C++ :: Convert From Integer To Character String

Oct 2, 2013

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;

C :: How To Read In A Character Followed By Integer Without Space

Feb 13, 2014

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.

C/C++ :: For Loop To Print Given Character Number Of Times Specified By Integer

Feb 11, 2014

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:

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?

C/C++ :: Convert Integer To Its 2 Complement

Feb 12, 2014

I have to implant a code to convert any integer to its 2'complement. I have already finished the first and the second part, which was to convert the integer to its binary representation, then to invert each digit in the binary representation. The third part is to add 1 to the binary representation.

// the last step is to add 1 to the binary number
int carryIn=0;
int carryOut;
for(itr= bainaryList.begin(); itr!= bainaryList.end(); itr++) {
//start comparing the possibilities of the values in both lists
if (((*itr)==0) && (carryIn== 0))

Visual C++ :: Prompt User To Enter Integer Value And Character Code To Indicate Conversion

Sep 14, 2013

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.

Visual C++ :: Convert MM/DD/YY Hh:mm Stream To Integer?

Nov 7, 2012

I'm trying to read in two instances of date and time (from user input) into a string value (MM/DD/YY hh:mm).
I need to be able to calculate the difference between the two in order to return how much time has elapsed from the first date/time to the second date/time.

What would be the most efficient way to go about obtaining said results?

I was thinking I need to convert each year, month, day, hour, and minutes into its own integer variable, after researching immensely online I'm still not sure how to convert from a string of characters to an integer.

C++ :: Convert Positive Integer Into Its English Name Equivalent To Digit?

Jul 13, 2014

convert a positive integer code into its english name equivalent for digit. A valid code is of size between four (4) to six (6) digits inclusive. A zero is not allowed in the code.

example : if the input is 234056 the output is : INVALID CODE (PRESENCE OF ZERO)
if the input is 23456 the output is : TWO THREE FOUR FIVE SIX
if the input is 9349 the output is : NINE THREE FOUR NINE
if the input is 245 the output is : INVALID CODE (3 DIGITS)
if the input is 2344567 the output is : INVALID CODE (7 DIGITS)

step 1 : input code
step 2 : count the number of digits in the code
step 3 : if there is a zero in the code, "INVALID CODE (PRESENCE OF ZERO)" go to step 4
step 4 : if number of digits is mode or equal than 4 and less or equal than 6, go to step 5 else display the following message "INVALID CODE (<number of digits> DIGITS)
step 5 : call a function called digit_name to convert each digit into its
equivalent english name. display the result
step 6 : print the digits in reverse order
eg; if input is 13453, reverse order is 35431

C :: Accept Input Number From User And To Convert It Into Array Of Integer

Oct 7, 2014

i was trying to solve a problem in SPOJ and what i wanted to do is to accept an input number from the user and to convert it into a array of integer.

Code:

#include<stdio.h>
int * toarray(int *num);
int main(void)
{
int testCases;
}

[code]....

But whenever i try to print the array in the main function i get only two value and the rest address

Code:

1//number of testCases
23456 //input number
6
2293452
4
2293700
1974439125

Process returned 0 (0x0) execution time : 4.152 s
Press any key to continue. However, if i tried to print the array from within the function, it prints the numbers just fine.

print the array elements from the main program, so that i would be able to go on with the rest of it
