Dec to bin
-
do you doubt it? why so Then check it for urself. I didn't try executing it and still it should work fine for all numbers that are within the int range whether it be 2 or 100.

check in This article[^] how i use a simple CRT function to print an integer in binary ;P here's an hint : ::itoa(the_int, the_dest_buffer, 2)[^];

it won't work for that number because the value being returned is an int and range for int's is upto 32767 and while performing the calculations the number (value "binary" being returned from that function) exceeds the limits. ie why I said that this technique is quick and dirty :) . OPTIMIZE it

does it work for 1024?
void DecimalToBinary(int number) { int value; if(number <= 1) { cout << number; return; } value = number%2; DecimalToBinary(number >> 1); cout << value; } Now it would............ and now don't say that it won't work for a negative number :-> Just do some error handling. I hope that this does work for you :-O

Is it some kind of assignment to you? Anyways here is the code :
int ConvertDecimalToBinary(int i) { int temp = 0 ; int counter = 1; int binary = 0 ; while (0 != i) { temp = i%2; i = i/2; binary += temp*counter; counter*=10; } return binary; }Larsson wrote:
printf("dec: %i bin: ???", i, i);
and yes, printf("dec: %d bin: %d", i, ConvertDecimalToBinary(i)); and this function does have its limitations. -- modified at 7:43 Wednesday 29th August, 2007

did you know that
itoa()was doing that kind of stuff by itself ? ;P

It's a good thing, too. Otherwise you would have quickly realized your function does not "convert" its argument to base-2. The function will need to return some sort of
char*orstringin order to properly represent a base-2 number.

I've noticed a pattern ... Given my timezone in relation to most posts, every morning I read through all last night's posts. There's mostly posts with 10 to 100+ fishing-derby-style replies and then the one lonely reply by DavidCrow (or led mike) at the end with a one line simple solution :) It's like a train wreck - I can't help but read them all LOL
