我想在 C++的算法库中使用sort() 。我只能找到排序向量的示例,因此我试图通过初始化数组来初始化向量。执行时出现分段错误,无法弄清楚我编写的代码中有什么问题。
#include <cmath>
#include <cstdio>
#include <vector>
#include <iostream>
#include <algorithm>
using namespace std;
int main() {
int n,k,packet[1000],min=0;
scanf("%d",&n);
scanf("%d",&k);
for (int i = 0; i < n; ++i)
{
scanf("%d",&packet[i]);
cout<<i<<endl;
}
cout<<"debug";
vector<int> packets(packet,packet+n);
vector<int>::iterator start,stop;
sort(packets.begin(),packets.begin()+n);
min=*(packets.begin())- *(packets.end());
cout<<min;
for (vector<int>::iterator it=packets.begin(); it!=packets.end()-k; ++it)
{
printf("%d ",*it );
if((*(it+k) - *it)<min)
{
start=it;
stop=it+k;
}
}
printf("%d\n",*stop- *start );
return 0;
}
