3. What does the following statement print if i has the value 17? What does it print if i has the value-17?

printf("%d ", i >= 0 ? i : -i);

3.

4. The following if statement is unnecessarily complicated. Simplify it as much as possible. (Hint: The entire statement can be replaced by a single assignment.)

if (age >= 13)

if (age <= 19)

teenager = true,- else

teenager = false;

else if (age < 13)

teenager = false;

If so, what does it do when n is equal to 5?

Write your answer here:

4.

5. Are the following if statements equivalent? If not, why not?

(1)

if (score >= 90)

printf("A");

else if (score >= 80)

printf("B");

else if (score >= 70)

printf("C");

else if (score >= 60)

printf("D");

else

printf("F");

(2)

if (score < 60)

printf("F");

else if (score < 70)

printf ("D" );

else if (score < 80)

printf("C");

else if (score < 90)

printf("B");

else

printf("A");

Programming Projects

5.2

1. Write a program that asks the user for a 24-hour time, then displays the time in 12-hour form:

Enter a 24-hour time: 21:11

Equivalent 12-hour time: 9:11 PM

Be careful not to display 12:00 as 0:00.

1. Write your program here:

#include

int main(){

return 0;

}

2. Heres a simplified version of the Beaufort scale, which is used to estimate wind force:

Speed (knots)	Description
Less than 1	Calm
1~3	Light air
4~27	Breeze
28~47	Gale
48~63	Storm
Above 63	Hurricane

Write a program that asks the user to enter a wind speed (in knots), then displays the corresponding description.

2. Write your program here:

#include

int main(){

return 0;

}

3. Write a program that finds the largest and smallest of four integers entered by the user:

Enter four integers: 21 43 10 35

Largest: 43

Smallest: 10

Use as few if statements as possible. Hint: Four if statements are sufficient.

3. Write your program here:

#include

int main(){

return 0;

}
