c++中泛型算法拷贝复制 copy()函数用法?

Question

# include<iostream>

# include<vector>

# include<string>

# include<algorithm>

using namespace std;

void find1(vector<char>::iterator &pf, vector<char>::iterator &pb);

int main()

{

string str;

vector<char> iv;

getline(cin, str, '.');

cout<<str<<endl;

iv.resize(1 + sizeof(str) / sizeof(char));

//iv.reserve(sizeof(str) / sizeof(char)); // resreve()只分配空间不初始化

copy(str.begin(), str.end(), iv.begin());

/*vector<char>::iterator pb = iv.end();

vector<char>::iterator pf = iv.begin();

for(pf; pf != pb; pf++)

cout<<*pf;

find1(iv.begin(), pb);*/

return 0;

}

Answer 1

就是copy()函数调用出了问题
