Need to convert symbol to dec in c++

Question

Using type casting to convert string into integer

string str="123456";
int buffer[str.length()];
for (int i=0; i<str.length();i++)
{
    buffer[i]=(int)str[i];
    cout << buffer[i];
}

Getting following result 495051525354 which is DEC form of Symbol 123456

But i want "123456" as a result. Please help!!

[`std::stoi()`](http://en.cppreference.com/w/cpp/string/basic_string/stol)? — Biffen, Aug 20 '15 at 11:11
You are converting each individual character of the string to type `int` and outputting that value. `49`, `50`, `51`, etc. are all values of those characters. — Captain Obvlious, Aug 20 '15 at 11:14

Got workaround by my self

string str="123456";
int buffer[str.length()];
for (int i=0; i<str.length();i++)
{
buffer[i]=(int)str[i] - 48;
cout << buffer[i];
}
