String to Int How?

[JasonLpz]

is this the proper way?

5. How to convert a string to a number?

- Use the atoi function to convert a string to an integer.

Example:

---------------------------------------------------------------------------------------------------------------------------

#include <iostream> //preprocessor statement

#include <stdlib.h> //contains itoa & atoi

using namespace std; //choosing the namespace that we are going to use



int main() //this is where the program starts executing

{

char buffer[20];

int i = 3445;

_itoa( i, buffer, 10 );

cout<<buffer<<endl;

return 0;

}

Is that the way its the same as he has for the Int to String. I found this in the main tutorial link
I Tried using the below

char buffer[20]; 
                          char buffer2[20]; 
                          
                          ::GetWindowText (edit,buffer,255);
                          ::GetWindowText (edit,buffer2,255);
            
                          int i = buffer;
                          int i2 = buffer2;
                          int i3 = i + i2;    
 
                        _itoa( i, buffer, 10 );
                        _itoa( i2, buffer2, 10 );
