Question

3. (a) Create a table of 0 to 15 decimal equivalents in Binary and Hex. (b) Add 4AB (hex) plus A33 (Hex). Show the answer in Hex. Demonstrate your understanding of the if else construct by writing code that asks a person their number grade and prints out an appropriate letter grade A,B,C,D, or F. (e.g. enter: "87" code prints out: "B", etc.) 4. Write a C++ code that will ask a person their favorite color, will then tell them what that color backwards is. (example: Orange 5 egnarO) Consider a function called: "MyFunction", making up your own variable names for any parameters. Show what the function prototype for that function would look like if: (a) it had no parameters passed to it, and no values returned. (b) three integer parameters passed to it, and no values returned. (c) a double passed to it, and an integer returned. 6. 7. Describe/illustrate/explainsomething that you learned this semester in this course that was not asked about in any other question on this exam Note: You can not just mention the name of the topic/construct-you have to show that you understand it.

Answer 1

3.

a)

Decimal Number	4-bit Binary Number	Hexadecimal Number
0	0000	0
1	0001	1
2	0010	2
3	0011	3
4	0100	4
5	0101	5
6	0110	6
7	0111	7
8	1000	8
9	1001	9
10	1010	A
11	1011	B
12	1100	C
13	1101	D
14	1110	E
15	1111	F

b)

4AB + A33 = EDE₁₆

4.

grade = input("Enter your number grade: ")

if (grade >= 90 and grade <= 100) {

print("A");

} else

if (grade >= 80 and grade < 90) {

print("B");

} else

if (grade >= 70 and grade < 80) {

print("C");

} else

if (grade >= 60 and grade < 70) {

print("D");

} else {

print("F");

}
