Example:

Consider the problem of replacing all straight quotes "like this" with curly quotes "like this" in a string. Before embarking on this task, let's think of a reusable method. Suppose we know where the straight quote is. Then we want to replace it. That would be useful in other situations too Your task is to complete the function replace_at that replaces the character at a given position with an arbitrary string Complete the following file strings.cpp #include 2 using namespace std; 3 4 * Replaces a character of a string at a given position. aparam str the string where the replacement takes place @param position the position of the character to be replaced @param replacement the replacement string 6 7 9 return str with the character at the position changed to 10 the replacement string, or the original string if position was not valid 12 * 13 string replace at (string str, int position, string replacement) 14 15 16 17 Submit Consider the problem of replacing all straight quotes "like this" with curly quotes "like this" in a string.
