The last line is rather inefficiet:
1) you always do the check so you can do it anywhere. Do it early for an early-out. toHex is expected to have a high chance of zero being passed is most programs anyway.
2) the string == "0" is super inefficient. String compare instead of in? No no!
527. 2016-10-18 12:54:42 ACMer Comments on C/C++ Coding Exercise - Convert a Number to Hexadecimal?:
it is the same because x is unsigned.
528. 2016-10-18 12:47:07 Mani Comments on C/C++ Coding Exercise - Convert a Number to Hexadecimal?:
Yes. so the while loop should be x != 0 instead of x greater than zero.
529. 2016-10-18 12:30:41 ACMer Comments on C/C++ Coding Exercise - Convert a Number to Hexadecimal?:
unsigned means non-negative.
so unsigned integer includes zero.
530. 2016-10-18 12:29:47 Mani Comments on C/C++ Coding Exercise - Convert a Number to Hexadecimal?:
I think x is always greater than zero since is an unsigned integer. Correct me if i am wrong.

Yeah. wordpress comments do not support formatting.
532. 2016-10-18 11:42:32 Carlos Comments on C/C++ Coding Exercise - Convert a Number to Hexadecimal?:
I only noticed now. It got weird with the formatting. I don't know what happened.
You can see the code here:

Thanks! yes, yours look modern.

I also have a similar templated function helper.
constexpr const
array nibleToHexTable {{'0','1','2','3','4','5','6','7','8','9','A','B','C','D','E','F'}};
template
inline const
string to_hexString(const uint8_t* byteArray, const LengthType& SIZE){
string final_str("\0", SIZE*2);
for (LengthType i(0); i > 4];
i+= static_cast(2);
}
return (final_str);
}

to make it stand out. 😛

WHY U NAME FUNCTIONS UPPERCASE??
537. 2016-10-08 17:18:22 ACMer Comments on The Childhood Memory - Subor Famicom Clone SB-486D (Xiao Ba Wang):
Have just fixed the broken Images.
538. 2016-10-08 16:56:42 ACMer Comments on The Childhood Memory - Subor Famicom Clone SB-486D (Xiao Ba Wang):
I sold mine on ebay a few months ago.
You could try aliexpress
539. 2016-10-08 14:52:25 Jesse Comments on The Childhood Memory - Subor Famicom Clone SB-486D (Xiao Ba Wang):
I know this thread is outrageously old but I just bought a SUBOR486 and I'm interested in getting some of these carts that feature BASIC and whatnot. Do you have any advice for finding any of these?
Cheers,
Jesse
540. 2016-10-04 09:41:16 ACMer Comments on How to Disable Onboard Graphics Card?:
I know. you could either (1) use a desktop (2) raise a support ticket to your games
541. 2016-10-04 09:38:55 AHMED ALI Comments on How to Disable Onboard Graphics Card?:
It works fine if I enable the Intel ,but bothers me with games and applications that looks at the Intel card as the only card there
This double card thing sucks
542. 2016-10-04 09:02:31 ACMer Comments on How to Disable Onboard Graphics Card?:
maybe your nvidia is damaged?
543. 2016-10-04 08:59:09 Ahmed Comments on How to Disable Onboard Graphics Card?:
the nvidia control panel doesn't even open if i disabled the Intel graphics card
says that I don't have nvidia hardware connected
544. 2016-09-21 22:36:50 ACMer Comments on Bit Manipulation: How to Set All Bits Between i and j in N equal to M?:
Thanks.. typo fixed.
I see how you got there.
The problem is how to decide the bit at 100. I think it only expands M till the MSB (which should be 1)
545. 2016-09-21 21:34:14 Wenbin Comments on Bit Manipulation: How to Set All Bits Between i and j in N equal to M?:
Probably I misunderstood the description. My understanding is bits from [i, j] would be replaced with value of M.
For example, this case, N=111111 (binary), M=0, i=1, j=2. I think the result should be 57 (111001), but the program gave 61 (111101).
BTW: this line in original article needs to be updated (it should not be i << j):
int left = max - ((i << j) - 1);
546. 2016-09-21 21:16:44 ACMer Comments on Bit Manipulation: How to Set All Bits Between i and j in N equal to M?:
No, it is "int left = max - ((1
547. 2016-09-21 21:04:50 Wenbin Comments on Bit Manipulation: How to Set All Bits Between i and j in N equal to M?:
Shouldn't it be:
int left = max - ((1 << (j + 1)) - 1);

The default compiler that ships with Visual studio 2015 professional.
549. 2016-09-21 08:37:16 ACMer Comments on Fast Integer Log10:
Which compiler are you using?
550. 2016-09-21 08:36:21 ACMer Comments on Fast Integer Log10:
Binary Search is only good for large N, for small N, it is faster without if-checks.
