The question will come up concerning the precedence of operators. Which operators are evaluated first and which last? There are many rules about this topic, which your compiler will define completely, but I would suggest that you don’t worry about it at this point. Instead, use lots of parentheses to group variables, constants, and operators in a way meaningful to you. Parentheses always have the highest priority and will remove any question of which operations will be done first in any particular statements.
Goingon to the next example in group three,wefind three simple variables used in the conditional part of the compare. Since all three are non-zero, all three are "true", and therefore the "AND" of the three variables are true, leading to the result being "true", and "z" being assigned the value of 11. Note the since the variables, "r", "s", and "t" are "float" type variables, they could not be used this way, but they could each be compared to zero and the same type of expression could be used.
Continuing on to the fourth example of the third group we find three assignment statements in the compare part of the "if" statement. If you understood the above discussion, you should have no difficulty understanding that the three variables are assigned their respective new values, and the result of all three are non-zero, leading to a resulting value of "TRUE".
