Im getting this error in if-condition for string.

.. and that error is...?


I suspect it's because .at() returns a character and you're comparing it to a string called find. find needs to be a char as on line 15

str.at(j) is a char. find is a string. A char is not a string.

How is it a char? The data type of str1, underscore and find is string.

Can you say what the member function .at() does?
