opposite bool compare output, why?

[ozziehazz]

tihs is an extension of the dice game i am making, but i have two string arrays that look like

#include <string>
#include <vector>
#include <iostream>
#include <algorithm>

using namespace std;

int main()
{

string rollone[] = {"one", "two", "two", "three", "three"};
string rolltwo[] = {"two", "three", "three", "one", "two"};


bool equal;
   
     for( int step = 0; step < 5; step++ ) {

equal = rollone[0].compare( rolltwo[step] );
      cout << equal << " ";
     }

   system ("pause");
}

why does this return 1 1 1 0 1 instead of 0 0 0 1 0 i.e. a zero when they are not equal, and a 1 when the two entries are equal?

Return value
0 if the compared characters sequences are equal, otherwise a number different from 0 is returned, with its sign indicating whether the object is considered greater than the comparing string passed as parameter (positive sign), or smaller (negative sign).

i see, i must have missed that part - is there a way without using the ! operator to get it to output 0 0 0 1 0 for the comparison?

What's wrong with NOT?
std::string has operator== overloaded, so you can just do rollone[0]==rolltwo[step].
