int main(void)
{
    char buffer[256];

    printf("Enter your name and press <Enter>:\n");

    printf("\nYour name has %d characters and spaces!",
        strlen(buffer));
   
    getch();

}
下面是提示的错误
F:\Microsoft Visual Studio\MyProjects\lianxi2625\lianxi2625.c(9) : error C2198: 'fgets' : too few actual parameters
F:\Microsoft Visual Studio\MyProjects\lianxi2625\lianxi2625.c(14) : warning C4013: 'getch' undefined; assuming extern returning int
执行 cl.exe 时出错

搞不懂是为什么，和书上一模一样的啊！
