I'm making a program that hold a list of strings (commands) in memory, displays it with a GUI and also sends any of these strings to a USB port.
I'm thinking of holding the strings in a vector that is initialized in a class with methods to add or delete strings (commands). Should I store these string in the vector or pointers to string? Or is there a better way?
I've created a solution who exported Access reports (graphics/tables) to a Word- and a PDF-format. Therefor I use PDFSharp and PDFFocus.
The PDF document is okay. But the Word-document looks good. Only the size of the Word-document, it has to send by e-mail, is much too big (17MB).
I have to open the Word document again to change the PageSettings to be sure, that the page-margins and the print orientation are correct.
using System; using Microsoft.Office.Interop.Word; namespace PageSetup { class TestPageOrientation { static void Main(string[] args)
[Code] .....
I don't know how it works in the Word-library source. But I've tried WdOrientation.wdOrientPortrait and once I was surprised. I saw this page in Landscape-format.
I think there is something wrong with my document sections, because the documents (with a lot of tables, graphics and a image) is much too big. And that's only after using this method.
So my next question is: How can I shrink the size of this Word document?
And what do I have to do to limit the amount of format-settings in this word-document?
I am trying to write down in binary format an array of unsigned int values but i get the following compilation error :
: In function ‘int CIndex(std::fstream&, std::fstream&, std::fstream&, std::fstream&)’: ./src/IndexBuilder/index.cpp:23:26: error: no matching function for call to ‘std::basic_fstream<char>::write(int*, long unsigned int)’ ./src/IndexBuilder/index.cpp:23:26: note: candidate is: /usr/include/c++/4.6/bits/ostream.tcc:184:5: note: std::basic_ostream<_CharT, _Traits>& std::basic_ostream<_CharT, _Traits>::write(const _CharT*, std::streamsize) [with _CharT = char, _Traits = std::char_traits<char>, std::streamsize = long int]
This is the part the is not working:
Code: // uia is : unsigned int * uia; // then I have allocated the space for it // load it with unsigned int's // k is the number of variables in my array
o.write(uia,sizeof(unsigned int)*k); But thsi should be so simple and strait forward.... in c i do it as :
Code: fwrite(uia, sizeof(unsigned int), k , fp); but since i would need to convert fstream to FILE* i decided to do it c++ way.
I'm trying to create a two dimensional array that displays zeroes in a 10 by 10 format. But I don't really know how.I've been playing around and this is what I have so far:
Code:
#include<stdio.h> int main(void) { int my_array[10][10]={0}; int i,j;
Write a program using user-defined function which accepts an integer array and its size as arguments and assign the elements into a two dimensional array of integers in the following format: If the array is 1,2,3,4,5,6, the resultant 2D array is
I'm trying to put all of the words in a text document into an array but this text document is 2,138 kb, and when my program is crashing when I try to put it into an string array. Could the file be too big to put into the array?
int numbers[] = {8, 2, 0, 4, 100, 5}; for(int i = 0; i < sizeof(numbers); i++){ cout << numbers[i] << endl; }
However the results in the console is: 8 2 0 4 ,What am I doing wrong? Am I using the wrong built in function or something? I googled this and one of the links that came up stated to just do something like
arrayName.size()
but that didnt work for me either...
[URL]
Also, I know that I just enter the size of the list manually, in this case make i < 6 but I still want to know if there is a built in function or something.
I remember in C++, when a dynamic array is allocated, the size of this array is stored right before the array in memory. Therefore compiler knows exactly how long, when this array is deleted.
Do all compilers store the size this way? Is it a safe method to get the size of a dynamic array?
Here is a example code, it works fine on Visual Studio 2012.
#include <iostream> using namespace std; class dummy { public: dummy() { cout<<"dummy created"<<endl;
arrays with dynamic sizes. That being said, I'm working with a simple code which seems to work just fine, my only concern is that once I display the 'char array', not only displays the user's inputs but some extra data, symbols and what not.
why, if to my understanding the first user's input already sets the size of the array
#include <iostream> #include <iomanip> using namespace std;
char A[]={}; this is the array in c++ of unknown size, now I want to enter some alphabets via loop and want to be the no. of elements i entered the size of the array. .
The instructions call for the user to define the size of the array and all I have ever done is use a predefined size for the array and then let the user fill it. Here is what I have so far:
I am creating a class that has a private array on the heap with a constructor that takes the size of the array and initializes it on the heap. Later I have to make a deconstructor delete the space and print out free after.In my code, I was able to heap a private array and make a deconstructor, but I don't know how to take the size of the array and initialize it on the heap. My guess is this:
int* size = new int();
Also when you initialize size on the heap, don't you also have to delete it too? If so, where, in the code, do you do that? Here is my code so far.
Class Student { private: int size; int* array = new int[size]; public: Student(); // Constructor ~Student(); // Deconstructor
[code]....
How do you make a constructor that takes the size of the array and initializes it on the heap
