Here is an eplanation of how to do it;

you can easily increment or add one to a variable with the ++ operator.

i++;

is the equivalent of

i = i + 1;

Note
The entire line becomes i++; , eliminating the need for the equal sign.

Knowing this, how would you simplify myVar = myVar +1 to mean the exact same thing with the knowledge above that ++ adds one to the variable?
