Question 1 Write a program in C which first initializes an integer variable to a random value between 100 and 200. By using signal() system call for SIGINT, alter the behaviour of Ctrl-C such that whenever this combination is pressed, the program switches between adding or subtracting 10 from this variable in an endless loop with 1 second delays. Your program must indicate whether it is increasing or decreasing the variable and it must end if value of the variable is below 100 or above 200.
