C/C++ :: How To Space Out Binary Numbers
Nov 13, 2014
I am having trouble finding out how to space out the binary numbers that I am displaying. Currently they are displaying all as one EX: 10001000
How can I get them to be space out properly like: 1000 1000?
Im guessing its something in my loop. Here's my function for converting to binary:
void DisplayBinary(int num) {
int ctr;
unsigned int mask = 32768;
printf("
The input number in binary is: ");
for (ctr = 1; ctr <= 16; ctr++) {

If every record of a binary file is to be fixed length then shouldn't some space be wasted if variables are different size in a struct?

I have a program in c++ to print all the binary numbers that have 64 bits. But the problem is it works only for 30 bits. Beyond that the program does not work possibly because of insufficient space availability.
my code is as below:
// C++ program to generate n-bit binary numbers
#include <iostream>
#include <string>
#include <vector>
#include <fstream>
using namespace std;
// This function generates all n bit Gray codes and prints the generated codes
void generateSequence(int n)

This is supposed to read a series of 16 bit binary numbers as short ints in the array memory. However, it only appears to be reading the first number.
Code:
short int memory[256];
void readFile(){
//read input file into int memory[]
FILE *ifp;
ifp = fopen("proj1a.dat", "r"); //input file

The code should convert binary numbers to decimal but it doesn't..
Code:
#include <stdio.h>
#include <math.h>
#include <string.h>
int main()
{

This is the question: [URL] .....
Now I have the binary numbers printed out in my code, but I don't know how I can covert them into to decimal.
#include <iostream>
#include <iomanip>
#include <string>
#include <cmath>
using namespace std;
int main() {
int numberOfDigits;
int numberOfRows;
char flag;

I wanted to know if it is possible to read binary numbers(0's and 1's) from a file(text,picture, anything), and see them in the compiler.

So 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.

Create a program that will ask the user to enter a decimal value (1-999999) then display its corresponding binary numbers. Repeat this process until the value entered is equal to 0. Use the following Function Prototype:
void BinCodes(int value);
Sample Input/Output:
Enter a Decimal: 35
Binary: 100011
Enter a Decimal: 184
Binary: 10111000
Enter a Decimal: 0

I have tried to understand the concept of linked lists and I have read the assigned chapter 2 times. My teacher is a little laid back when it comes to teaching! This is only a portion of my program. This function is supposed to add 2 binary numbers 11101+1101 and store the result in the temp list. The answer I get is 10000.I don't think that it is adding the carry.
binary operator+( binary num1, binary num2) {
binary temp;
int carry, sum;

I am trying to make a program that will convert a list of binary numbers from a file into decimal and print the decimal to the screen. I have no problem doing the conversion, the problem comes up when our teacher wants the input file in a format as such:
3
10110101
11111111
10101010
The first number is supposed to tell the program how many different 8bit strings it is going to have to convert, and then the following lines are those binary numbers.
I am not very experienced with file inputs, and I know how to open files and read lines in.. The problem is, how to say "ok the first line says 3, so now I have to convert the next 3 lines" . I am assuming it is just a simple loop that I am missing....

how to input with space what i mean is like this, for example:
Product Code: 0000001
Product Name: Mobile Phone
if the users input is like that in the (Product Name)it will skip the next input that is the
Price: Quantity: 100
Manufacturer: Alcatel
something like that...
Heres the code
Code:
if(b<=10)
{/*Start for IF Statement*/
for(a=1;a<=b;a++)
{/*Start of FOR loop*/
printf("
");
printf("Product Code : ");
scanf("%s", &prod_code);
}

I used pointer(or is it not?) to make it one part only alphabets and the other one digits. The coding, calculate_charges.c and the open file, customer.txt are attached at the end of the post.
Code:
#include <stdio.h>
#include <string.h>
#define SIZE 3
void trimback(char input[], int strnameindex);
void trimfrnt(char input[], int strnameindex);

What would the worst, average and best case space complexity be for a data structure of type map<string, vector<int> > in big O notation? I'm parsing through a document and storing each word as a key and im attaching an associated int (in a vector) to it as the value.

Can we use using declaration within name space scope? is it safe to use it?
I think we can use using declaration for class scope and function scope only.

I want the user to be able to enter a command then a character, like for example: push r....I want the command to be stored in the array command, and the character to be stored in the variable c.
Now I wonder what the best way to get rid of the space is, using scanf or getchar (see below for code, only thing that I changed between the 2 versions is the statement before the comment "get rid of space")? Or maybe it doesnt matter?
Code:
include <stdio.h>
#define MAX 200
void push(char c); // Puts a new element last in queue
char pop(void); // Gets the first element in queue
static char s[MAX];
}

I am allocating space only for two characters but it fits all of them, if you run this it will print the whole string literal "hello my friend". How is that possible?
I am using gcc 4.6.3., I know about strncpy().
#include<iostream>
#include<cstring>
using namespace std;
int main(){
char* str = new char[2];
strcpy(str, "hello my friend");
cout << str << endl;
return 0;
}

how can I read some strings that contains spaces and put them in a vector of strings, using the push_back() function?
I have a collection of functions, for example: [multiply_by_forty two, add_by_five]. All I want to do is to store the strings like: multiply_by, add_by in a vector of strings, and the arguments:forty two, five etc in another vector of strings, but with spaces. The function convert() converts written numbers to numbers (for ex the output of covert("forty two")is 42;)
Here is the code:
public:void split() {
vector < string > s1;
vector < string > s2;

In my code I have a template class.
In the contructor, I create a new array arrray.
A pointer to this array is saved as an attribute.
The purpose of this attribute is that I should be able to call the array from within another function be typing *p or *(p+1) etc.
The only thing I forgot is that the array doesn't exist anymore when the constructor is done, right?
This means the space is no longer reserved for this array and the space is used for other things.
Is there a way to keep the array space reserved (even when the array does not exist anymore at the end of the function)?

I have a problem, caught the last line of a file and do the division of the same variables in, date, time and value, but the file contains excess spaces in all lines and the date is coming with cuts, example 24/4/2014 appears 4/4/2014. How can I remove the space in the string without affecting the division of the line?
if (file) {
std::string line = getLastLine(file);
std::istringstream iss(line);
getline(iss, date, ' ');
getline(iss, time, ' ');
getline(iss, t); //variavel para temperatura em string
}
else {
std::cout << "error file

I'm really new to SDL and i've been trying to make a spaceshooter game, so far I've got a ship you can move around in using the arrow key (square shaped) and a scrolling background. I'm up to making my ship fire bullets at the moment and it's really not working, i've finished lazy foo's tutorials on SDL and there's nothing on this.
Here's my code
#include "SDL.h"
#include "SDL_image.h"
#include "SDL_mixer.h"
#include "SDL_ttf.h"
#include <string>
const int SCREEN_WIDTH = 640;
const int SCREEN_HEIGHT = 480;

I have created a prompt which prompts the user for an integer and I have set up a loop to check for if it is an integer or not. My "bug" is that a user can enter an "integer" and "space" and "enter" and it does not give any error and assumes that "All is FINE!". I have gotten the value from the ascii table of 'SPACE' and put it as a check in my parameter of while, but it does not work.
Here is my code:
int x, y, boolean, i;
char buff[256];
printf("Enter the first integer value: ");
scanf("%s", buff);
i = 0;
boolean = 0; //initializing our boolean var that will eventually decide if we have an error or not
