C#include <stdio.h> int main { int x = 10; printf("The value of x is: %d \aand it cannot be changed!\n", x); return 0;}What is the likely consequence of the escape sequence in this code?
Correct answer: C. The terminal might produce a beep sound after printing the value of x
- A. The program will crash
- B. The phrase "and it cannot be changed!" will be deleted
- C. The terminal might produce a beep sound after printing the value of x
- D. No visible effect; the \a will be ignored
Explanation
The behavior of \a (alert/bell) is system-dependent. In many terminals, it produces a beep or a sound alert. However, some modern terminals might simply ignore it.
