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)
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;
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.
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....
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.
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;)
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
