Thank you for explaining the difference between cin.getline() and getline()!

[typical_yt]

for people whos getline doesn't work for seemingly no reason, use cin.ignore() before calling it. worked for me.

It can be used to get a line from a file too. I believe.

Here is a question for Curry - scope resolution operator :: is used for cin, cout, string. I can understand that. But getline is used without scope resolution operator. Compiler accepts the same. It is not expecting istream::getline. Why is it so? Thanks in advance. Your teaching is a really good for C++ programmers.

What If you have two getline() functions in a row;

example:
cout << "Enter name: ";
getline(cin, name);

cout << "Enter address: ";
getline(cin, address);

it skips the next getline. and doesn't prompt for user input.

Hey Caleb, had a question. At the start you'd declared 'greeting' and then 'left_over'. Then, you took the input as 'Hello World' which were stored as greeting=Hello and left_over=There. I did the same where I declared 'firstword' and 'secondword' and took the input as 'Hello There' and printed them in the order 'firstword' and then 'secondword' but what I'm getting as input is first 'There' and then 'Hello' meaning 'There' was stored in firstword and 'Hello' in secondword. I don't know why that's happening. Can you help?

With this the only way I could pull off the user input being beside each other was to implement the (;) at the beginning of the std::cout

cool explanation.. i am unable to use 'cin.getline()' .. i am getting an error like ' no matching function for call to '.. i have searched for it.. in geek for geeks, they have mentioned it will take 2 or 3 parameters and 3rd parameter being the delimiter.. 3rd parameter is optional.. 2nd is the max size and 1st is the variable.. but they have used C character array here but not a string variable.. sir, could you please explain it to me? How can we use '.getline()' in c++?

[kishoresk]

sir iam using for visual studio but not working getline () .getline() function identifier not found .pls give me a solution

[hesham]

Would that work with C-string, I mean if I want to input a C-string which is considered an array of course and it has spaces would I use getline also or is there any other way?

[kenneth]

how about the space? cin automatically ignores them??

[aniketshirke]

int main(){
int t{};
cout<<"enter how many time do u want this to happen\n";
cin>>t;

while(t--){
string s1{};
cout<<"enter s1 : "<<endl;
getline(cin, s1);
cout<<"my string input for loop : " <<t<< "is "<<s1<<endl;
}
}
//whats wrong here : the getline function dont work for the first iteration .
//i have started c++ a week before and trying to figure out how strings work in c++ .so this is just sample code to test getline function .

[mohammad_bilal]

use
using namespace instead of writing std every tim, e

[andrewgreen]

Is anyone else's getline skipping the first word too?

[PunmasterSTP]

I think it would be a cin not to learn about C++ IO.
