String bad pointers in Vector

[forstudy3]

I have following piee of code -

std::string sInput = "http://www.cplusplus.com/forum/post.cgi?w=new&i=854";
	vector<std::string> sStr;
        vector<std::string>::iterator Str_t;
	int c = 0;
	size_t found;
	std::string sTxt =  "";
	
	found = noteText.find_first_of("/");
	while (found!=string::npos)
	{		
		sTxt = sInput.substr(c,found);		
		sStr.push_back(sTxt);
		std::string Temp = sInput.substr(found+2);
		sInput = Temp;
		found=Temp.find_first_of("/");				
	}

In above code I want to retreive text between "/" & strore it in vactor.It is working fine till retreiving correct values but when it inserts string using
sStr.push_back(sTxt);in vector shows <bad ptr> at location 1.After completing I tried to print the values in vector using -

	for (int i = 0;i<sStr.size();i++)
	{
		printf("%s\n",sStr[i]);
	}

It writes <NULL> .
Please let me knwo what I am missing?

Thanks

Firstly when printf says that with a %s parameter it can print a string, it really means a c-string (it's a c function) which is a const char*. With std::string either cout << str or printf(..., str.c_str())

Also, what is noteText ?
