Exercise 1
Create a C-program that reads the characters from the keyboard and shows them on
screen (the inputted characters should only be displayed when the user hits ‘enter’, line
by line).
When ^A is entered, the program must end properly. Then the following message will
appear: “CTRL + A is a correct ending.”
Tip: getchar() reads and putchar() writes the type int. The value of ^A is 1.
Exercise 2
Alter the last program of exercise 1 in such a way that the output doesn’t go to the screen
but is written to a file. The file to write to must be specified by the user.
