    scanf

    how would i be able to read in two numbers at a time from input with scanf?

    i tried scanf( "%d %d", &x &y ) but it doesnt work like how i want it to.

    i want to read in like:
    100 22
    23 33
    44 55

    so the first row of numbers would be equivalent to one group.
    there are only 10 people in the world, those who know binary and those who dont

    >>while ( scanf( "%d %d", &x, &y ) == 1 )
    scanf() returns the number of successfully read variables, so in your example the desired return code is 2, not 1.

    >>while ( scanf( "%d %d", &x, &y ) == 2 )
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]
