C++ :: Count Number Of 0 In Binary Number
Apr 11, 2013i 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.

C :: Binary Number To Decimal
Mar 30, 2014I 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--)

C/C++ :: Binary Number Into Decimal?
Sep 10, 2014I 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 />/>

C/C++ :: Program To Print Out Binary Value Of 16 Bit Number
Sep 22, 2013Write a program to print out the binary value of a 16 bit number.
Create integers i, count, and mask.
Set 'i' to a hex value of 0x1b53.
Set mask to a value of 0x8000. Why?
print a line to show the hex value of i and then the leader for the binary value like this: Hex value = 1b53 Binary=
Use a for loop to loop 16 times and print 16 digits, using count as the loop counter
To test for each digit value, bitwise and 'i' with 'mask'
when the result for the bitwise and is true, print the number '1'
when the result for the bitwise and is false, print the number '0'
then shift mask one place to the right
print a new line and then quit
Use prtscrn and make a hard copy of the code with the console output.
Extra: use the modulus of count and print a space after every 4th digit to make the binary easier to read
The output should look like this: Hex value = 1b53, Binary= 0001 1011 0101 0011
so far this is what i have
#include <stdio.h>
#include <stdlib.h>
int main() {
int i, count, mask;
// 1B53 0001 1011 0101 0011
// 8000 1000 0000 0000 0000
i = 0x1b53;
[Code] ....
it is telling me that there is an "else" without previous "if", also is the program that I wrote correct?
C :: Determine Number Of Binary Palindromes In Given Range?
Oct 26, 2013Write 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.

C++ :: Reading Large Number Of Binary Files
Apr 14, 2014Windows 7, 64 bits, Visual Studio 10.
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?
C++ :: Array Of Hex Numbers Representing A Binary Number
Sep 24, 2013So basically I have an array of hex numbers representing a binary number. Each binary number is 1/5th layer of the over all font.
For example... the letter A
........ B00000000 0x00
.****... B01111000 0x78
...*.*.. B00010100 0x14
...*..*. B00010010 0x12
...*.*.. B00010100 0x14
.****... B01111000 0x78
........ B00000000 0x00
As you can see each HEX number is a layer in the font which consists of in the above example 7 layers.
Now what I would like to do is create a C++ program, so I can visualize a HEX font array that I got off the internet.
#include <iostream>
using namespace std;
const char font[][5] = {
{0x00,0x00,0x00,0x00,0x00}, // 0x20 32
{0x00,0x00,0x6f,0x00,0x00}, // ! 0x21 33
{0x00,0x07,0x00,0x07,0x00}, // " 0x22 34
{0x14,0x7f,0x14,0x7f,0x14}, // # 0x23 35
[Code]...
Basically I am asking two things. How can I make this display the correct representing letter in the array when a user inputs his own text.
And secondly, how can I output the HEX numbers that is in the array as a binary number.

Apr 23, 2015My 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."

C++ :: Serializing Binary Number With Boost Ptree

std::vector<char> normals;
//stored->AddDataObject(TID_D3DRMMeshNormals, ("normals"), 0, normals.size(), &normals[0], &sNormals);
ptree& sNormals = stored.add("normals", &normals[0]);
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 ....

<y>0.5</y>
<z>0.5</z>
</normals>
How can I achieve that with boost?
C++ :: Binary Search Algorithm - Find Sum Of Used Number In Sequence
Mar 27, 2014I have to made a programme which will search for given number and it must work in O(log(n)). The problem is that this programme beside finding this number have to find how many times this given number is used in this sequence.
Sequence is from lowest to highest only one possibility to use binary search algorithm
For example when we have squence
-1 -2 3 3 3 3 4 5 6 7 7 8 9 9 9 9 10
The numbers we need to search are
1 , 3 , 7 , 9 , 11 , 12
The answer is
0 , 4 , 2 , 4 , 0 , 0
So we need to find the sum of used number in sequence.
I have written algorithm Code: int start = 0;
int end = sequencelenght - 1;
int mid = 0;
/// Binary serach
while (start<=end) {
int mid=(start+end)/2;
if (sequence[mid]==givennumber) {
[Code] .....
As u see i search for given numer with binary with O(log(n)) but when i have to sum the duplicates the only good way i see is using loop to right and left but this have got log(n) specification (because when sequence would be for example 7 7 7 7 7 7 7 7 7 and given number to search will be 7 this will be O(n) loop).
How would look the most optimal algorithm look for this exercise? I mean O(log(n)) the fastest algorithm....
C :: Convert Decimal Number To Binary And Store It In A String
