A question on the number of lines

For example
Input:
Each line has two integral numbers, and there are some lines, but I don't know the number of lines. When the program has read the last line, I want it to stop. How can I do that?
I'm a beginner. Thanks.

in C,
you read until EOF, <end of file>

Or simply stated. When I have inputted all the numbers, press ENTER twice, the program will stop. How can I do?

Read the input as string and if the lenght of it is zero it indicates the end of input.
