Hi, im making a program to convert any number to binary using the division method. Its just dividing the number by 2 and saving the remainders (which will either 1 or 0 ).

At first I tought of just printing out the remainder saved in the variable rem, but there were some problems with 1 digit numbers, and the remainders are not in the correct order. For example the remainders of 10 are: 0101, but this of course isnt 10 in binary, you would have to start with the las bit, and go backwards, so it would be 1010.

So later i thought, why not putting the remainder inside an array? So thats what i did.

heres what i wrote:

ok, here is my question: If the number is 10, there are 4 elements in the array (0101), but i cant know that the number is 10, because its the user who has input that number so i cant know how many elements have been used in my array. How can i program this thing to print in the screen all the elements of the array, without knowing how many elements are there ( i cant do this: cout<< rem[0]<<rem[1]...), and how can i reverse that order, so that the last element is the first one.Code:

...

int rem[100];

int i;

int n;

...

...

i = n;

c = 0;

while ( i > 2)

{

a = n / 2;

rem[c] = n % 2;

n = a;

i--;

c++;

if ( n == 0)

{

break;

}

}

Maybe its a stupid question, but im studying this for the first time :)

waiting anxiously for your answer!! thanks in advance.
