Question 1 Sample Run Write a program in C which continuously $ ./question1 Enter a number: 3 takes integer inputs from the user with Enter a number: 7 scanf function. By using signal() system call <CTRL-C> for SIGINT, alter the behaviour of Ctrl-C Inputs: 2, Average: 5 such that whenever the combination is Enter a number: 12 Enter a number: 4 pressed, the program responds with the Enter a number: 14 number of inputs and their average value Inputs: 5, Average: 8 <CTRL-C> on screen. Use -1 to exit. Question 2 process must count the numbers. Both Execute the following command to create a child processes must print their results on "data.txt" 100.000 screen. In the meanwhile, parent process must display child process ID's on screen and wait for both processes to end. file which contains random letters and numbers: cat /dev/urandom | tr -dc 'a-z0-9' | fold -w 100000 | head -n 1 > data.txt Sample Run $ ./question2 Now write a C program which creates two [PARENT] Child process ID: 3587 child processes. The first child process [CHILD1] Number of letters: 58392 must count the letters, while the other child [PARENT] Child process ID: 3588 [CHILD2] Number of numbers: 41608
