I have a struct (small instance so not using code brackets )
struct random { int a; int b; }example;
What i am trying is
example={0,0};
and it gives an error how to initialize all the entries within a struct to zero? In the above example i have used integers but what if they are some other data structure for example another structure?
I am using semaphore.h I declared a variable of type sem_t. I am able to use the variable without even calling sem_init or sem_open, and it is working properly.if the variable is automatically assigned some value? Also would I run into any trouble doing so?
I'm making script for automated compiling of one program which would output builds optimized for many architectures. For clearancy, I do each build in it's own catalogue and list of builds with their respective catalogues would be stored as array. I'm using this guide as reference. It describes making array as naming a variable with additional brackets denoting it's position in array.
I'm trying to read content of file to variable and use this variable in for loop. The problem is, when I have c++ comment style in file - /*. Spaces in line are also interpreted as separated lines.
For example:
Code:
Changing $files to "$files" eliminate these problems but causes that whole content of variable is treated as one string (one execution of loop).
my script has a variable which comes in the form +00.00 +0.00 -00.00 or -0.00 (the numbers can be any in that form) for any that have a + symbol I need to remove the +, but if it has a - symbol it needs to stay.
i need to make a new variable with the string from the old variable btut without any plus sign. I have tried a lot of different ways with no success, each thing I tried either left the + or removed the entire string. I think this should work but doesn't
The code below defines an array of structures in a class. I would like this to be a Static array and then initialize the array in a initialization method. I understand that initialization lists are the way to go but due to the size and complexity of the array I plan on using (the example below is a simple snippet that illustrates the problem) I would like to use the initialization method. However, I cant even get this thing to compile. The error says the reference to the ArrayOfStructs in the initialization routine is undefined.

P.S. This is the error message
undefined reference to `ClassWithStaticArray::ArrayOfStruts'

Kernel 2.6.21.5, slackware 12.0 as 2.17 [I am speaking here about 80x86 processors, with their segment registers SS, DS, CS, ES.] In a source file for as, I wrote
Code:
.section _STACK .rept 4096 .word 0 .endr
Now, in the .text section, I want to initialize SS, the stack segment, to point to the _STACK section. In other assemblers, there was a special section for the stack, and the linker cared about initializing SS. Here I use a common section for the stack. For a segment such as DS, I could write
mov ax,_DATA mov ds,ax
But I don't think mov ax,_STACK would do with as/ls.how do I initialize SS?
I need to replace JAVA_OPTS= with JAVA_OPTS=<some_value>.I need to give "" value at the end of the replacement. I have tried with the following but it is not working: sed -e "s|JAVA_OPTS= |JAVA_OPTS=<some_value>"
how shall I print each variable separately using a generalized form. I tried writing the following within a for loop...Code:echo $(echo a$(echo $i)$(echo $j))which did yield no result. So what shall I write??
Event 1............................................................ full_name: JENNY_JENNINGS genre: f age: 32
[code]....
But as you can see in the input, in the 2nd "Event", the line containing "age" is not present, but in the output my code is printing the 1rst age value twice. The correct output should be blank in the age field for 2nd line in the output like this:
i'm trying to execute a shell script, i'm trying to use the values in an array for use in a sed command:
sed -n '/Sales ID: ${array[$i]}/,/Totals:/p'
that command creates empty files. so my guess is that its not recognizing the array as an array but as text? how would i be able to utilize the array in the command? i got it, didnt think that if i doubled up the single quotes that it would work, but this worked:
It compiles fine, but gets stuck in the loop. z never increments. I was using a for loop originally but had the same problem so I decided to try a while loop.
