How can I allocate enough memory to store an entire text file in C?

fixed the issue. Will look into that further You seek to the end to get the file size but don't seek back to the beginning before your read. Add this line after the ftell call.
code :
fseek(logData_fp, 0, SEEK_SET);

To fix the issue you can do sed -i -e '1d' file will do what you want.
-i indicates "in-place" -e means "evaluate this expression" '1d' means, delete the first line

PowerShell: Store Entire Text File Contents in Variable

it should still fix some issue I'd like to use PowerShell to store the entire contents of a text file (including the trailing blank line that may or may not exist) in a variable. I'd also like to know the total number of lines in the text file. What's the most efficient way to do this? , To get the entire contents of a file:
code :
$content = [IO.File]::ReadAllText(".\test.txt")
([IO.File]::ReadAllLines(".\test.txt")).length
(gc .\test.ps1).length
[io.file]::ReadAllText(".\desktop\git-python\test.ps1").split("`n").count

Read entire XML file and store in memory java

this will help The easiest way to do this would be with JAXB. You can use xjc to generate Java classes from your XML schema. Then use JAXB to unmarhsal (load) your data, manipulate the Java object just as you normally would any other object (using getters/setters), and marshal (save) it back to an XML file.
You could also use DOM directly, but manipulating the DOM is a lot more tedious than working with POJOs that directly mirror your XML structure.

how to allocate memory to store register number?

I hope this helps . If there is only one possible value, you need no bits at all. If you have one bit, it has two possible values.
So if there was only one register, no bits would be needed at all to select it. If there were two registers, you'd need one bit -- a zero in that bit could select one register, a one the other.

operator 'new' to allocate memory to store pointers

like below fixes the issue This is really stupid question to ask but I really didn't find its answer anywhere else. I am just trying to allocate memory to store pointers. It should be most easy. But annoyingly its not working (In VS2010 on Windows)... , The compiler error with gcc:
code :
$ g++ test.cc
test.cc: In function 'int main()':
test.cc:3:23: error: array bound forbidden after parenthesized type-id
test.cc:3:23: note: try removing the parentheses around the type-id
intptrs = new int*[10];
#include <vector>
int main() {
  // create 10 pointers to int
  std::vector<int*> intptrs(10);
}
