For additional information, see the C# Language Specification. So &command is not a pointer-to-a-pointer, so assigning &command to msg is not valid (and my compiler doesn't even compile it). This iteration returns a value of 3, and the current location in the iterator method is retained. For C-string (char []) you should do something like this: char mystring[] = "My String"; int size = strlen(mystring); int i; for(i = 0; i < size; i++) { char c = mystring[i]; } For std::string you can use str.size() to get its size and iterate like the example , "; for (std::size_t i = 0; i < str.length (); ++i) std::cout << str [i]; how to iterate through char array You iterate while the read character is not the null character. you can have a loop on the entered character, until the entered character is enter (Ascii code 13) char c; while ( (intVal = (int)cin.get (c)) != 13) { do processing on the character 'c' } How to iterate over the elements of an std::tuple in C++, Different ways to iterate over a set in C++.
