对于如下C语言程序 int main() { pid_t pid; int x=1; pid = fork(); if(pid==0) printf("I am the child process, x=%d\n", ++x); else printf("I am the parent process, x=%d\n", --x); } 在UNIX操作系统中正确编译链接后，其正确的运行结果是

A.I am the child process, x=2

B.I am the parent process, x=0

C.I am the parent process, x=2

D.I am the child process, x=0

对于如下C语言程序在UNIX操作系统中正确编译链接后，其正确的运行结果是()

A.I am the child process, x=2

B.I am the parent process, x=0

C.I am the parent process, x=2

D.I am the child process, x=0

请分析以下程序。 int main() { pid_t pid; pid = fork(); if(pid==0) printf("I am the child process, my process ID is%d\n",getpid()); else printf("I am the parent process, my process ID is%d\n",getpid());} 那么，该程序正确运行后的结果是

A.I am the child process, my process ID is 3744 I am the parent process, my process ID is 3987

B.I am the child process, my process ID is 3744

C.I am the parent process, my process ID is 3987

D.不输出任何信息
