当我编译C使用VS2012 C ++时，它总是在行显示错误C2143 54，错误C2065在第55行。但如果我在FILE * pfile = _popen（cBuff，"r"）之前重新定义了char cRecvBuff [512]，那就行了，没有错误显示。可以
任何人都可以帮助我吗？抱歉，我是C节目的全体新人。

when i compile the C use the VS2012 C++, it always shows the error C2143 at line 54,and error C2065 at line 55. but if i redefine the  char cRecvBuff[512] before the FILE *pfile = _popen(cBuff,"r"), that's works and no error shows. can anybody can help me? sorry i am total fresh man to the C programme.

在C中（不像C ++），所有变量都必须在任何语句之前在块的开头声明。

In C (unlike C++), all variables have to be declared at the beginning of a block, before any statements.
