程序出现段错误

[nonego]

一个c++primer的习题，4.35题。运行时是段错误，大家看看是怎么回事，用gdb调试可以看出是到最后cout时出现段错误
题目要求是输入几个字符串，然后用字符数组保存，然后把字符数组的指针存在一个字符指针数组里。
#include<iostream>
#include<string>
#include<vector>
using namespace std;
int main()
{
string s;
vector<string> vec;
while(cin>>s)
{
vec.push_back(s);
}
char **str=new char*[vec.size()];
for(vector<string>::iterator iter=vec.begin(),end=vec.end()
;iter!=end;iter++)
{
char *ss=new char[(*iter).size()+1];
for(string::size_type i=0;i!=((*iter).size());i++)
{
ss[i]=(*iter)[i];
}
ss[(*iter).size()]='\0';
*str=ss;
str++;
}
int size=vec.size();
for(int i=0;i<size;i++)
{
cout<<str[i]<<"";
// delete [] str[i];
}
cout<<endl;
delete [] str;
return 0;
}

str的地址被修该了
设置个中间量

#include <iostream> 
#include <string> 
#include <vector> 
using   namespace   std; 
int   main() 
{ 
	string   s; 
	vector<string>   vec; 
	while(cin>> s) 
	{ 
		vec.push_back(s); 
	} 
	char**str = new char*[vec.size()]; 
	char** pTmp = str;
	for(vector<string>::iterator   iter=vec.begin(), end = vec.end() ; iter != end; iter++) 
	{ 
		char*ss = new   char[(*iter).size()+1]; 
		for(string::size_type   i=0;i != ((*iter).size()); i++) 
		{ 
			ss[i]=(*iter)[i]; 
		} 
		ss[(*iter).size()]= '\0';               
		*pTmp = ss;
		pTmp++;
	} 
	int  size=vec.size(); 
	for(int  i=0;i <size;i++) 
	{ 
		cout << str[i] << " "; 
		// delete   []   str[i]; 
	} 
	cout <<endl; 
	delete   []   str; 
	return   0; 
}

把你原来注释的补上，否则会内存泄露

//书写问题，<<和>>用半角，别用全角

#include <iostream>
#include <string>
#include <vector>
using namespace std;
int main()
{
string s;
vector <string> vec;
while(cin>> s)
{
vec.push_back(s);
}
char **str=new char*[vec.size()];
for(vector <string> ::iterator iter=vec.begin(),end=vec.end()
;iter!=end;iter++)
{
char *ss=new char[(*iter).size()+1];
for(string::size_type i=0;i!=((*iter).size());i++)
{
ss[i]=(*iter)[i];
}
ss[(*iter).size()]= '\0 ';
*str=ss;
str++;
}
int size=vec.size();
for(int i=0;i <size;i++)
{
cout<<str[i]<<" ";
// delete [] str[i];
}
cout<<endl;
delete [] str;
return 0;
