#include "stdio.h"

int main( )
{


    int x,y;

    y=x(5);
    return 0;
}

MSVC 2010编译器给出以下错误：

Error   1   error C2064: term does not evaluate to a function taking 1 arguments    c:\users\ae\documents\visual studio 2010\projects\text\text\text.cpp    13

2   IntelliSense: expression must have (pointer-to-) function type  c:\users\ae\documents\visual studio 2010\projects\text\text\text.cpp    13

这是语义错误还是语法错误？
