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.

how to convert a dictionary data-type to a string?
actually I am trying to update some json file 's dictionary.
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 had very imp data in d:drive
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,
View 6 Replies View Relatedin 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 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 going to write a function which will do different operation base on the data type of the input parameter.
I am using C (Pure C, not C++).
The problem is that I do not know how to get the data type of the input parameter in C Language.
Can anyone tell me how to do this.

View 2 Replies View RelatedI have this JSON encoded data, which I want to efficiently parse (i.e. fast, with minimal system resources). I don't want to use a/the shell any more than necessary.
Here's a snippet of what the raw serial data looks like:
Code:

So that's fine. I currently have at least two ways of parsing it:
This Perl method (which I don't much care for because I'm not much into Perl, and because the output is not much more useful than the raw form, and imho even more cryptic):

# Which means: at x=1680, draw a 20x20px grey block, then back up -10px and draw a "1" on the block.I figure that the two awk's I've used can be combined into one -- but I began having problems with removing the single quotes if I did it within the awk, which is why I stuck a `tr` in the middle.
I know this sucks. So, if someone has some ideas or thoughts on something else to do with this JSON data, that's less convoluted that where I'm currently going, I'll be happy to hear about it.
PS - I know this whole post is possibly hard to understand -- if you need more info (you mean you're interested in this mess?? )
