Why do I need to press enter twice to proceed?

Question

Everything is working fine in this program except when it reaches line "cout<<"From Date: ";. At this point no matter if i give input or simply hit enter without input I have to hit enter twice to proceed further. I tried removing cin.ignore() but it causes more problem by jumping over the first getline(). Here is the snippet which is causing this problem-

void Date :: diffbw(){
Date current, ref;
string choice;
cin.ignore();
cout<<"\n Type 'man' to enter date manually else hit Enter to insert current date!";
do{
cout<<"\n\n From Date:";
getline(cin, choice);
if(choice == "man")
current.getdate();
else if(choice.empty())
current = sysDate();
else{
cout<<"\n Wrong Choice!";
cout<<"\n Enter Again?(y/n): ";
getline(cin, choice);
}
} while(choice == "y" || choice == "Y");

Answer 1

I don't know what your program does before executing this piece of code, nor I know C++🙄
But since cin.ignore(); ignores just a character, have you tried something like that cin.ignore(999, '\n'); instead?

In any case your problem is probably just a new line left in the buffer.

Davide yes i have already tried that syntax of cin.ignore(). Also i think this snippet is enough to describe the problem and remaining program has no part in it. Anyways this function is simply called from a switch statement.
