| Post subject: | converting decimal to binary using functions |
i have a fairly good understanding of functions, but i have no clue on how to start this. im thinking of doing it by getting each number, and using its modulus, and printing it out, but i need to have it so that it displays the binary output in numbers of 8 How would I do each number say if the user enters 845, getting 5, then 4, then 8, and depending on how many number inputed, it would only do it for that many numbers. such as 2 would be 00000000 00000000 00000000 00000010 any help would be greatly appreciated |

let n be an integer n % 2 will return the last binary digit n >> 1 will shift n one to the right (dropping the last binary digit) thus you just need to loop 32 times, saving n%2 and then shifting n one to the right. At the end you can format your string however you want. |

would i use a for loop to save it 32 times? i'll post up a code of what I have so far |
