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 have an assignment where I have to design, implement, and test a class for storing integer arrays "safely". I do not know how to set up the destructor.
The goal of this programming assignment is to give students practice defining and using classes. In particular, students are required to design, implement, and test a class for storing integer arrays "safely". The array should be able to hold any number of integers up to 100.
In the class header file "SafeArray.h" students must define the class and specify the constructor/destructor functions, the public methods and private variables. In the class implementation file "SafeArray.cpp" students must implement the following operations:
constructor - to initialize the object.
copy constructor - to copy an object.
destructor - to delete the object.
set - allow the user to set a value of the array at a particular location.
get - allow the user to get a value of the array at a particular location.
print - print out the array.
add - add the elements of one array to another.
subtract - subtract the elements of one array from another.
The purpose of your main program "main.cpp" is to demonstrate that all of the methods above work properly. You should have at least one call to each of the methods, and print out the array as needed to show that the operations are performing correctly.
"SafeArray.h":
#ifndef SAFEARRAY_H
#defineSAFEARRAY_H
class Safe {
private:
// Declare variables to store A, B and C

Ok so I am currently trying to add and subtract two sets of integer arrays. When I run my program, the program does not subtract the numbers from the first set with the numbers from the second set. Could anyone here take a look at my code and help me figure out what the problem is?
#include <iostream>
#include "SafeArray.h"
using namespace std;

I am currently working on a program that uses a class to store integer arrays. I have most of the code done, but I am having trouble on the main.cpp part of my program. The program should display this:
OBJ 1:
2 3 4
OBJ 2:
1 4 -2
Addition:
OBJ 1 =
3 7 6
Subtraction:
OBJ 1 = 1 -1 6
But when I run and compile my program, this is what I get:
OBJ 1:
2 3 4
OBJ 2:
ADDING:
OBJ 1 =
4 6 8
Subtraction:
OBJ 1 =
Here is my current main.cpp:
Code:
#include <iostream>

I am currently stuck on what I should do next in a program I am working on. These are my instructions:
Design, implement, and test a class for storing integer arrays "safely". The array should be able to hold any number of integers up to 100.
In the class header file "SafeArray.h" students must define the class and specify the constructor/destructor functions, the public methods and private variables. In the class implementation file "SafeArray.cpp" students must implement the following operations:

set - allow the user to set a value of the array at a particular location.
get - allow the user to get a value of the array at a particular location.
print - print out the array.
add - add the elements of one array to another.
subtract - subtract the elements of one array from another.
The output of my program is suppose to look like this:
Set q1: 2, 3, 4
Print q1: 2, 3, 4
Set q2: 1, 4, -2
Print q2: 1, 4, -2
Add q2 to q1
Print q1: 3, 7, 2
Get q1 at 1: 7
Here is the code I have so far.

#include "SafeArray.h"

int main() {
// Declare a SafeArray object

Passing and returning character and integer arrays with functions using simple programs...use pointers if necessary
View 1 Replies View RelatedI'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"
Code:
int Angle_in_degree,a,b,c
c= Angle_in_degree %10;
b=Angle_in_degree/10 %10;
a=Angle_in_degree/100 % 10;
function(a);
function(b);

I am writing trying to store a list of numbers into an integer as bits. So far I have this:
n=n & 0x0f
integer = integer<<2
integer = integer | n;
convert(integer));
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?
Alexandra has some distinct integer numbers a1,a2...an.
Count number of pairs (i,j) such that:
1≤ i ≤ n
1≤ j ≤ n
ai < aj
Input
The first line of the input contains an integer T denoting the number of test cases. The description of T test cases follows. The first line of each test case contains a single integer n denoting the number of numbers Alexandra has. The second line contains n space-separated distinct integers a1, a2, ..., an denoting these numbers.
Output
For each test case, output a single line containing number of pairs for corresponding test case.
Constraints
1 ≤ T ≤ 4
1 ≤ n ≤ 100000
0 ≤ ai ≤ 109
All the ai are distinct
Example
2
2
2 1
3
3 1 2
Output:
1
3
Explanation
Case 1: Only one such pair: (2,1)
Case 2: 3 possible pairs: (2,1), (2,3), (3,1)
as I understand the problem is just counting how many Ai's are 1 <= Ai <= N and then apply ((R*(R-1))/2), R is the count of valid Ai's

