input with cin....
Hello everybody,
I've just got an assignment, I need to write a program that receives as input an unknown amount of numbers in one line with space after each number, and enter after the last number. I need to get those numbers with the 'cin' command.
How can I do that?
Since I don't know how many numbers, I thought about placing cin in a loop but how can it recognize when the line has ended?
Thank you for you help!!
you could try char by char read in to a char array and convert each char array to a string and then to an int or a float when you've found a space using atoi or atof. Alternatively, you could try calling the peek function to see what the terminating char for each >> call is before calling the next >> since >> doesn't clear the terminating char from the input buffer.
cin>> skips spaces and newlines so i think cin.get() will be better which read char by char
Note: This came from Preludes code example at:Code:#include <iostream> #include <vector> using namespace std; int main() { vector<int> numbers; int num; cout << "Enter a list of numbers and then q and enter to exit: "; while ( cin>>num ) numbers.push_back ( num ); //do something with numbers.. return 0;

This semi solves your problem, but i'm not entirely sure how you would deal with the enter portion of the solution..
