Ubuntu :: Field 'struct' Has Incomplete Type

May 13, 2011

I'm building a symbol table and syntax tree using lex and yacc for a compiler.

I am stuck with an error for too long. I have defined two structures (one for Symbol Table and another for Syntax Tree).

Code:
typedef struct symbolTable{
char name[30];
.....
struct symbolTable *next;

[Code]......

here's the error:

bottomup.y:76: error: field 'info' has incomplete type.

I tried to define the structure definitions in a separate header file and included in .y file but it didn't work out.

I'm trying to get this done ASAP.

Ubuntu :: Error: Can't Perform Indexing Operations For <unknown Type> Type

I just loaded octave. I ran through a few examples of how to implement a script file. Everything works until I get to "plot". When I run the "plot" command I get the following.

octave:2> test1.m

Just to double check my work, I ran the following code:
y=[1 2 3];

Programming :: Converting C Code To C++ Causes An Type Error?

Mar 25, 2010

I'm a C / assembler programmer so am not use to C++, which I need to use. Basically I'm using my own versions of memcpy, but for long and int rather than char. It's for fast graphics. So I have a char array which I copy to another array. But I copy as either longs or ints, much faster. for example

Code:
void * fastmemcpysprite (void *destaddr, void const *srcaddr, size_t len)

Programming :: Perl's Foreach Loop Can't Use An Array Element As The Control Variable?

Jul 22, 2011

I'm reading "OReilly Learning Perl 5th Edition", and there are such words:Code:You can use an array element like $fred[2] in every place? where you could use any other scalavariable like $fred.At the bottom of the page, it explains the ? like this:Code:The most notable exception is that the control variable of a foreach loop, which you?ll see later in this chapter, must be a simple scalar.Since Perl has the save-and-restore mechanism for the control variable, why an array element can't be used as the control variable

Ubuntu :: Changing File System Type To Another Filesystem Type - Does It Effect On Data?

Feb 4, 2011

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

Programming :: POSIX__Philosophers At Dinner: Error: Initializer Element Is Not Constant

Jun 23, 2010

I changed my post because I found that solution, and didn't want to bother for that. But, since I didnt find a way to delete the post, I thought of updating it: I am beginning to write the code for the philosophers problem. As you know, they can eat, think or wait for forks. When they have 2 forks, one by each side, they eat. Then they set the 2 forks as available, and think.

Each philosopher is a thread. My problem is that it gives segmentation fault, somehow, when I try to initialize. The thing I really don't understand, is why it sometimes gives segmentation fault on initialization #0!!! (But generally on initialization #1) I have set 5 initializations in total, defined by N, that is also the number of threads I'm working on.

PHP Code: #include<stdio.h>
#include<stdlib.h>
#include<unistd.h>
#include<pthread.h>
#include<errno.h>
#include <time.h>
#define N 5

General :: Data Type In Programming?

Jun 14, 2010

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,

Programming :: Dynamic List With Different Type - C++

I wanna to create a list to store my objects. I'll resume them here:

And what I want to do is an event list:

Sometimes this works and sometimes I got "segmentation fault".

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, 2011

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.

Programming :: Double Data Type Mantissa?

Nov 23, 2010

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)
