第5题:

下面程序的输出结果是______。 include using namespace std; int x; void funA(int&am

下面程序的输出结果是______。

include<iostream>

using namespace std;

int x;

void funA(int&,int);

void funB(int,int&);

int main()

{

int first;

int second=5;

x=6;

funA(first,second);

funB(first,second);

cout<<first<<””<<second<<””<<x<<endl;

return 0;

}

void funA(int &a,int b)

{

int first;

first=a+b;

a=2*b;

b=first+4;

}

void funB(int u, int &v)

{

int second;

second=x;

v=second+4;

x=u+v;

}


正确答案:10 10 20
10 10 20 解析:本题考核函数的引用传递。“引用”实际上是给一个已知变量起个别名,对引用的操作也就是对被它引用的变量的操作。函数funA的功能是将第二个实参的值乘以2再赋值给第一个实参(通过引用传递实现),函数funB的功能是将全局变量x加上4再赋值给第二个实参,同时x等于第一个实参与第二个实参相加的和。

第6题:

数据传输速率是描述数据通信的基本技术参数之一,它的单位是 ______ 。

A.bit/second(bps)

B.Byte/second(Bps)

C.KByte/second(KBps)

D.MByte/second(MKBps)


正确答案:A
解析:数据传输速率或称数据率是描述数据通信的重要技术参数之一。它是指每秒传输的二进制代码(比特)位数,单位为比特/秒(bit/second,bps)。如果一个电脉冲信号只有“0”和“1”两个状态,即一个电脉冲信号表示一个二进制数位(比特),设T为传输的电脉冲信号的周期。则:数据传输速率S=1/Tbps
如果一个电脉冲信号有4种、8种或更多可能的状态数,即一个电脉冲信号可以表示2个,3个或更多个二进制数位(比特),则:数据传输速率S=1/T(log2N)bps
其中T为传输电脉冲信号的周期,N为电脉冲信号所有可能的状态数。由此可见,数据率的高低,不仅和一位数据所占的时间宽度有关,还和电脉冲信号可能的状态数有关。注意:单位bps中的“b”是指bit,而不是指byte。
