Compare Boolean Variables in one statement as long as array C++

  • A+

Lets say I have an boolean array with 5 bool variables all being true

bool boo[10]; for(int i = 0; i < 5; i++){     boo[i] = true; } 

I want them all compared into one NAND logic gate at once because my problem is if I always compare two variables and compare the merged boolean to the i+1 boolean variable. This gives a wrong result.

    bool NANDGate(bool array[]){     bool at;     for(int i = 1; i < 5; i++){         if(i == 1){             at = !(array[i-1] && array[i]);         }else{             at = !(at && array[i]);         }     }     return at; } // result here is true even though it should be false 

What I want is a right result when I put every variable from boo into a NAND gate so something maybe that looks like this:

bool func(bool array[]){ // some loop result = !(array[0] && array[1] && array[2] && array[3] && array[4]); return result; } // result here would be false 

actually it doesn't have to look like that just maybe a solution that has a right result like the above would have.

EDIT: So many great solutions I thank you all


The following should do it:

bool NANDGate(bool array[]) {     for(int i = 0; i < 5; i++)     {         if (!array [i])             return true;     }     return false; }
