编译错误：a' : '__int64 [100000]' differs in levels of indirection from '__int64'
          =' : left operand must be l-value
          subscript requires array or pointer type

声明整型变量的时候，为什么不用int？

    __int64 a,b;
    __int64 count;
    __int64 bb;
    __int64 a[100000];
重名了，'a' : '__int64 [100000]' differs in levels of indirection from '__int64' 说得很清楚了呀

把a改成其他的标记符吧，不然 a=a+j;这条语句会出错，编译器不知道你是想使用a,还是a[100000]

两个变量一样的命名，呵呵

谢谢各位亲
