Can't cout vector<string>

[Peithon]

Hi,

I'm trying to create a vector of strings and print the contents using
an iterator but I'm getting
an error with my very first string.

Can anyone help?



#include <iostream>
#include <cstring>
#include <vector>

using namespace std;

int main()
{

char* temp1 = NULL;


vector<string> vec;
vector<string>::iterator it1;


temp1 = new char[21];
strcpy(temp1, "Test String");

vec.push_back(temp1);

for(it1 = vec.begin(); it1 != vec.end(); it1++)
{
cout << "Test: " << *it1 << endl;
}


}

#include <iostream>
#include <cstring>

<cstring> is C's string header. strcpy, strcmp, etc... It does not include
C++'s std::string. Add the line:
#include <string>

and it should compile.

#include <vector>

using namespace std;

int main()
{

char* temp1 = NULL;


vector<string> vec;
vector<string>::iterator it1;


temp1 = new char[21];
strcpy(temp1, "Test String");

vec.push_back(temp1);

for(it1 = vec.begin(); it1 != vec.end(); it1++)
{
cout << "Test: " << *it1 << endl;
}


}

It looks ok. What error do you get?

#include <iostream>

ah ok, you didn't #include<string>.

Hi,

It would help if you told us what the error is....

#include <iostream>
#include <cstring>
#include <vector>

using namespace std;

int main()
{
char* temp1 = NULL;

vector<string> vec;
vector<string>::iterator it1;

temp1 = new char[21];
strcpy(temp1, "Test String");

Why bother with playing with dynamic memory?

vec.push_back(temp1);

Why not just:

vec.push_back("Test String");
