c++

Can someone explain these rules to me in more layman terms? Also, where would we place the cin.ignore (n, pattern) in the program above?

Thanks!

#include #include-: st ring using namespace std; //There are a number of different tools we can access the standard input stream. The following are the two we'll use in this class: //1) The cin > var; command accesses input characters, ignores whitespace, and ignores the newline at the end of the user's input //we use this for gathering numerical input, and storing it in variable "var" //2) The getline(cin, s) command consumes all characters up to, and including, the new line character. //It then throws away the new-line, and stores the resulting string in s. We use this for gathering string inputs. [Requires the string library] /Although the 2 different input gathering tactics seem pretty straightforward,theres 1 issue with using cin >> var; and then after using getline cin, s) //Since cin var leaves a newline, and getline(cin, s) consumes all characters up to and including a new line, //using the first before the second will cause the leftover newline character to be interpretted as hitting enter without any text on the second /To illustrate this problem, see the following example: int main () { string inputString; int inputInt; cout
