In the first line, DirectX provides this function to store the normals information in ASCII form. Now in the next line, where I altered the original source code, is storing the binary representation of the same normals vector, what I want to accomplish is to store the normal vector as ASCII ....
I'm currently working on a Microsoft (unmanaged) C++ project which utilizes Boost C++ libraries. It's been quite a while since I've done C++ and I have no previous experience using the Boost libraries.
We are using Boost 1.55 and MSVC 2013. We used CMake to generate the Visual Studio solutions and projects based on the original project layout.
We've successfully built and tested on other environments. In the MSVC - Windows environment, we've run into issues using Boost's Property Tree support. Specifically, the issue seem to center around trying to put properties into PTNodes.
This work around seems insert the nodes successfully into the tree.
We are able to verify by finding the inserted items in ::SetResult().
Why this might be failing in VisualStudio C++?
Is this an issue of compiler flags?
precompiler definitions?
Linker options??
Memory mode/model??
Are there some basic behaviour differences in MSVC C++ and other C++ environments which we are unaware of?
I've tried to identify all instances of the node insert pattern and use the work around. But, we really need to find out what the issue is (as there could be other manifestations).
I wonder are there boost available structures that act pretty much the same as binary heaps of C# in VC++?
like this code snippet in C#
Code:
BinaryHeap<Node> OpenList = new BinaryHeap<Node>(); BinaryHeap<Node> ClosedList = new BinaryHeap<Node>();
Code:
namespace LibAStar { /// <summary> /// A binary heap, useful for sorting data and priority queues. /// </summary> /// <typeparam name="T"><![CDATA[IComparable<T> type of item in the heap]]>.</typeparam> public class BinaryHeap<T> : ICollection<T> where T : IComparable<T> { // Constants

i am writing a program that accepts a decimal number from the user and convert it to binary numbers. After the conversion, i should count the number of 1's and 0's in the said binary number. I got upto converting and counting 1's using Brian Kernighan’s Algorithm. But, i can't seem to get it to count the number of 0's.
#include <iostream> #include<bitset> using namespace std; int main() { int num,count=0,Zero,count1 =0; cout<<"Enter the number:"; cin>>num; string binary;
I am very new to programming and have been working on a program that can receive decimals or binary numbers and convert them. The decimal --> binary works fine. For some reason I cannot figure out I cannot get the "BinaryToDecimal" function to perform. By putting a "printf" into the for-loop.
Code:
#include <stdio.h>#include <string.h> #include <math.h> char* ReverseString (char _result[]) { int start, end, length = strlen(_result); char swap; for (start = 0, end = length-1; start < end; start++, end--)
I have a code and am asked to modify it so that it will take as input as unsigned binary number up to 16 digits in length and convert it into its equivalent decimal number and output that decimal number.
All I know is that I use library function strlen() in <cstring> to calculate the length of the input string.
I also know I have to use something called pow(2,4);
//pow (); is found in cmath
I was told to use sum = sum >>16-l; (l is the length of />/>
#include <iostream> using namespace std; int main() {
how to take binary number as an input, generate partial products by bit-wise multiplication and in last step to add all the partial products to generate final products".
using namespace std; void Conversion (int n); int main () {

I now have a follow on exercise that requires me to convert to binary from ant base up to 10, i thought this would just be replacing the 2 with a variable obtained form the user, but i am having problems as within the function i am getting an error that i haven't passed enough arguments and i cant see why i get this. I did the following:
Code: #include <iostream> #include <iomanip> #include <cmath> using namespace std; float Conversion (int n, int b);
The following piece of code is supposed to output the binary representation of a given integer and it does exactly that. However, if the given integer is 2, then output is 01. Is there a way to make the program output 0001. I am working on a C program that outputs 4-bit gray code.
#include <stdio.h> #include <math.h> int main(void) { long int n=2; while (n) { if (n & 1) printf("1");
Write a program to determine the number of binary palindromes in a given range [a;b]. A binary palindrome is a number whose binary representation is reading the same in either forward or reverse direction (leading zeros not accounted for). Example: the decimal number 5 (binary 101) is palindromic.
Basically i need to make a number guessing game where user thinks of a numbver from 1 - 100 and the machine will try to guess it in the least number of times. Once it guesses the number it will also say how many tries it took to guess.
My code so far is
#include<iostream> using namespace std; const int MAX = 100; int main() { char ch;
cout << "Think of an integer number between 0 and " << MAX<<endl; cout << "Write it down on a piece of paper then hit a key to continue"<<endl<<endl; cin.get(ch);
If I have a number 117, represented in binary as : 01110101 and I wanted to grab the top nibble. What would be the decimal value I would be extracting?
Would it be 0111 or 0101 decimal values 112 or 5 or is my understanding completely wrong?
I have a problem to read a large number of binary files, process them and store them under a new name. The program and routines go very well for 505 files. After reading 506 files, the program now refuses to read the next file. I have 16 Gb of memory and tried to close all other programs and restart the PC. it always stops after 506 files (512 files would be more understanding in a way...).
Here is my code. I have tried many things without success. This is only part of the loop that stops. The if test if (myfile.is_open() returns false by some reason. I can start the process again starting with the file that does not open and then it stops again after 506 files.
char * tfiBlock; ifstream myfile (OrigFilename, ios::in|ios::binary|ios::ate); if (myfile.is_open()) { int lengde = myfile.tellg(); tfiBlock = new char [lengde]; //static char memblock [size];
[Code] .....
Clean up procedure: delete[] tfiBlock;
Are there any limits to how many files that can be opened, or is it maybe someting to be set in the compiler?
My size of binary file is 1920 KB and my struct size is 124 kb. now to find number of records in file I divided 1920/124 and it gives me 15.4.... do I add 1 to 15.4 and make it 16 or do i take it as 15?
My assignment is "Search Benchmarks: Write a program that has a sorted array of at least 20 integers. It should call a function that uses the linear search algorithm to locate one of the values. The function should keep a count of the number of comparisons it makes until it finds the value. The program then should call a function that uses the binary search algorithm to locate the same value. It should also keep count of the number of comparisons it makes. Display these values on the screen."
I'm unsure how to make it show the number of comparisons it takes to find the value for the binarySearch function. Also, where to put the selectionSort function the teacher said we need. This is what I have...
#include <iostream> using namespace std; int linearSearch(const int a[], int num); int binarySearch(const int a[], int num); void selectionSort(int a[]);
i'm trying to use binary search to find a number in the array but i dont know whats wrong with my code. When l enter a number which DOES exist in the array, everything is ok... but when i enter a number which does NOT exist in the array, i have problem...i cant exit the program, it just continues to run.Here is my code
