WebApr 13, 2014 · bool[] sensorstat This should change the value of the boolean. But is doesn't, it just initialize a vector of 4 booleans which stay constant. changing the for loop into the following : for(int i=0 ; i <4;i++) { if (buttonState.sensorstat[i]) {buttonState.sensorstat[i] = false; } else { buttonState.sensorstat[i] = true;} } WebThere are (at least) two ways: Make arrays of HIGH and LOW values, matching the digitPins [] and segPins [] arrays one-for-one, respectively. Or for easier maintenance, declare a data structure ( struct) of a pin # and a value; make an array of those. It's a bit more complex but also more useful. So, for example:

Casting a pointer for different types will only work if both types have the same size. But even then you should know what you do (know how to interpret and use the casted data). You try to print out a single character (use the * dereference operator). dr hayward cape girardeau
