C++问题求解答
如果所有的变量被定义,并申明了以下程序,函数fun（）中用到的变量有：
#include
void fun(int x)：函数：fun
void main( )：主函数
答案：A
就是题有点难懂，看懂了就好做了。
希望对你有帮助！
c++难题，求解答！！！
#include <iostream>
using namespace std;
class Rectangle{
public:
Rectangle(int l, int w):length(l), width(w){
}
int Area(){
return length*width;
}
protected:
int length;
int width;
};
class Cuboid:Rectangle{
public:
Cuboid(int l,int w, int h):Rectangle(l,w), height(h){
}
int Vol(){
return Area()*height;
}
void Show(){
cout<<"length:"<<length<<",width:"<<width<<",height:"<<height<<",vol:"<<Vol()<<endl;
}
private:
int height;

c++问题求解
第一题：若short num = 10; //num的地址为0x1234 short *p = # //p的地址为0x1230 则printf("%p",p+1)最后输出的数为多少？
0x1232
第二题：若short num=10; short *p = #
则p,&num,&(num+1),*p,num+1,*num,&num+1各为多少？
p是一个地址，值为num的地址，
&num 10的存放地址
&(num+1) 这应该是错的吧
*p ＝ 10
num+1 ＝ 11
*num 无效,
&num+1 不知为何值
第三题：若int x[10];
int *p = x; 则*(x+i),x[i],p+i,p[i]中，有哪个的意义是不同于其他三个的？
*(x+i)这个不同于其它，
