cin problem

[fellow]

Hi,
my problem: cout << "number:" << flush;
cin >> Nr;

if I don't comment this lines I can't read sentence One! Read something about flush, but I don't know how to use it properly.

#include <cstdlib>
#include <iostream>

using namespace std;

/*
 * 
 */
int main() {
    char One[256], Two[256];
      int Nr;
      
//      cout << "number:" << flush;
//      cin >> Nr;
//      
      cout << "sentence One: ";
    cin.getline (One,256);
    
    cout << "sentence Two: ";
    cin.getline (Two,256);
    
    cout << One << " " << Two; // << " " << Nr << endl;
}

kind regards

the >> operator doesn't remove the newline from the buffer so when you call getline(One,256) it finds the newline in the buffer and returns immediately. To remedy this you could use cin.ignore(256,'\n'); after the 'cin >> Nr;'
