how to output an int in binary?

Question

int x = 5;
cout<<(char)x;

the code above outputs an int x in raw binary, but only 1 byte. what I need it to do is output the x as 4-bytes in

Answer 1

You can use the std::ostream::write() member function:

std::cout.write(reinterpret_cast(&x), sizeof x);

Note that you would usually want to do this with a stream that has been opened in binary mode.
