C++ :: Universal Order / Spacing Of Character Encoding For Integer Digits?
Feb 7, 2012
I have a char *pch that points to an integer digit 1 or 2 or ... 9. To get the character that's 1 less, instead of converting to int, minus 1, then converting back to char, I tried (*pch -1) and that seemed to work. I suppose that's because the particular character encoding on my system is such that the digits are encoded in the same order and spacing as the integers they represent. So the question is does this "convenience" feature hold true for all character encoding systems?

My problem needs to prompt the user to input an integer and then outputs both the individual digits of the number and the sum of the digits. An example would be entering 8030 and it spits out 8 0 3 0 as well as 8+0+3+0=11 and it needs to work with negative numbers.
Code:
#include <iostream>
#include <iomanip>
using namespace std;
int main() {
int base;
[Code] ....
Now I don't know if any of this is right a hint my professor gave us is that to get the fourth digit you would do base mod 10 and to get the first digit you do base divided 1000...
Code:
{
int power;
int counter=0;
int value=1;
cout << "Enter the power of 10 you want: ";
[Code] ....

I'm trying to implement a code that recursively calls itself and prints the given digits in ascending order, i.e. if the number is 5, then the function will print 1 2 3 4 5. I cannot use loops in any way!
The problem I have is with keeping my variable i at a set value each time the function calls itself.
void print_ascending(int n){
int i = 1;
if(i < n) {
printf("%d", i);
i++;
print_ascending(n);
}
}
Of course, the problem with this code is it will re-initialize the variable i to 1 every single time and infinitely loop to print 1.

Just wanted to share a program I made. It was the answer to one of the end chapter exercises in the C programming book I'm using, asking the reader to create a program that adds all the digits of an integer.
Code:
/* Program to calculate the sum of the digits in an integer */
#include <stdio.h>
int main () {
int number, right_digit, sum = 0;

I want to convert the integer into a string.
int x = 693;
char chararr[max];
In my homework, x is unknown. but don't worry, I wont ask for the full code. I just need the part where you change the int into a string/array of char.
I'm thinking in circles from where to start?

I have an integer that the user enters. I need each digit of the integer to be set as an element of an array. the integer could also be entered as an array, but I need the user not to have to enter each element and press ENTER.

Write a full C++ program that inputs three-digit integer, separates the integer into its individual digits and prints the digits separated from one another. For example, if the user types 549, the program should print;
5 4 9

I have a vector which contains vectors containing 7 integers each. I'd like to sort these vectors based on the value of the first integer (int IOT), in ascending order. I know this type of question can be found everywhere, but I'm lost as to why this doesn't compile.
#include <fstream>
#include <iostream>
#include <vector>
#include <string>
#include <algorithm>
#include <stdio.h>
#include <math.h>

how to carry out the conversions. The assignment is the normal hex to octal and Quart (base 4) via bit munipulation which I have worked out myself. However, I have been trying all day to figure out how to read in a string such as H1234, or O4567. How to parse the input I can handle the remainder myself. I'm just stuck and I've tried for hours.

I have been trying to write a function which can convert a number from an unsigned long integer to a readable ASCII character string. this is what I have come up with, but I am receiving some very strange characters in return. Could the problem be that I am telling a char to = an unsigned long int, (cString[i] = product[i])?
void convertToString(unsigned long con) {
unsigned long product[10];
char cString[10];
const unsigned long begConvert = 10 ^ 10;

The function uses a "for" loop to print the given character the number of times specified by the integer.
How can I make a for loop to do that?
So.. my code looks like this:
// cpp : Defines the entry point for the console application
//
#include "stdafx.h"
#include <iostream>
using namespace std;
void printMyInteger(int myInteger, char myChar) {
[Code] ....
So.. here is my error:

I need to create a line chart that will be universal for every currency. As Y it will display value of currency, as X it will display time when that value was established.
For drawing I think of using Windows.UI.Xaml.Shapes.Line and Windows.UI.Xaml.Controls.Canvas
What I want to get is something like image below but it would have to draw correctly scaled chart for every currency which is the biggest problem(I think it is).
For every currency I will probably have to get minimal and maximal value which will be used to properly scale a chart(I will probably also have to get rendersize of canvas or something).
The user will choose the range of time and then the correct chart must be drawn (For example 04-11-2004 to 11-03-2007)
It is a windows store project.

