cout << val << endl;
cout << "char is: " << ch << endl;
cout << (int)ch << endl;
cout << "string is: " << str << endl;
cout << "string size: " << strlen(str.c_str()) << endl;
stringstream itost;
itost << str;
int x;
itost >> x;
cout << "to i: "<< x << endl;
cout << stoi(str.c_str()) << endl;
return 0;
}
