部分代码

char zifu1[] = "Public Places   ";
char zifu2[] = "Class Now       ";
char zifu3[] = "No admittance   ";
char *zifu[] = { zifu1, zifu2, zifu3 };
char juti_L[3] = { 16, 16, 16 };char zifu12[] = "No Smoking      ";
char zifu22[] = "Quiet Please    ";
char zifu32[] = "Staff Only      ";
char *zifu22a[] = { zifu12, zifu22, zifu32 };
char juti_L2[3] = { 16, 16, 16 };int main(void)
