Jump to PostAll numbers are stored in binary. Do you mean generate a random number and then save the binary conversion as a string?
Jump to PostThe 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"; …

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.
