C++_输入一段数据到向量vector里面

#include<vector>
using namespace std;
vector<char>Vecprog;
int main()
{
    char ch;
    cout<<"please input test program:"<<endl;
    ch=getchar();
    int i=0;
    while(ch!='#')
    {
        Vecprog.push_back(ch);
        ch=getchar();
        i++;
    }
    for(int j=0;j<Vecprog.size();j++)
        cout<<Vecprog[j];
    return 0;
}
