C++ :: Running Unit Test On Library - Checking For NAN?
Jan 31, 2012I am running a unit test on a library and this line keeps failing on Fedora 16, G++ 4.6.2
Code:
assertNAN(double, std::numeric_limits<double>::signaling_NaN()); //sanity check
The assert looks like this
Code:
//needs to copy it so that if its a function call it only does it once
#define assertNAN(type, one) {
type val = (type)one;
std::string lag(#one);
lag += " not a number";
[Code] ...
I am compiling with -DNDEBUG -O3 -ffast-math -fexpensive-optimizations to simulate a production environment. Is there a way to test for NAN consistently?

Visual C++ :: Running GUI Program In Background?
Apr 22, 2013i created a windows service that will run another program. but the program i want to run has a gui and i don't want the gui to be visible, i just want the program to run in the background.
But i have to do it without editing the gui program
here's my code:
Code:
TCHAR* path = L"C:Myfile est.exe";
STARTUPINFO info = {0};

C++ :: Dynamically Resizing Array While Program Is Running?
Feb 4, 2015 I'm working the 4th problem in chapter 14 of the Jumping into C++ book. In the book, he gives an example program for dynamically resizing an array while the program is running. It works fine for integer types but i need to do the same with a string type array. Right now my program is crashing because the string array is not resizing itself. Here's the part of the code im trying to figure out. The part for the int array has been ignored using // since it works fine and I'm trying to figure out whats wrong with the string array.
Code:
#include <iostream>
#include <string>
//Write a program that lets users keep track of the last time they talked to each of their friends.
//Users should be able to add new friends (as many as they want!) and store the number of days ago

C :: Simple File And String Program Not Running
Mar 6, 2015The assignment is to write a program that statistically computes similarity of C syntax with another program; a same and a different. The one used here is in C language, it's called Battleship.cpp. The program must open a file and read line by line for keywords and then produce statistics. The reason my code is not running is the fopen function is failing and it goes to return -1. I am using MS Visual Studio 2013 and there are no compiler errors after turning off deprecation. I do see, however, this error UMEngx86.dll'. Cannot find or open the PDB file. The file being opened is in my source folder.

C :: Bit Checking - Stack Overflow
Sep 19, 2013I usually check if a bit is set using:
Code: bit = (number >> n) & 1; where `n` is the bit I want to check...
But I came across a stackoverflow answer saying:
bit = number & (1 << x); will not put the value of bit x into bit unless bit has type _Bool (<stdbool.h>).
Otherwise, bit = !!(number & (1 << x)); will..
So why is this? why the double !?

C++ :: Checking For 3D Primitive Collisions
Aug 4, 2013I think I may have found a new way of checking for 3d polygon collisions, but I'm not sure. The method involves...
1. finding the planes that the primitives lie on
2. finding the line where the planes intersect
3. if both polys have points on both sides of the line AND have points that overlap on the 1d space of the line, then they intersect.
I have some half done code testing this, and so far it seems to be sound and fairly fast. These are some average time-tests done on my machine for each part:
1. 30 microseconds (both)
2. 7 microseconds
3. TBD
C++ :: Checking For Deallocated Memory?
Jul 20, 2014How would I go about checking for deallocated memory?
For example, let's take this into consideration:
// Unsigned 32-bit / 64-bit integer: uint32, uint64
uint32* Pointer = new uint32[ Size ];
uint64 MemAddr = ( uint64 ) Pointer;
delete[] Pointer;
The above code would proceed to create a new array, store it in a pointer and retrieve the memory address of the array before finally deleting the array.
So let's assume we re-build the pointer and try to access the now deallocated array:
Pointer = ( uint32* ) MemAddr;
Pointer[ 0 ] = 0;
Based on the above snippets of code, how would I check "Pointer" after rebuilding the memory to check if the rebuilt memory has actually been deallocated. Without a check we'd get an exception error.
A bit of detail on why I am trying this:
Before thinking up how to do this, I was storing the addresses in a list and check the list for the addresses to see if they existed or not. However this requires an O(n) search, which isn't exactly what I am wanting. So instead if I used a check for deallocation method, I can go for an O(1) time check and reduce the total time it would take to check for memory allocation/deallocation.