I am working in an assignment and part of this assignment is to input a CSV file with floats such as this:
8.5, 10.5, 90.5
49.5, 99 ,97
88, 70, 100
78, 2, 10
into an universal variable array.I just want to figure out a way to simply input the CSV file into a 2D variable array.The values in the array will be later use in functions that I'm trying to figure out but I can't do that until I store these values in the array. I think is just a matter of figuring out how to tell fscanf to ommit spaces and commas, but I don't know how. This is what I have done
Code:
#include<stdio.h>
#include<stdlib.h>
#include<math.h>
float grades[1001][101];
int main(int argc, char* argv[]){
[Code] ....
The output is this
Assignment 1 of student 1 = 8.5 Assignment 2 of student 1 = 10.5 Assignment 3 of student 1 = 0.0 Assignment 1 of student 2 = 90.5
I think I'm close to solve it but something is missing the output should look like this
Assignment 1 of student 1 = 8.5 Assignment 2 of student 1 = 10.5 Assignment 3 of student 1 = 90.5 Assignment 1 of student 2 = 49.5

I'm expected to write a c program for this question :
Using these header files
#include <stdio.h>
#include <conio.h>
Question : Write a program that will prompt the user to enter an integer value and a character code to indicate whether they want to do a Kilogram to Pounds conversion (A) or a Pounds to Kilogram (B) conversion. Note that 1 kg = 2.2 pounds. The program should then do the necessary conversion indicated by the code and display the newly converted value to the screen.

I have an QHBoxLayout that includes two QLabel Widgets. My left QLabel is much larger than my right QLabel, however, the QHBoxLayout is splitting the output in half, so the left side of the layout is too small and the right side of the layout is too big. How do I modify the QHBoxLayout to create unequal proportioned space for each included widget?

I have an MDI MFC application which has a menu at the top. Nothing particularly unusual about that, but for some reason my application seems to have a vertical spacing about 30%-40% bigger than "normal" on the drop down menus (when compared with Visual Studio itself).
I've looked thru the options for CMenu, CMFCMenuBar, CMFCVisualManager, but can't seem to find anything to explain why my menu has such a large vertical spacing between options, nor how to change it.

The program should store a character array in reverse order then display the reversed array. I have also included in the code that will display the actual characters into the array as it loops through. So I know the characters are being stored, but why doesn't it display the entire string when I call it?
Code:
#include<stdio.h>
int main(){
char str[50];
char rev[50];
printf("Enter Desired Text: ");
scanf ("%[^

Is it just my compiler?

So I have to write a program that outputs a check with correct spacing and everything.
Create a project titled Lab7_Check. Write a program that asks the user the check information and prints the check. The dialog should be as follows:
date: 2/23/2010
name: William Schmidt
amount, dollars: 23
cents: 30
payee: Office Max
your check:
William Schmidt 10/13/2013
pay to: Office Max $23.30
twenty three and 30/100 dollars
You may assume that a person always has the first name and last name (no middle names or initials). The payee name is also always two words. The dollar and cent amount are integers and the amount is always less than 100 dollars. Note that the dollar amount could be zero, in which case, when you spell the dollar amount, it should print "zero". The date is always a single (non-white space separated string). Your date, dollar amount in numbers and the word "dollars" have to vertically align.
This is the code I have so far.
#include <iostream>
#include <string>
using namespace std;
int main(){
string date;
string firstname;
string lastname;

I've got an application here which connects over the internet to a webserver and sends some json strings. This is all working already.
Now I want to encode one string via mcrypt (because it seemed the easiest library of all) AES and send it over to the other server where it should get decrypted again and checked for validity.
I'll be using this sample code as "starting base". i've found it on the internet:
Code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
/*
* MCrypt API available online:
[Code] ....
The code works as it is, it encodes my string into a ciphered text and displays the text via the display function to stdout.
From previous projects I know I usually used Base64 for transporting strings via json, but in this example the string is encoded into "%d" - so decimals.. It works too, and I dont care if I send a base64 encoded string or these decimals but how would I calculate back the %d encoded string ? So how would a "undisplay()" class look alike ?
Or maybe there is an easier way to transport the string and re-decode it ?
I'd expect something like:
base64string = base64encode(ciphertext);
...
send base64string to host2
...
at host2:
ciphertext = base64decode(base64string)
...
and then mcrypt_decode that ciphertext...
