What if you declared the bool status at the begining and if the required task is performed, the status is changed

0

Since Addition is a boolean value, you could also simply code:

if (Addition) { //do whatever }

That is of course unless you are attempting to make the boolean value true...which would defeat the purpose of checking it in the conditional statement in the first place...

Note: You have similar syntax elsewhere in your code, i.e. lines: 47, 76, 105, 134, 163, 192, 221, 250, 279, 378, 385, 392, 399...

You need to change e.g. if(Addition = true) to if(Addition == true)

ah yes. i always get confused with logical and bitwise operations
