Decimal to Binary

	scanf("%d",&n);

RE:Decimal to Binary

If you want, you could code you own 'bitset' function for C. Basically, bitset(d) outputs 'd' into binary, showing 'x' bits (so if you output bitset(5), it outputs 0000000101). Though the problem with that is it only converts to binary.

Good job though.

Two possible improvements:

1) Eliminate the use of the `pow' function, which isn't needed.

2) Write a version which works for all integers n that can be represented as C ints. Currently this program only works for small nonnegative integers.

Re: Decimal to Binary

a better one would be

#include 

int main()
{
	int n;
	printf("Please input the integer you want to convert to binary:");
	scanf("%d", &n);
	int i;
	for(i=0; i
