replace a character in a string using at function?

Ask Time：2012-08-14T16:43:33 Author：Swapp Sawant

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??

ecatmur :

replace has no overload taking size, size, char. You want\n\nCorrAns.replace(1, 1, 1, OtherString.at(pos));\n\n\nor\n\nCorrAns.replace(1, 1, OtherString.substr(pos, 1));\n",

James Kanze :

Just use at (or the [] operator) accross the board:\n\ncorrAns[1] = otherString[pos];\n\n\n(Note that at rarely has the semantics you want. If a bounds error is\na precondition failure, as is usually the case, the last thing you want\nis an exception.) ",

Your syntax is wrong. There are several methods for replace() function. Check below :\n\nhttp://www.ansatt.hig.no/frodeh/ooprog/string2.html",
