Answer to Question #284604 in C++ for GET

Question

10. If the variable divisor is not zero, divide the variable dividend by divisor, and

store the result in quotient. If divisor is zero, assign it to the quotient. Then print

all the variables. Assume the dividend and divisor are integer and quotient is a

double.

11. write a program that create the following number patern.

1 2 3 4 5 6 7 8 9

1 2 3 4 5 6 7 8

1 2 3 4 5 6 7

1 2 3 4 5 6

1 2 3 4 5

1 2 3 4

1 2 3 1 2

12. Write a program that accepts student mark out of 100, and return the

corresponding letter grade based on the following condition:

if mark is greater than or equal to 90 A

if mark is greater than or equal to 80 and less than 90 B

if mark is greater than or equal to60 and less than 80 C

if mark is greater than or equal to 40 and less than 60 D

if mark is less than 40 F

for other cases NG

N.B write the program using both switch and else-if
