这里写图片描述

#include<vector>#include<iostream>using namespace std;void PRint_vector_info(const vector<int>& array){ cout<<"vector's capacity is "<<array.capacity()<<endl; cout<<"vector's size is "<<array.size()<<endl;}int main(){ int array[10]={0,1,2,3,4,5,6,7,8,9}; vector<int> coll; print_vector_info(coll); /*cout<<"vector's capacity() is "<<coll.capacity()<<endl; cout<<"vector's size is "<<coll.size()<<endl;*/ for(int i=0;i<10;i++) { coll.push_back(i); } /*cout<<"vector's capacity() is "<<coll.capacity()<<endl; cout<<"vector's size is "<<coll.size()<<endl;*/ print_vector_info(coll); cout<<coll[9]<<endl; return 0;}
