Answer to Question #49711 in C++ for nada
Question #49711
Write C++ program that reads a string that has series of characters (maximum 10 characters), constituting therefore a meaningless string (i.e., the string does not have a meaning). Afterwards, the program asks the user several times the two characters he would like them to be swapped. To this purpose, the user has to specify the positions of these two characters. When the program stops, the user could end-up producing a meaningful string.
