1) these are operators that add and subtract one from their operands.

a) plus and minus
b) ++ and --
c) binary and unary
d) conditional and relational
e) none of these

2) what is the output of the following code segment?
n = 1; while (n < = 5) cout < < n < < ' '; n++;

a) 1 2 3 4 5
b) 1 1 and on forever
c) 2 3 4 5 6
d) 1 2 3 4
e) 2 3 4 5

1) B (++ and --)

2) A (1 2 3 4 5)

Explanation:

In the first question, the operators ++ and -- are used in almost all programming languages for adding  and subtracting  1 respectively from an operand.

In the second question using a while statement the numbers 1-5 is printed out because the variable n=1 is increased by 1 after each iteration.

why wouldnt you just google the words bud? not that hard to
