1. isSalary employee, isHourly employee, getSalary employee and getDeparment employee: The functions isSalary, isHourly , getSalary and getDepartment access specific fields of the employee tuple and return either a boolean (in the case of the is functions) or a value (in the case of the get functions).

Asequential circuit contains a register of four flip-flops. initially a binary number n (0000 ≤ n ≤ 1100) is stored in the flip-flops. after a single clock pulse is applied to the circuit, the register should contain n + 0011. in other words, the function of the sequential circuit is to add 3 to the contents of a 4-bit register. design and implement this circuit using j-k flip-flops.

Avariable of the data type arrays is storing 10 quantities. what is true about these quantities? a. the quantities all have different characteristics. b. the quantities all have the same characteristics. c. five quantities have the same and five have different characteristics. d. it is necessary for all quantities to be integers. e. it is necessary for all quantities to be characters.

Experimental data that is expressed using numbers is said to be
