C++ :: Adding Number To All Of Its Precedents
May 1, 2014I have this program thats supposed to add a number to all of its precedents. so if the input was 5, it would add 5+4+3+2+1 and give 15. I know i can implement this in a billion different way and it wouldnt be much of a challenge, but im really confused as to why this isnt working. It gives a large negative number when i run it.
#include <iostream>
using namespace std;
int main() {
int b;
cout<<"Enter a number, ill return that number plus every number below it: ";

C++ :: Reading Unknown Number Of Inputs And Adding Them In Vector
Jan 16, 2013Consider the following piece of Code:
int ReadNumbers() {
int num;
vector<int> x;
cout << "Enter Numbers" << '
[Code] ....
The while loop is expected to terminate when the user provides an Invalid Input. But this while loop behaves unexpectedly when the user provides a 'Newline' input (by pressing Enter) and becomes an infinite loop. How can I prevent this from happening? Also I've heard that expecting invalid inputs isn't good code design. Is this true? If yes, then how can I solve my question without expecting Invalid Inputs?
Visual C++ :: Adding Rational Number Using Only Class Functions
Feb 22, 2015I'm having trouble finishing this program. What I'm trying to do is create a class for Rational numbers. Get input from user for denominator and numerator. Store the numbers without a sign, and for the sign store it separately in char. I'm not supposed to use accessor functions. The part that I can't seem to know how to do is use the info that was stored in the addUp function. This function need to add two rational numbers. i need to make this function general enough that it can handle two fractions, or a fraction and a whole number, or two whole numbers. What I already have here is readin function which reads in the numerator and denominator. setnumerator and setdenominator to assign positive values. setsign should get the sign of the fraction. Finally addUp should addUp which I explained before. I have some ideas about writing the tests, but can't seem to know how to implement it to the program. The main program is still empty but all I'm supposed to do there is call the class functions.
Code:
#include <iostream>
using namespace std;
class Rational {
private:
int numerator, denominator;
char sign;

C++ :: Adding Each Value From Array?

C :: Adding Prefixing Array
Sep 28, 2013I am trying to convert a string Input by user into an unsigned byte array.The data would be in hex form like :- "AE 1F 2C". I am thinking of using strtok to split the string into be " ". and then cast to (unsigned char *) . But for that I''ll have to prefix every element with 0X Is there any convenient way and elegant way to do this?

C++ :: Adding Entry Into Array?
Aug 6, 2014My program is suppose to be as a virtual phone book that allows you to add,search, display names and numbers.
At the beginning you are able to add up to 10 entries and then from there the program goes to a menu where you can add more entries, search etc.
My problem is that I am unable to add an entry into the existing list of names/phone numbers.
Example: At the beginning I add Joe,Albert,Barry. It sorts them into Albert, Barry, Joe (good so far!)
However, if I choose to add another entry (Carl) it becomes Barry,Carl,Joe.
The functions I am using to add entries are: GetEntries (for initial entries) and Addentries for more entries during the main program.

C :: Adding Elements To Array Of Structs
Mar 6, 2015I have a structure product_array *pa that contains a pointer *arr to an array of structs and count that adds 1 when a new product is added (set to NULL initially). I have to write a function which adds a new product entry to that array. One product entry has *title, *code, stock and price parameters. The array is dynamically allocated and I’m supposed to:
1. Reallocate space for array.
2. Update product_array.
3. Initialize it.
Also, code should be truncated to 7 characters.Products can be added multiple times, so the initial size is unknown.
Code:
void add_product(struct product_array *pa, const char *title, const char *code, int stock, double price)
{
for (int i = 0 ;; i++){
pa->arr = realloc(pa->arr, sizeof(struct product_array));

C++ :: Recursive Adding Elements In Array?

