Question

I have a string CorrAns = “Text”, I want to replace a character at a particular position with a character from another string.
I used the following:

CorrAns.replace(1,1,OtherString.at(pos));

But its giving error, what is the best way to do this??

Answer 1

replace has no overload taking size, size, char. You want

CorrAns.replace(1, 1, 1, OtherString.at(pos));

or

CorrAns.replace(1, 1, OtherString.substr(pos, 1));
