look at my code,
what is held in name[7]? a null? or random information?
for example,,,how would i get it to print letter by letter till it reachs the end of my name , rodrigo. ? without directly telling it to stop at name[6]?

Code:

#include <string>
#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
     string name("rodrigo");
     cout << name[7]; 
     getch();
     }

i tried this to find out what name[7] was holding but prints nothing.
-
i have tried this but i have no idea what i was doing,, lol

Code:

#include <string>
#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
     string name("rodrigo");
     for(int x=0; x!=NULL;x++){
     cout << name[x]; 
     endl;
     
     }
     getch();
     }

The string class has a member function that returns the length of the string. use string::size() in a for loop:

Code:

string name = "rodrigo";
for (string::size_type i = 0; i != name.size(); ++i)
{
  cout << name[i] << endl;
}

In yourt first example you forgot that counting strts at zero in programming. So the last letter in "rodrigo" is
name[6].

one more question since i have thread already open

Code:

#include <string>
#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
     string name("rodrigo");
     for(int x=0; x!=name.size();++x){
     cout << name[x]; 
     
     endl; /*putting this endl; makes my program not compile? why?*/
     
     }
     getch();
     }

endl is used at the end of cout statements to make a new line. For example:

Code:

cout << "HELLO" << endl;

You can also use:

Code:

cout << "HELLO\n";

You can also use:

Code:

cout << "HELLO\n";

Or you could use plain

Code:

cout<<endl;
OR cout<<"/n";

The first is suggested since it also clears the stream
