C++ :: Converting Characters To Numbers Using Data Files
Feb 20, 2013I need to convert characters in a input file to numbers in output file and display both the characters and numbers in a console window.Only 7 numbers can be displayed, the rest needs to be dropped.The input file contains the following data, with one number per line:
CALL HOME
GET LOAN
Hi THERE
BYE FOR NOW
For example, once the first number in the input file has been processed, the console window should display the following: CALL HOME 225 5466.
The output file should now also contain the number:
225 5466
Currently my console is displaying the following:
Enter the input file name.
infile.txt
Enter the output file name.
outfile.txt

C++ :: Create Main Function With One Dimension Dynamic Array With Float Data Type
Dec 4, 2013I need to create a main function with a one dimension dynamic array with float data type. The total number of array elements must be controlled by a user input from the keyboard.

I understand how to create dynamic array but not where the user inputs the length of the array. How would I implement this?

C++ :: Handy Function (or Library) For Converting Between Different Text Formats?
Feb 3, 2015know of a handy function (or library) for converting between different text formats? I've heard of a library called iconv but I've no familiarity with it. However, it looks promising (from what little I can find out about it...)
Specifically, the text %20 is often used in hypertext to indicate a space character - so the string "Hello There" would get changed into "Hello%20There". How can I easily change between one and the other?
Obviously I could use string replacement functions but that'd need me to anticipate every potential hypertext code sequence.
C++ :: Converting From Class Array To Int
Mar 24, 2014Version 1 (works fine)
Creating array in main and then calling a sorting function from sorting class.
In main:
const size_t SIZE = 100;
int *array = new int [SIZE];
//fill array with ints, not shown here
quickSort(array, SIZE); //calling the sorting function in the sorting class
In the sorting class, quickSort is declared as such:
void quickSort(int arr[], int num);
Everything works great.
Version 2 (issues)
Instead of creating the array in main, I have set up a class for the array, MyArrayClass, where I create an object containing the array of ints. So far so good. The issues come when I write a member function to call quickSort. Even though my MyArrayClass object contains an array of ints, the code calling for quickSort() won't compile as the data type isn't ints but MyArrayClass (which in turn holds ints though). The compiler (using VS 2013 btw) complains that quickSort can’t convert the first argument from 'const MyArrayClass' to 'int[]'.
How do I cast my class object array of ints as an int[] in order to be able to call the quickSort function? Or should I solve this issue in some other way? I tried altering the sorting function to accept the object as it is, but that only created an avalanche of new errors, so thinking that converting/casting the object array --> int[] might be easier...

C++ :: Converting String To Char Array
Mar 30, 2014In this program, I have to ask the user for an employee, then the program will check to see if the file for that employee exist, if it doesnt then it will automatically create the file.
ReadNew function reads the file....check to see if it exist
CreateNew function creates a new file.
In my code I have no problem with the first part of reading file.. and my createnew function works in other programs where I am asking for input of file name to create the file name. However in this code I cannot figure how to automatically pass the input filename from the ReadNew function to the CreateNew function. I can't ask the user to enter the name a second time, so I have to pass the input filename into both functions. Here is my code.
Code:
//Create a file, append to it, and read it.
#include <iostream>
#include <fstream>
#include <string.h>
#include <stdio.h>
using namespace std;
char filename[256];
string n;

C++ :: Typecasting Char Array To Int (Not Converting)
Jun 1, 2014I am looking for the correct syntax to typecast a character array as an int. So I would be able to do something like this:
char ch[4];
//...Read characters from file into ch or something, etc...
int i = ( int ) &ch;
or
char ch[4];
//...Read characters from file into ch or something, etc...
int i;
strncpy ( ( char* ) &i, ch, 4 )
I want all the 4 characters ( or bytes ) of ch to be classed as an int. So we are taking the 4 bytes of the character array and placing them in 4 bytes of the integer? How would i go about this?
C/C++ :: Converting 2D Array Code To Malloc
Mar 2, 2015I made a program that adds two matrices and displays their sum with a max dimension of 100.
/* This program asks the user for 2 matrices called A and B, as integers,
and displays their sum, C. The max dimension of each matrix is 100. */
#include <stdio.h>
// Construct function
void construct() {
int m, n, i, j; // Variables
int first[100][100], second[100][100], sum[100][100]; // Matrices variables
[Code] ....
Now I need to change it so there is no max size for each matrix. The arrays will be larger than 100x100 so I need to use malloc to create my arrays. So I cant use int A[rows][cols]. This is what I did to covert arrays to malloc. It compiles but it crashes after I entered all the integers.
/* This program asks the user for 2 matrices called A and B, as integers,
