Consult the while loop to remove excess input problem-CodePudding

Novice small white, consult two while loops, should remove excess input, but don't know what is the difference between, sometimes 2 also can use way, sometimes it is necessary to use a,
A:

 while (cin & amp; & Cin. The get ()! ) 
='\ n'{
continue; 
}

The second way:

 while (cin. The get ()! ) 
='\ n'{
continue; 
}

For example:

 while (cin. The get ()! ) 
='\ n'{
continue; 
} 
if (! Cin) 
{
break; 
}

With the way two, enter a blank line will be stuck, one must use way,

CodePudding user response:

Cin. The clear ();
Cin. Sync ();

CodePudding user response:

While (cin & amp; & Cin. The get ()! )='\ n' & amp; & In front of cin the purpose which teachers explain to help? Is not effect removed in some places, there are times when you must write. A little hard to understand, thank you very much
