I offer the following as a "Cocoa solution" to the OP's query,
whatever that might be taken to mean...
(For extra credit: why must the parameter be unsigned?)
Tom Wetmore
NSString* binaryRepresentation (NSUInteger number)
{
unichar buffer[64];
NSUInteger n = 0;
while (number) {
buffer[n++] = (number & 1) + '0';
number >>= 1;
}
NSInteger i = 0, j = n - 1;
while (i < j) {
unichar temp = buffer[j];
buffer[j] = buffer[i];
buffer[i] = temp;
i++, j--;
}
return [NSString stringWithCharacters: buffer length: n];
}
