hey pratik, what do you want us to do ??.. clarify your doubt.
this question gives you a string “1234” and you have to convert it into integer and then print it.
string “1234” means one two three four
integer 1234 means one thousand two hundered thirty four.

Hey Pratik, in your return statement return (s2 + 10*stringtoint(s2[i]));, you are trying to add a string s2 with an integer 10*stringtoint(s2[i]), and this is not valid in c++. you can add two same data types only.
