Binary format & literals in C++
cout « std::bitset<32>( 0b1000’0000’0000’0000 ) - Binary solo
C++14 binary literals and digit separator
auto binary=0b10001000 ; //binary digit
auto hex=0x12ab; ///hexadecimal number
auto octal=0127 ; //octal number
auto B16=0b1000’0000’0000’0000 , //easier to guess the number Printing numbers in binary format in C++
In C++20 you’ll be able to use std::format to do this
std::cout << std::format("{:b}", a);otherwise
The easiest way is probably to create an std::bitset representing the value, then stream that to cout.
#include <bitset>
int v = 0x12345678;
std::cout << std::bitset<32>(v);see also
