Random Binary number

[SurviBee]

I need to generate a random binary number (or decimal and convert it), and store that number in an array, needless to say im lost and would appreciate any help. Thx

All numbers are stored in binary. Do you mean generate a random number and then save the binary conversion as a string?

exactly, just need it to be 8 bits long, I've looked around i just cant find anything that doesnt just output it to the screen

The bitset class lets you work with bits, and you can easily print them too.

#include <bitset>
#include <cstdlib>
#include <iostream>

using namespace std;

int main() {
  for ( int i = 0; i < 10; ++i ) {
    cout<< bitset<8>( unsigned char( rand() ) ) <<"\n";
  }

  return 0;
}

There's also a to_string() method that turns the bitset into a string that you can store. But if this is homework I don't know if your teacher will let it slide.