C++ :: Adding Char Array With Macro?
Dec 30, 2013The book uses this example:
#define ALLOCSIZE 10000 /* size of available space */
static char allocbuf[ALLOCSIZE]; /* storage for alloc */
static char *allocp = allocbuf; /* next free position */
char *alloc(int n)
/* return pointer to n characters */
[Code] ....
The logic here I don't understand:
if (allocbuf + ALLOCSIZE - allocp >= n)
allocbuf is a char array allocated with 10000 positions. We add that to ALLOCSIZE macro which is 10000. Does that return a value of 20000? If so, it doesn't make sense to do this because all we had to do was this:
if (allocbuf - allocp >= n)
That takes length of allocbuf which is 10000 and subtracts allocp from it. So if allocp is 1000 we are left with 9000 available slots. And we can use that to check if we have enough to allocate n elements.
C :: Array Of Structs (adding / Deleting Elements To A File)
Sep 20, 2013I want to write a program to record my neighborhoods's name and address by using an array of structs and file.
my array of structs is
Code:
#define SIZE 30
typedef struct{
char name[30];
char address[100];
}Detail;
Detail neighbor[SIZE];
And I want to make adding,deleting, and searching functions.Something like
Code:
void add();//Add name and address to a file,
//and add more to the same file if I want to.
void del();//Delete or Change some neighbor's name or address
//in the same file(Can I?)
void search();//Search name and show detail
So I started to code adding function first, but I don't know that I need to use pointer to code each functions relations, and I don't know how to check that my input's already exists yet. But I started some code below...
Code:
void add() {
int i=0;
FILE *fp = fopen("neighborhood.txt", "at");

C# :: Fibonacci Series - Adding Value In Array Inside While Loop
May 27, 2014I am making a program to run Fibonacci series. I have created 2 array.
1)- 1st array holds only 0, 1
2)- 2nd array holds other values eg: 1, 2, 3, 5..........etc
I am using while loop to get the febonacci series and storing it in a 2nd array called int[] numbers.
After getting value using while loop, I am joing both the arrays using int[] final = arr.Concat(number).ToArray();
At last, I have used foreach loop to add the febonacci series into the listbox.
The problem I have is that, I cannot able to concat both the arrays. I tried to assign number array at the top of the while loop. so that number variable will be accessible outside the while loop. But I am getting a error.

C :: Filling Array With Even And Odd Number

int a[LEN] = {0} , b[LEN] = {0} , i = 0;

/* OUTPUT :
a[0] = 2 , b[0] = 1

a[2] = 0 , b[2] = 0 */
The problem is some elements of the array would be remained zero and unused. Is there any solution about this wasting of memory?

C++ :: Searching A Number In Int Array?
Oct 12, 2013Basically I initialize an int array of size 10 with zeros. Then element 7 is changed to 1. Via cin I collect a user input (integer) which is the number to be searched.
Now the problem is that the search function from the book is somehow not working. I added a function to see how the array looks like and there is definitely one element with value 1 that should be found, but it simply isn't. The function always returns -1 (element not found).
The program compiles, but doesn't work as it is supposed to.

C++ :: Number Of Sequence In Array?
Apr 24, 2013I am trying to write a program that checks whether the number is in sequence(as in if the numbers are in order it is a sequence). Ex: If the numbers are {1,2,3,6,7,8,9,10,11,13,15,17,20,21}, then, the underlined parts are a sequence. Now i want to find
1) the no of sequence in the array(in the above it is 3 )
2) the longest sequence (7to 11 which is 5).
C++ :: Finding Highest Number In Array

C :: Finding The Biggest Number In Array?
Feb 2, 2014I'm supposed to find the biggest number (largest value), in any given array A with n numbers. (no floats)
My thoughts here are, check if A[0] > A[1]. if yes, check if A[0] > A[2]. If no, check if A[1] > A[2] etc.
I'm not sure how I can do this in code. I'm thinking if A[0] > A[1] is true, then set A[0] = A[k]. Kind of set it aside, and use that for the next if test. But I'm not sure how to do it.
This is my code so far.
Code:
int main(){
int A[7] = {12, 6, 9, 33, 2, 25, 53};
int i, k;
k = 0;
[Code]....
I'm aware of the flaws here, but this is the best I can do so far. How can I get the if test to use A[k] next, as A[k] will always be the biggest value?
