert integers to binary strings just like you would in Python.

Equivalent of Python bin in C++

In conclusion, the equivalent function of Python’s bin() in C++ is the bitset class. Both functions serve the purpose of converting decimal numbers to binary format. However, the bitset class in C++ provides more flexibility and control over the binary representation of the number. It allows the programmer to set the size of the binary representation and also provides various operations that can be performed on the binary representation. Overall, the bitset class is a powerful tool for working with binary numbers in C++ and can be used in a variety of applications.
