你这里面有错误哦！！！

我粘贴了一下，怎么有好多错误啊！！！

说有错误的同学多半是自己的编译器或者编译方法错了,其实就是把自己第一个"hello world"的空程序代码给覆盖掉再编译就欧克可以开始play了

不错

有一个错误，运行不了

怎么覆盖，求解

D:\计算机语言软件\11.c(1) : warning C4067: unexpected tokens following preprocessor directive - expected a newline
D:\计算机语言软件\11.c(2) : error C2449: found '{' at file scope (missing function header?)
D:\计算机语言软件\11.c(23) : error C2059: syntax error : '}'
执行 cl.exe 时出错.

11.exe - 1 error(s), 0 warning(s)
什么情况呢

你确定你是在win32控制应用平台下运行的不

强 ，
