Programming :: Getting Number Of Digits In Uint64_t?
Jul 7, 2011I'm having a hard time trying to get the number of digits in a uint64_t variable. The reason I'm using this is I want to make sure I get x amount of digits inside of a variable before I use it, but since the higher the digits, the better the program is.I currently use the following code, and it works, but my loop will never exit because the length is always 0:
Code:
/**
* numbdigits()
* number: The number to evaluate [in]
*
* Returns the number of digits found in a number.
[code]....
getrand() returns a uint64_t as well (and works). The only way the while() loop ends without my intervention is if I do curd += numdigits(val) instead...but, that gives a false value as well.

Programming :: Data Validation - Input Contains Digits And Certain Alphabets
Apr 8, 2010I am having a huge problem checking the data I input to make sure it is correct. What I am trying to achieve is when I input a value, it will check if the input is all digits and if it is not, check to see if it contains certain alphabets. Thus for example, if I were to input in data such as "11A" , the program will then inform me "There is an important alphabet in the program." This would be my expected output. Here is the program I have wrote...
Code:
int test(string r ){ const int arraySize = 10;
char array2[arraySize2] ={'A','B','E','F','G','H','J','K','N','O','P','Q','R','S','T','U','W','Y','Z'};
for(int cntr = 0; cntr <r.length(); cntr++)
if(!isdigit(r[cntr])){ for(int new1 =0; new1<arraySize2;new1++)
for(int cntr1 = 0; cntr1 <r.length(); cntr1++)
if(array2[new1] == r[cntr1]){ return 2; //will return2 when it finds the same
// char in the array and the string r. } else{ return 3;
//will return 3 when there is a char
//in the string which isnt in the array
} } else { return 1; // will return 1 when string is all digit.
} int main() { string r = "11D"; test(r);
if(test(r) == 1) { cout << "ALL ARE DIGITS" << endl;
} if (test(r)== 2) {
cout << "There is an important alphabet in the program." << endl;
} if (test(r)== 3) { // testRoman(r);
cout << "There is an Alphabet in the String which is not in the Array" << endl;
} }
So, the problem I am facing is when I input in data such as 11 or A , the prog will come out the right input. But if I were to put in data such as "11A" , the output coming out will be "ALL ARE DIGITS". The problem which causes this seems to be in the return statement , as once as it finds the first char which is a digit, it will then return 1 and not continue checking the rest of the string. Is there a way I can stop or continue a loop if it has met the condition I stated? What I can do or any other way available for me to check my input?
Programming :: Rename Files Recursively, Only Keeping Last X Digits Plus Extension?
Nov 29, 2009My problem is this:I have a number of directories, all containing files of different name lenghts, including letters, numbers and possibly spaces. I want to recursively rename all of these files, so that only the _last_ 5 digits (not counting the extension) remain. In other words: I want to cut off all but the last 5 digits and not touch the extension.
I've tried to read up on tr, rename (perl version), sed, cut etc. and browsed through some threads here, but so far couldn't quite figure out how to do it.
If someone could point me to the right (standard) CLI tools and syntax.

Jul 5, 2011I was wondering what is the maximum number of partition on an GPT-partitionned drive under Linux. The GPT partition table can contain up to 128 partitions, but the device nodes for /dev/sda? (as described here, block device of major number 8) only allow /dev/sda1 up to /dev/sda15. Does that means that there cannot be more that 15 partitions on a drive, even on a GPT-partitionned drive?

Debian :: Laptop Brightness Gets Set To Maximum On Boot
Jun 10, 2010My laptop brightness gets set to maximium each boot.
Just wondering if this is the case for other laptop users. I have a Lenovo Thinkpad SL500 (GeForce 9300M GS) and am running Testing.
Ideally I'd like it to remember my last setting (which is usually the lowest). It'd be nice not having to turn it down each time I reboot/power-on.
It actually starts off at a low setting but during the boot process (before gdm and just after the "Waiting for /dev" line I believe) it suddenly gets set to max.
Debian Hardware :: CPU Frequency Always Maximum After Boot
Aug 1, 2014I have both cpufrequtils and acpi-whatevercpu, normally processor would be correctly controlled by the ondemand governor and have two steps for frequency, 1.4 and 3.5GHz. Now I've noticed my frequency is always at 3.5GHz, cpufreq-info gives me the hint:
Code: Select allguiu@guiu-desktop:~$ cpufreq-info --cpu 0
cpufrequtils 008: cpufreq-info (C) Dominik Brodowski 2004-2009
Report errors and bugs to cpufreq@vger.kernel.org.
[Code].....
This isn't really a big issue. Normally the processor will sit at +-28°C at low load levels at maximum frequency, with the proper governor it will drop to +-20°C (room temperature) and lower. So I still would like to get proper management of frequencies for more hardware life, and better energy efficiency, not to mention quieter fans. Documentations on cpufrequtils is very broad, and apart from that I don't know where to look for this. Debian wiki page mentions about a file that can be used to configure this but there isn't much documentation.
Ps: I previously had this issue where acpi-cpufreq driver wouldn't load at all, this is due to setting on bios resulting in different frequencies than stock, trying to get default frequencies allowed the driver to work.
Debian Hardware :: Can't Display Maximum Resolution
Jun 29, 2010I have a brand new computer with an ATI Radeon HD5850 video card I have a LCD monitor with a native resolution of 1920x1080. I installed Debian Testing 2.6.32-5-amd64
Because I have several machine, I use a KVM (switch keyboard) in the middle. This KVM is quite old but still work correctly only problem is that it don't forward the EDID information. Until now it wasn't a problem, and by specifying the correct parameters of the monitor in /etc/X11/xorg.conf , I always succeed to reach the 1920x1080 resolution
In installed the proprietary drivers from ATI Catalyst 10.6 (last version)
since I have 2 problems :
first in the console I used framebuffer in 1280x1024x32. Before installation of the ATI drivers, it was ok, now the screen is completely black !! on every tty (I didn't investigate much on this trouble yet)
Second problem:
I can't reach the native resolution of my monitor ! No matter what I'm doing, the best the driver propose is 1600x1200 !!
I made a lot of test and modification in xorg.conf but without success, it always goes back to this resolution and never propose something higher For information, if I connect the monitor directly to the video card (removing the KVM), everything is OK and the resolution is automatically set to 1920x1080
/etc/X11/xorg.conf

Identifier "aticonfig Layout"

Fedora :: Maximum Number Of Files In Ext3 ?
May 26, 2010Is there a limit to the number of files ext3 can support?
Reason I'm asking is because on one of my internal drives, I have around 750,000 files. The drive is 500Gb and currently using 150Gb... I noticed recently that when I try to copy a new directory or file, the transfer rate is extremely slow at times. It is sataII and sometimes it gets as low as 500kb/s (yes, kb!)
Would somebody please shed some light?
I noticed it might be related to the process gvfsd-metadata
I'm using Fedora 12 64-bit
The transfer is from an ext3 to ext3 filesystem.
