how to know how much we need to put in the cin.ignore ? for example :-
char name[55];
int id;
int main (){
cout<<" Enter your name : ";
cin.getline(name,54);
cout<<" Enter your ID : ";
cin>>id;
cout<<" Your name is : "<<name<<endl;
cout<<" Your ID is : "<<id;
return 0;
}
if I don't put cin.ignore, the output for ' Your ID is :' will be short
and if I put cin.ignore like this :-
char name[55];
int id;
int main (){
cout<<" Enter your name : ";
cin.ignore(24,'\n');
cin.getline(name,54);
cout<<" Enter your ID : ";
cin>>id;
cout<<" Your name is : "<<name<<endl;
cout<<" Your ID is : "<<id;
return 0;
}
the output will be much worse, both name and id are wrong
can someone explain to me please ?
