Server :: MySQL - Add An ENUM Value Later?
May 8, 2011I create a MySQL table with a ENUM column with the possible values BOOK, DVD, and CASSETTE. And then two years later I decide I want to add another possible value (say, ISOLINEAR CHIP :-). This won't be a problem, right? I got the impression from an on-line post that I could use ALTER TABLE to do this and it wouldn't be a problem. But I wanted to get a second opinion because obviously I don't want to come back two years later and run into some major issue.

General :: Data Type In Programming?
Jun 14, 2010I declared a variable as int data type which was a placeholder for a resulttatus (meaning, based on the result status that variable varies from 0/1/2/3. It can contain only these four values).data type is 4 byte integer in C#. But I can declare this variable as which represents a 1 byte integer. Since that variable contains only 1 or 2 or 3 or 4, declaring the variable asis wastage of memory space.Before declaring any variable we need to just think of the memory space needed for that variable, our requirement,

I think I'm doing it wrong, cause these objects have different sizes, so I don't know if I could have all of them in a single array.
Programming :: Get List Of Variables Of Particular Type ?
Jun 13, 2011I have a C header file which have arrays of predefined(known) structure type. But i dont have names of arrays and their size. when i include that file and compile my application, i want to know the names and sizesof those arrays.
purpose of application is to get the content of those arrays and to explain it in descriptive words instead of hex numbers.ofcourse this can be done by file pointers and reading also with out header file inclusion, but as i am working in C, once compiled, those variables are in my address space in i include header file.

View 3 Replies View RelatedProgramming :: Double Data Type Mantissa?
Nov 23, 2010in c/c++, double is usually 8 bytes. It has a 52-bit mantissa (or significand, or base), an 11-bit exponent, and a 1-bit sign. My question is: is the mantissa a 52-bit integer? Or is the decimal point just after the first bit. Meaning: if the mantissa was 1000110011100011 (in binary) would that make the value of the mantissa (assuming the exponent was 0) 1000110011100011, or 1.000110011100011? (in binary)
View 1 Replies View RelatedProgramming :: Child Classes That Extend Each Type Of Pet
Jan 6, 2011I am fairly new to c++. There must be a better way to do the following?:- Say I have a base class, Pet. I have several child classes that extend from this, like Dog, Cat, Fish etc.
I have the following function, that returns a pointer to a new Pet:-
Code: Pet* addPetToVet()
{ //Do some stuff
return new Pet();
} This will return a pointer an instance of a pet object.
Now, if I want to interpret this pet as a dog or cat I have to do this:-
Code: Dog* dogA = static_cast<Dog*>(addPetToVet());
Cat* catA = static_cast<Cat*>(addPetToVet()); Is there a way around this? Casting seems lame. I cant write a function for each type of pet.

May 25, 2010I'm sure this has been covered somewhere before, but I couldn't find anything and so figured I would post here. I have been using Linux OSes for the past couple of years and also using GCC/G++ for application development. However, I have almost always been on x86 systems and never gained much experience using the wide range of optimization options available.
My question is, if I do not specify the -march=PROCTYPE option, will GCC still be able to detect the current architecture and build the code accordingly? I primarily ask this because I am working with an x86_64 system, and specifying -march=x86_64 in my makefiles generates errors about it being an unknown processor type, even though the CPU and OS are X86_64. I know this sounds like a newbie question, but it's just ground I've never had to cover before until now.
Programming :: Get Program Based On Mime-type In C
Feb 10, 2010I need to launch programs in my program and the program can be a script, a Linux executable or even a Windows executable. The first thing i tried is to use xdg-open from my program, but i can't pass arguments to it, otherwise it would have worked perfectly. Is there maybe a way to determine which program is set as default according to the mime-type of the program i want to launch? I also tried kfmclient and gnome-open, they don't allow arguments either.

Jan 27, 2010I'm a n00b to both numpy and python. I was wondering what the most intelligent way to write the trapezoid rule function was:
Code:
>>> import numpy as np
>>> a=np.array([1,2,3,4,5])
>>> def mytrapz(vec):
total=0
for i in xrange(0,len(vec)-1):
total+=(vec[i]+vec[i+1])/2.0
return total
>>> mytrapz(a)12.0 This is exactly what I would do in C and I'm sure the for loop is not the fastest way (as is the case for my interpreted langs). Yes, I know there is already numpy.mytrapz... I'm interested in the most efficient way to loop over arrays in such a way that each iteration accesses more than one cell.

Programming :: DB2 VARCHAR Type Usage With NULL Character?
Mar 7, 2011I have a vector of bytes that I need to store in a DB2 database and was wanting to do it with a column declared as VARCHAR () FOR BIT DATA. I can do this with no problem except when a byte representing the NULL character occurs in the vector. Anytime this occurs, the rest of the bytes are truncated. I know this is the proper behavior for if this were a string, but I was under the impression that if the column is declared as I previously mentioned, that this would support any variable length binary data including the NULL character.
I've found repeated references to people dealing with DB2 tables where the data in VARCHAR columns contained leading and embedded NULLS, so I know this is possible. Can anyone provide me with the proper INSERT statement in order to get this to work? This is the current BindParameters call I'm making for the VARCHAR () FOR BIT DATA column that's truncating after the NULL character occurs.
Code:
SQLBindParameter(handleStmt, 3, SQL_PARAM_INPUT, SQL_C_CHAR,
SQL_VARCHAR, (SQLUINTEGER)(30000), 0, data2, 30000,
