// C++ Code to explain how
// "cin.ignore(numeric_limits
// <streamsize>::max(),'\n');"
// discards the input buffer
#include <iostream>
 
// for <streamsize>
#include <ios>
 
// for numeric_limits
#include <limits>
using namespace std;
 
int main()
{
    int a;
    char str[80];
 
    // Enter input from user
    // - 4 for example
    cin >> a;
 
    // discards the input buffer
    cin.ignore(numeric_limits<streamsize>::max(), '\n'); //without this it wouldn't write 'a' as an output 
 	
  
    /* Another Alternatives for discarding buffer
    // Discards the input buffer.C++ versions below 11 standards
    fflush(stdin);
    
        // Discards the input buffer and
    // initial white spaces of string
    cin >> ws;
    
        // Discards the input buffer
    cin.sync();
    */
    // Get input from user -
    // GeeksforGeeks for example
    cin.getline(str, 80);
 
    // Prints 4
    cout << a << endl;
 
    // Printing string : This
    // will print string now
    cout << str << endl;
 
    return 0;
}
/*
Input: 

4
GeeksforGeeks
*/
/*
Output: 

4
GeeksforGeeks
*/
