c++ - 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 binary, because in my code, x can be anywhere between 0 and 2^32-1, since

cout<<(int)x;

doesn't do the trick, how would I do it?

A bit late, but, as Katy shows in her blog, this might be an elegant solution:

#include <bitset>
#include <iostream>

int main(){
  int x=5;
  std::cout<<std::bitset<32>(x)<<std::endl;
}
