[FIXED] Typed string::length(). I got "Unable to resolve identifier length"

Issue

Using Win8.1 system. Using NetBeans IDE for C++ programming because it offers an easy way to make simple windows.

Code:

#include <cstdlib>
#include <iostream>
#include <ctime>
#include <string>

using namespace std;


int main(int argc, char** argv) {

    srand(time(NULL));

    int seed_component0 = rand();

    string Player_name;
    string seed_component1;

    int i = 0;

    cout << "Please, enter your player name: ";
    cin >> Player_name;
    while (i < Player_name.length()){

        seed_component1.append(int(Player_name[i]));
        i++;
    }

    string seed = seed_component0 + seed_component1;

    cout << endl << "The seed we will use is " << seed << endl;


    return 0;
}

That's just the main file, I only created a new project and tried to do that, but when I tried to run it it threw "Unable to resolve identifier length" I also tried with size(). It just doesn't know what that is.

Also I have another error that doesn't affect the program, at least for now; in the include lines, it says"Library file (path) but there is an unresolved #include < stddef.h > in included file (path) wctype.h"

I am using MinGW as the compiler.

Edit: I also wanted to use to_string() and it didn't work either.

Solution

I tried to use sstream instead of to_string() for conversion. I also replaced your while loop with a for loop. The size() works for me though

Just take a look at http://www.cplusplus.com/articles/D9j2Nwbp/ which is about converting numbers to strings and vice versa

#include <cstdlib>
#include <iostream>
#include <ctime>
#include <string>
#include <sstream>

using namespace std;

string IntToString(int Number)
{
    ostringstream ss;
    ss << Number;
    return ss.str();
}

int main(int argc, char** argv) {

    srand(time(NULL));

    int seed_component0 = rand();

    string Player_name;
    string seed_component1;

    int i = 0;

    cout << "Please, enter your player name: ";
    cin >> Player_name;

    int name_length = Player_name.size();
    for(int i = 0; i < name_length; i++)
    {
        seed_component1 += IntToString(int(Player_name[i]));
    }

    string seed = IntToString(seed_component0) + seed_component1;

    cout << endl << "The seed we will use is " << seed << endl;


    return 0;
}
