Q53

Consider the following program snippet. Assume that the program compiles and runs successfully. Further, assume that the fork() system call is always successful in creating a process. int main () { int i; for (i = 0; i < 3; i++) { if (fork() == 0) { continue; } break; } printf("Hello!"); return 0; } The total number of times that the printf statement gets executed is $\_\_\_\_$.
