The following is a partial listing of a C program to handle Interrupts. If the program runs without errors, indicate the numbers of all the sentences where a Ctrl$-$C command can terminate the process by preventing that sentence to execute. Namely, if Ctrl$-$C is pressed just before sentence X is executed, will that sentence run? If not, X should be part of your answer.
