用iPad打的 有的符号可能不准确 建议改一下符号
#include"stdio.h"
void main()

for(i=0; i<100; i++)

//输出

楼主说的是不是容器呀
#include <iostream>
#include <vector>
using namespace std;
int main ( )
{
vector<int> IntVec;
int iVal;
while (cin >> iVal)
IntVec.push_back (iVal);
vector<int>::const_iterator CIter = IntVec.begin ();
while (CIter != IntVec.end ())
cout << *CIter++ << endl;
}
我晕 答完才发现是C语言 哎
#include <stdio.h>
