a.) PLS_INTEGER values require less storage
b.) NUMBER values require less storage
c.) PLS_INTEGER operations use hardware arithmetic, so they are faster than NUMBER operations, which use library arithmetic
d.) For calculations outside the PLS_INTEGER range, use INTEGER, a predefined subtype of the NUMBER data type
e.) A calculation with two PLS_INTEGER values that overflows the PLS_INTEGER range raises an overflow exceptionDeselect Answer

a.) EXIT and CONTINUE can appear anywhere inside a loop, but not outside a loop
b.) EXIT and CONTINUE can appear anywhere inside a loop as well as outside a loop
c.) Both EXIT and CONTINUE can be used with additional WHEN clause to run on specific condition
d.) Only EXIT can be used with additional WHEN clause to run on specific condition

a.) In IF and ELSE statement, ELSE block is always executes irrespective of the IF blocks condition
b.) The IF statement either runs or skips a sequence of one or more statements, depending on a condition
c.) The CASE statement chooses from a sequence of conditions, and runs the corresponding statement
