Visual C++ :: A Class For Operations With Large Integer Numbers?
Nov 27, 2012
Why this class doesn't work for Subtraction, Division and Square Root. When I try to get results for Subtraction, it output right answer, but with any trash. And When I try to get answer for Division and Square Root, it just brakes and don't output anything. For Addition and Multiplication class work correctly.
changing a 9 digit integer into a new 9 digit integer through simple mathematical operations. For example, I need to change 123456789 into the new digit 456123789. Sometimes I need to change a 9 digit integer into an 8 digit integer. An example is 789062456 into 62789456. I can ONLY use simple mathematical operations (addition, subtraction, multiplication, division and modulo).
If i m writing a code for a program to solve factorials, what is the best approach if i have large numbers in mind?
If i use int, i can only go upto 4bytes and if i use double i can go upto 8bytes. so should i create new type or is there any other way to get this done.
I'm programming an app that deals with large numbers. I have a do-while loop that I want to execute. I can not get it to work. The "while(d!=1)" part is the problem and I can not find a way around.
Code: #include "stdafx.h" #include <stdio.h> #include <gmp.h> #pragma comment(lib, "gmp.lib") int main (int argc, char *argv[]) { mpz_t d;
[Code] ....
I get errors:
1.error C2446: '!=' : no conversion from 'const int' to '__mpz_struct *'
Conversion from integral type to pointer type requires reinterpret_cast, C-style cast or function-style cast
2. '!=' : '__mpz_struct [1]' differs in levels of indirection from 'const int'
I am working on a program which creates a large pointer array of numbers and then performs several iterations of operations in them.
Code: int * u = new int[N]; double * nu = new double[N]; int * nud = new int[N]; for (int i=0;i<M;i++){ for (int i=0;i<N;i++){ u[i]=0; nu[i]=0;

If M is small enough then there are no problems in the program. However once M is large enough I get the "unhanded exception":
std::bad_alloc at memory location 0x0026f728..
Since I am just reusing the same arrays, and since I am able to make it through a few iterations, I didn't think it could be a memory issue. If it is, is there a way I can clear the data completely after each iteration?
Trying to write 4 bytes ints in a binary file and extract them after... I'm using the exclusive or (^) to isolate single bytes to write to and extract from the file since the write() function accepts only chars, only the beginning and end results are not the same...
I have to write a program where the user will input integer numbers. How many numbers they enter is unknown, therefor you should use a repetition structure for the input. When the user is done, they will enter -1 to exit.
Create a dynamic array if the size=2( the initial size must be 2) Repeat until user enters -1.
I have to do this without using vectors.
This is what i have, I cannot figure out what to put in main. I was thinking of a do-while?
Code: #include <iostream> using namespace std; void resize(int *[], int); int main() { int *listDyn; int size=2;
My code handles smaller numbers well enough, but I need the program to be able at least factor 100!.
#include <stdio.h> void factorialOutput(unsigned int &n, int fac[]); unsigned long long factorial(int n); int main(int argc, const char * argv[]) { unsigned int t = 0; int n[101];
I have to write a program, that multplicates very large numbers (out of range of long int). It's said that i need to use arrays and read the numbers as strings. My problem is to end function called "mnoz:, because i don't know how to sum the multiplicated values of arrays a and b.
I tried to sort a large numbers of vector of random integers with std::sort(), but when the number increases over 10M, std::sort returns all zero in values. Does std::sort have a limitation of input numbers?
I'm trying to make sure my code is written in smaller modules, so my first step is to create my initialization process in and external file to load the necessary data from external sources and set up things like the content of drop down list boxes.
My first attempt failed to give me access to the combobox items add function so I moved that code back into the form1.h file:
Code: public: Form1(void) { InitializeComponent(); // //TODO: Add the constructor code here // } void AddDate(char *date, int ID) { this->comboBox1->Items->Add("line 1"); }
It compiles fine, but the call to it in my Initialize.cpp file
Code: MarketView::Form1::AddDate("abs",1); Gives error C2352: 'MarketView::Form1::AddDate' : illegal call of non-static member function
OK, so I change "void AddDate" to "static void AddDate" and now get the error that "static member functions do not have 'this' pointers" so I go back to the "MarketView::Form1::comboBox1" situation where there is no legal syntax after "Box1 to get me to Items->Add
I've been an old fashion programmer for over 47 years. It seems as is the concept of programming computers has changed from the concepts of logic to memorization of complex syntax.
There has to be a simple answer to do this other than to write thousands of lines of code in one Form1.h file. I refuse to believe that the new programming concepts will not allow you to write code in smaller more manageable modules.
What is the proper syntax for breaking up the larger file into more manageable chucks?
I'm having problems with progress bar when using a big number in set range. For numbers below 50000 it works very well but for big numbers like 100.000 it doesn't work, it makes 2-3 rounds of animation
Code: int number= 50000; // 50k works well but if i put 100k it won't work (it will animate 2-3 rounds instead of complete one) progressbar1.SetRange(0, number); progressbar1.SetStep(1); for (int i = 0; i < number; ++i) { listcontrol1.InsertItem(i, _T("whatever")); progressbar1.StepIt(); }
Opening large files in c++. In my application, i am trying to save video as long as users have space in harddisk. What I am trying to do is when user is recording video i am trying to append the video data in to the file. The problem is that every time file size reach over 2GB my software crashes.
i'm having difficulty with a problem, i need to add two big numbers suchas 54646774456776 and another one 445556777554 and it would print the result. how can i approach this problem without the use of arrays?
I'm supposed to write a code that takes an integer and splits it into individual numbers e.g. 234 becomes 2 3 4 .the individual numbers are then passed on to a function that accepts only one number at a time
All i could think of was this,but its a very bad method coz i dont know how long a number would be inputed into "Angle_in_degree"
I want it to store the integers as bits so that I am move them over and store them farther down the row as more numbers are added, but instead each new number is being added to the previous and I'm just getting a larger integer. Is this even a feasible way to store integers within an integer?
