I 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 am trying to generic way to convert the string datatype to other primitive data type. To achieve, i used Template . But i getting error and couldn't resolve the issue and error reported is also clueless.
in 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)
I have a problem - I have files with rows of data and I need to check if the next row (of the same type) has the NEXT date in it so I need to extract a date in YYYYMMDD format from a row (easy enough) then add one day to it and compare it to the the next date I encounter on a subsequent row.
I'm working with Radiotap headers right now. I want to get the RSSI data. I came through a problem that I can't figure out right now.The value that I need to get is:
Code: s8 IEEE80211_RADIOTAP_DBM_ANTSIGNAL now, when I printf it:
In my system around 73gb(pc-desktop) i have,1 primary partition(windows)-25gb, 1-extended partition(remaining gb) 3 logical partitions were there in (under) extended partition in one of the logical partition is d:drive. in my hard disk d: drive is -/dev/sda5
previosly i was fat -file system , (d:drive-/dev/sda5), i remember i changed the d: drive(d:drive-/dev/sda5) file system to ext4file system ,with following command using terminal
After doing(changing the file system)this one ,i couldnt see the d:drive data
By doing that
1q) Did i reformatted the partition? i think the new filesystem(ext4) has no knowledge of the data that was on it when it had a FAT filesystem.
2q) How to do undo operation,i tried to change the filesystem type to fat/ntfs in terminal using command --sudo mkfs -t FAT /dev/sda5.
Result:its showing text message-'mkfs.FAT: No such file or directory'(not in single quote)
i have Ubuntu10.10 (kernel-2.6.35-22-generic) installed. struct stat StatBuff;
[Code]...
I have mounted a windows share folder on /mnt. When i gave any directory within /mnt/ to stat function it fails with errorno 75. perror shows "Value too large for defined data type". Example 1 is fail but Example 2 works fine.
I am trying to convert a mdf file to iso with mdf2iso and this message pops up "Value too large for defined data type". The file is about 4.6 GB. Any other information
I've downloaded a big file from another server via "wget" to my /backup/ directory, and after the download was compeded I did run "ls" and the error was:ls: full_plesk_backup: Value too large for defined data type.
is there a way to recover data from a hd partition type fat32...cause ...cause right now it shows up as unallocated space..earlier i tried installing windows in a unused partition located just above this partition....i need to recover the data real soon...
i currently have both xubuntu 10.10 32-bit and windows 7 64-bit installed on my laptop which i use mostly for college work and basic programming (i'm still learning to program).i have a 150gb partition with win7 installed, a 20gb partition with xubuntu installed and a 15gb partition with my linux home folder on, the rest of the space is unused because i thought i may need it for something else in the future.the home folder partition is formatted to etc4, i now have a need to access this data from win7 for college work, i know that windows doesn't support mounting of etc file systems so i have hit a problem.
i thought about changing the type of partition from a ect4 to fat32 but will this delete my data? or ,are there any third party software packages for windows that will allow me to mount ect4?
I am using read() in c++ to get data from a serial port. However, if no data is available on the serial port the function blocks until dta arrives.Example code:
I have some data files that should be distributed with my program. Using dist_pkgdata_DATA in Makefile.am, I get these files installed to /usr/local/data/share/package-name. The problem is that data is read-only, and my program needs to modify it. Playing with dist_sharedstate_DATA, dist_localstate_DATA, dist-data_DATA varibles, I got different installation directories, like /usr/local/com, usr/local/var, but data is always read-only.
How can I distribute modifiable data files with my package? I need some common directory for all users, or maybe local data in a user directory.
I make all as mentioned in this guide [URL] and the MediaTomb working with the script but when I try to open .mkv file PS3 says that "The data type is not supported" in same time it shows the files in the menu normally and marked it unsupported thumbnail after I try to play it.
I have included fstream in my file (#include <fstream>) In the file, I have a class declaration and a private variable static fstream fileStopWatch; Then I am getting the error "'fstream' does not name a type" It was working in gcc version 4.1.2 20080704 (Red Hat 4.1.2-48) but not working in gcc version 4.4.4 (GCC)
I 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.
i m doing a program to open a file, however, there is error saying that 'File' undeclared. but I thought File is a type like int or char, isnt it? below is my codes:
I am trying to learn how to use true type fonts in SDL using libsdl-ttf. I am trying to use the font "FreeSans.ttf" but my program prints out the message "Couldn't open FreeSans.ttf." Any way to get a list of what fonts true type fonts exist using C++ and SDL?
ubuntu terminal mingling made me want to learn programming, i started with python, using idle workspace (is this the right term?)i got to the stage when i need and want to use SPE workspace.i have downloaded it, but can't type in it - when i type, nothing happens at all.where have i been wrong please ?
I 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.
