    Hello ,
    Can anyone give me some idea how to start assignment. My assignment is write a program that count how many possition of integer by binary presentation. For example
    If I input 7 then it count 1 1 1 ( 3 positions)
    if I input 9 then it count 1001(4 postions)
    Thanks,
    Sara

    I know its old, but it is a good question

    Example
    Code:
    for(int i = 32; i--;) {
        std::cout << (input & (1<<i))?'1':'0';
    }

    Have you tried the FAQ?

    [edit]And please think of a better thread title next time!
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]
