Programming :: Checking For Alphabets ?

Jan 25, 2010


I am trying to do a search to check if the input is using alphabets and nothing else.

I tried using [[:digit:]] and [[:alpha:]] but none seems to work

When i use digit, it read 22.k as alphabet and not as a wrong syntax.

For alpha , it does not allow me to input data which has spaces such as " hello world".

Programming :: Data Validation - Input Contains Digits And Certain Alphabets

Apr 8, 2010

I 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...

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?

OpenSUSE :: Firefox Font - Gaps In Alphabets Are Making Them Difficult To Read

Jul 9, 2010

I am facing some problems in font rendering issue for Urdu (South Asian language). Actually the alphabets are being displayed as, for example, "a p p l e" instead of "apple" - if you see this website, probably you will see the gaps in alphabets are making them difficult to read.

I have installed at least 10 different Urdu fonts but still no help, then I tried adding:

MOZ_DISABLE_PANGO="0" to /etc/environment but it also did not helped.

I am using OpenSuse 11.2, Firefox 3.5.10

But, is there any possibility to check without our login?(not even by ssh)

Programming :: Certain Book Search - Checking Of Case Insensitive

Jan 19, 2010

I am trying to do a search for the certain books, and I am trying to make it case insensitive. what I have come up with so far is this :


echo -n "Title: "
read Title
echo -n "Author:"
read Author
echo ""
valuecheck='grep -i "$Title" Database.txt | grep -i "$Author" | awk -F":" '{ print $1}''
echo $valuecheck
if [ $Title = $valuecheck ] ; then
echo "HOHOHO"
echo "too bad"

The issue which I am having is that, when it does the search for the correct row to be inputted into valuecheck, it will input the value as written in the database, which is in Uppercase. For this case, if I type in stupid for $Title and jerlyn for $Author, it searches the correct row, but the awk will print "STUPID" into the variable as that is what is written in the database. So how can I make my if statement case insensitive? Currently it reads like this:

if [ $Title = $valuecheck ] ; then
which means
if [stupid = StUPiD ] ; then

How can I make the if statement it case insensitive to allow it to display "HOHOHO"

Programming :: Checking Pattern But Ignoring Multiple Space?

Apr 8, 2010

i am searching a string(with multiple words) in a file that file contains the string but words are separated with multiple white space.

ex: pattern to be matched "hello how are you" all single white space and file contains " hello how are you" variable white space between words

grep "pattern" file_in_which_to_search i am reading the "pattern" so i cannot modify the "pattern"

so my pattern match does not take place, though i want it to match.

Programming :: Checking Shell Script Variable Contain Numeric Data

Mar 28, 2009

I need to check whether a shell script variable contains non-zero numeric data to proceed. The variable should contain numeric values, but may in fact contain zeroes, blank space or nothing. So far, I have tried various combinations of:

if test $variable
if test $variable -gt 0
echo "good data exists"
else "no good data exists"
It partially works, but I get either "too many arguments" or "integer expression expected".

For example German spell checking: The command :mkspell ~/.vim/spell/de /usr/share/hunspell/de_DE.aff generates a de.utf-8.spl in the right folder, but vim marks every word as wrong when I activate it with

Fedora :: Bad HDD Stop Kernel From Checking It

Aug 24, 2009

I will keep this short, I have a bad HDD possibly PCB damage due to heat.It's a laptop although I can remove it but in the mean time till then, is there any way I can pass an option to the kernel to stop scanning it.My OS mounted on a 8 gb sd card plus 4 gb flash drive.It takes 20 minutes for Fedora to bootup and Debian base Linux 30 to 35 minutes.

It wouldn't been a problem setting my laptop to sleep mode when I'm done and it was working fine but after a few updates, once I put my laptop to sleep I can't do it again in the same row. I have to shutdown. Lets say I tried anyway, system stop being responsive, while I let it continue to see it will become responsive again, it went on for an hour and half. It's annoying... So my question is, what option can tell the kernel to not scan my HDD.

Fedora :: Checking If OpenGL Is Working?

May 31, 2010

I'm trying to get a program to compile with OpenGL support and it's saying that the headers are missing. But I think (or thought!) that I already had Open GL up and running. My suspicion is that I need to install the appropriate -devel files...but I just can't seem to find them. Furthermore, I don't want to tweak my system and install proprietary Nvidia drivers if things are already working just fine.

I have a Geforce 8300 GS in a i586 32bit Dell Inspiron 530. I'm trying to compile Cinelarra and keep getting:


OpenGL 2.0 libraries missing Hardware acceleration using OpenGL 2.0 is disabled

Does anyone know which driver (ie: 96xx? 173xx?) I should be using for this? Where are these libraries? How can I find them and tell Cinelarra where to look?

And even more basically: How do I tell if OpenGL is working or not? Maybe I don't have them afterall..

Fedora Installation :: Checking For Libraries Currently In Use?

Jul 19, 2010

I have just installed from the Live Cd (Fedora 13). So far so good except that I have just installed the updates (which has taken some time) .

The updater screen shows a full progress bar and next to the progress bar is this text " checking for libraries currently in use" this has been at least one hour showing the same thing, it hasn't changed (PC is still running OK). Does this mean I can safely quit and the updates will be OK or should I keep waiting for a reboot screen or updates success message ? Is this normal, if so how long does it usually take to complete?
