Question

I want to display my decimal number as bits.

int g = 2323;

for (int i = 31; i>=0; i--) // int has 32 bits
{
    Console.Write(((g >> 1) & 1) == 1 ? "1" : "0"); // shift right 1 and display it
    g = g / 2; // shift right= divide by 2
}

However this display the number like mirror ( 12345 -> 54321)

I could shift left from the left but then : I might get exception ..(too big number)

What should i need to change in my code to display it correct but :

1. no convert(…) method
2. no insertion to middleman array
3. no recursion.

Is there anything ?

Just off the top of my head:

int g = 2323;

for (uint mask = 0x80000000; mask != 0; mask >>= 1)
    Console.Write(((uint)g & mask) != 0 ? "1" : "0");
