LAB EXERCISE 4 – SELECTION AND MATH.H

Exercise 1:

Write a program which asks from user for two round numbers and determine which one is larger. The output should similar to:

Exercise 2:

Write a program which asks the user to enter an exam mark, and then displays whether or not the mark is valid. Hence it will display the grade for that mark.

Example of the program output display (user input is in bold):

Enter your mark: 150The exam mark must be between 0 and 100 inclusive.

Enter your mark: 45Your grade is C.

F

Moving Distance

Exercise 3:

Write a program to calculate area of a circle(Note: area= PI*rad2 and Use pow() from the standard library <math.h>). Example of the program output display (user input is in bold):

Exercise 4:

Write a program which asks the user to enter force, angle and meters of moving distance.Note: W=F*S (W=(F cos θ) x s) sample calculation 25 cos 60 ̊̊ x 8meters. Example of the program output display:
