a. What part of a C implementation changes the text of a C program just before it is
compiled? Name two directives that give instructions about these changes.
b. Write this equation as a C statement using functions exp, log, and pow:
y =
(enlnb)?
c. Write assignment statements for the following:
1. Assign a value of 1 to between if n is in the range -k through +k, inclusive;
otherwise assign a value of 0.
2. Assign a value of 1 to uppercase if ch is an uppercase letter; otherwise,
assign a value of 0.
3. Assign a value of 1 to divisor if m is a divisor of n; otherwise, assign a
value of 0.
d. You are given a queue with 4 functions:
engue (gux), v<-dequeue (q), new (q), and b<-isNotEmpty(q),
empty
where q is a queue, v is the value put on the queue, new creates a nev
queue, isNotEmpty tests the queue, and b is a Boolean. What will this
pseudocode program print?
new (s);
engueue la, "a");
engueue la, "b");
enqueue (q, "c");
enqueue (q, "d");
engueue (q, "e");
while (isNotEmpty(q)) do {print(dequeue (q) ); }
print ("\n");
![e. What would be the best variable type to use to represent the following items:
a.
area of a circle in square inches,
b. the number of cars passing through an intersection in an hour, and
c. the first letter of your family/last name?
f. What will be printed by this switch statement if the value of color is 'R'?
switch (color) {
case 'R’:
printf("red\n");
'B' :
printf("blue\n");
case
case
'Y' :
printf("yellow\n");
}
g. During the execution of the following program segment, how many lines of
asterisks are displayed?
for (=0; i<10; ++i)
for (j=0; j<5; ++j)
printf("********** \n");
h. When will the error in the following C statements be detected?
int x18], i
for (i=0; i<=8; ++i)](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F8cb58778-70ba-4f7e-90ce-7267bd79a013%2Fa3633c7a-40b5-44e6-bb4f-f369e91b474d%2Fzd5pdvc_processed.png&w=3840&q=75)
