To do: Using the ignore() and get() member functions of the cin in C++ programming

To show: How to use the cin get() and ignore() member functions to extract and discard a stream in C++ programming

// the istream cin. ignore() and cin.get() member functions

#include <iostream>

using namespace std;

int main (void)

{

char firstword, secondword;

cout<<"Enter your first and last names: ";

// read and store in firstword, get() function includes white-space characters

firstword = cin.get();

// extracts up to 30 elements and discards them, a space, if encountered before 30,

// causes ignore() to return and

cin.ignore(30,' ');

// allowing all elements after a space to be read.

secondword = cin.get();

cout<<"The initials letters are: "<<firstword<<secondword<<endl;

return 0;

}
