  • 第3题:

    有如下函数模板定义: template T1 fun(T1 a1) { return(al+a2+a3);

    有如下函数模板定义: template<typename T1,int a2,int a3> T1 fun(T1 a1) { return(al+a2+a3); } 则下列调用中正确的是( )。

    A.fun<int,4,3>(5);

    B.fun<4,3>(5);

    C.fun<int,int,int>(5);

    D.fun(5);


    正确答案:A
    解析: 类模板是类的抽象,类是类模板的实例。在调用时,尖括号内指定实际的类型名,在编译时,编译系统就用int取代类模板中的类型参数,这样就具体化了类模板。其中的参数为4,3。

  • 第18题:

    要求80C51五个中断源按下列优先顺序排列,判是否有可能实现?若能,应如何设置中断源的中断优先级别?若不能,试述理由。 ①T0、T1、INT0、INT1、串行口 ②串行口、INT0、T0、INT1、T1 ③INT0、T1、INT1、T0、串行口 ④串行口、T0、INT0、INT1、T1 ⑤INT0、INT1、T0、串行口、T1


    正确答案: ①T0、T1、INT0、INT1、串行口:能。T0、T1为高优先级,其余为低优先级。
    ②串行口、INT0、T0、INT1、T1:能。串行口为高优先级,其余为低优先级。
    ③INT0、T1、INT1、T0、串行口:不能。80C51只有两个中断优先级。当设置INT0、T1为高优先级时,INT1、T0、串行口处于同一低优先级,而T0的优先权排在INT1之前,INT1无法优先T0。
    ④串行口、T0、INT0、INT1、T1:不能。80C51只有两个中断优先级。当设置串行口为高优先级后,T0、INT0、INT1、T1处于同一低优先级,而INT0的优先权排在T0前面,T0无法优先INT0。
    ⑤INT0、INT1、T0、串行口、T1:不能。80C51只有两个中断优先级。当设置INT0、INT1为高优先级后,T0、串行口、T1处于同一低优先级,而T1的优先权排在串行口前面,串行口无法优先T1。
