if statements? What is the role
of if
statements in programs?
pass_fail.c that reads in an integer and
prints out "PASS" if the integer is between 50 and 100 inclusive and
fail if it is between 49 and 0, inclusive. It should print out ERROR
if the number is less than 0, more than 100, or if the user does not
enter a number. For example:
./pass_fail Please enter your mark: 42 FAIL ./pass_fail Please enter your mark: 50 PASS ./pass_fail Please enter your mark: 256 ERROR
rectangle_area.c that reads in 2 integers
which are the side-length of a rectangle, and then prints the area of
the rectangle.
For example:
./rectangle_area Please enter rectangle length: 3 Please enter rectangle width: 5 Area = 15 ./rectangle_area Please enter rectangle length: 42 Please enter rectangle width: 42 Area = 1764
Your tutor may still choose to cover some of the questions time permitting.