#include <stdio.h>

Write a C program that sorts an unsorted array of 5 integer numbers in ascending order by swapping numbers repeatedly. Specifically, first prompt the user to input 5 numbers and store the numbers in an array. Then, if the numbers in the array are not in ascending order, ask the user to provide the indices of two numbers in the array that the user wants to swap. If the user does not enter valid indices (i.e., outside 0 to4), then re-prompt the user to enter new indices. Continue prompting the user to provide indices of numbers to swap until the array becomes sorted in ascending order. Finally, when the array becomes sorted, the program should print "The array is now sorted in ascending order".
Implementation Requirements
Use the #define directive to define the size of the array.
Implement a function called "checkArrayOrder" to check whether an array is in ascending order or not. The prototype of the function is
"intcheckArrayOrder(int arr[], int size);". The function should return
1 if the array passed to the function is in ascending order0 if the array passed to the function is not in ascending order
Define the function prototype in your program.
Implement a function called "swap", whose prototype is "int swap(int arr[], int size, int i, int j);" which swaps the numbers in positions "i" and "j" of the array passed to the function and returns
1 if the indices"i" and "j" are within bounds (i.e., between 0 and 4) and the swap operation is performed correctly.
0 if the indices"i" and "j" are outside bounds so that the swap operation cannot be performed.
Define the function prototype in your program.
Use the function "checkArrayOrder" whenever your program needs to check whether an array is in ascending order or not; and the function "swap" to swap the numbers the user specifies (Note that, you should check whether the user provided indices are valid inside the function "swap" and not inside "main").
here is my code so far
Code:
#define ARRAY_SIZE 5
void main()
{
int i, array[ARRAY_SIZE];
printf("Enter %d numbers
", ARRAY_SIZE);
for(i=0; i<ARRAY_SIZE; ++i)
scanf("%d", &array[i]);
[Code] .....
I'm just not sure how to proceed. I'm not really sure how to progress the checkArrayOrder function to the swap function (in the if statement).

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.

I was going through a book I have about C trying to learn about arrays, and one of the first few examples of what could been done with an array was showing how to use an array to generate a list of prime numbers. I've been staring at this program for about an hour trying to understand how it works (it does), but the workings of one for loop within the program.
Code:
#include <stdio.h>
#include <stdbool.h>
int main () {
int p, i, primes[50], primeIndex = 2;
bool isPrime;
[Code]...
So that is saying in order for this loop to go on, really two conditions must be met since there's that && operator. isPrime must be true (I think that's what it means by just having "isPrime" and not setting it equal to anything) and p / primes[i] must be greater than or equal to primes[i].So at the beginning of the loop, since i = 1, p = 5 (as per surrounding loop), and prime[i] = 3 ( as per the variable assignment at the beginning of the program ), the loop condition would be "isPrime && 5 / 3 >= 3"
"5 / 3 >= 3" The loop should stop right there! 1.666666667 is NOT greater than or equal to 3!
Ok so Im suppose to make this program were the user inputs the size of the array then the user sets a certain range min and max for random numbers to be generated. I have a function named fillarray()
#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;
int fillarray();
[Code] ....
Whenever i run the program i keep on getting a loop for the size of the array.
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;

I have a set range, say 10 to 100, and I'm trying to separate the numbers evenly into 5 arrays. So there are 90 numbers, how can I assign 10 - 27 to the first array and the next 18 numbers to the next array without creating separate loops for each one?

How am I able to fix this code to do what I want? The purpose of my program is to enter in positive numbers in an array (and having it end when 0 is typed) My program also accepts negative values but will ignore them when it is outputted. I believe I have all the code right except for line 21.
#include<iostream>

I want to have the random numbers between 1 to 5 for a variable of 5arrays. for having the random numbers i am using the code as below.
Code:
for(int i=1;i<=5;i++)
{ int j=rand()%5;
cout<<j<<endl;
}
The problem with this way of generating random number is that i get the same set of random numbers in every outputs. Is there any other way to have different random numbers with many different outcomes as much as possible.

array2[40];
array1 array2// array1 array2// array1 array2 // array1 array2 // array1 array2
array1 array2// array1 array2// array1 array2 // array1 array2 // array1 array2
array1 array2// array1 array2// array1 array2 // array1 array2 // array1 array2

how can i put this in a loop?
and so on but there are 80 elements so i cant go one by one.
