连续整数

题目要求:

输入一个数组 判断数组中的元素是不是连续的整数

程序:

#include<iostream>
#include<vector>
using namespace std;
class continuum
{
private:
vector<int> ori_num;
int tot;
int len;
int mid;
int sta;
vector<int> cal_rul;
public:
continuum();
~continuum(){}
void bui();
bool res();
};
continuum::continuum():tot(0),len(0),mid(0),sta(0)
{
}
void continuum::bui()
{
cout<<"enter the whole vector"<<endl;
int tem;
while(cin>>tem)
{
ori_num.push_back(tem);
tot+=tem;
len++;
cal_rul.push_back(1);
}
mid=int(tot/len);
sta=mid-int((len-1)/2);
}
bool continuum::res()
{
bool arg;
int cal=len;
for(int i=0;i<len;i++)
{
cal-=cal_rul[ori_num[i]-sta];
cal_rul[ori_num[i]-sta]=0;
}
arg=(!cal);
return arg;
}
int main()
{
continuum con;
con.bui();
switch(con.res())
{
case true:cout<<"true";break;
case false:cout<<"false";break;
}
return 0;
}
