解析 A项错误,变量名不能含特殊字符;B项错误,不能用数据类型给常量赋值;C项错误,True不是数据类型;D项正确,但需要了解的是连续定义时,只有b是Integer类型,a是可变型.故选:D. VB中变量和常量的定义方式如下:Dim 变量名 AS 数据类型;const 常量名=表达式[,常量名=表达式]....
//int &g=f;不可把常量赋给int型引用 //int &c=3;不可把常量赋给int型引用 int &b=a; const int &d=3;//可以给常量引用赋以常量。 const int &e=a; a++;//a可以修改 //e++;但是定义为常量引用的e就不可以修改。 return ; }
