Question

what I want to do is check an array of bools to see if 3 or more of them have been set to true. The only way I can think to do this is using a if statement for each possible combination of which there is lots because there are ten bools. Dose anybody have any suggestions on how best to do this.

Answer 1

The much easier way would be to loop through the array:

int numberOfSet = 0;
for( int i = 0; i < sizeOfArray; i++ ) {
     if( array[i] ) {
        numberOfSet++;
        //early cut-off so that you don't loop further without need
        // whether you need it depends on how typical it is to have
        // long arrays that have three or more elements set in the beginning
        if( numberOfSet >= 3 ) {
            break;
        }
     }
}

bool result = numberOfSet >= 3;
