C++ :: Value Of Array Is Not Copied To Other Array

Oct 22, 2013

I'm trying to copy one element value in an array to other array(Line no: 19) in the following program.

There is some problem due to which it is displaying ZERO.

Need to fix the Problem in this function member.

int tdms (int m, float* x,float* y,float* z, float* w, float* u,float tt,float ddt ){
for(int k=1; k<=2;k++) {
cout<<"
Time step: "<<ddt*k<<"

Visual C++ :: Being Argument Array Not Copied When Calling Function

Feb 7, 2013

The code below outputs this:
a[]= 00
a[]= 10
a[]= 10
a[]= 10
a[]= 11
a[]= 11
0.

But I was expecting this:
a[]= 00
a[]= 10
a[]= 10
a[]= 00
a[]= 01
0.

This describes how the process is running in machine:
1. Defining a[2]{0,0}; ii=0; aj=0
2. Calling function func(a,ii,aj) |func({0,0},0,0)|
3. func({0,0},0,0) defining w=0; static aa=0
4. func({0,0},0,0) if(0) returns aa=1
5. func({0,0},0,0) for j=0
6. func({0,0},0,0) for Outputing "00", because a[2]={0,0}, look (1).
7. func({0,0},0,0) for if(!0) | because a[0]=0| returns w+=func(a,ii+1,j) |func({0,0},0+1,0)| and calls func({0,0},1,0)
8. func({0,0},0,0) for if func({0,0},1,0) defining w=0
9. func({0,0},0,0) for if func({1,0},1,0) if(1) returns a[0]=1, because of static aa=1, см 4.
10. func({0,0},0,0) for if func({1,0},1,0) for j=0
11. func({0,0},0,0) for if func({1,0},1,0) for Outputing "10", because of a[2]={1,0}, look row #9
12. func({0,0},0,0) for if func({1,0},1,0) for if(!1) |because a[0]=1|
13. func({0,0},0,0) for if func({1,0},1,0) for j=1
14. func({0,0},0,0) for if func({1,0},1,0) for Outputing "10"
15. func({0,0},0,0) for if func({1,0},1,0) for if(!0) |because a[1]=0|
16. func({0,0},0,0) for if func({1,0},1,0) for if if(1==1) |because ii=1, func({0,0},ii,0)|
17. func({0,0},0,0) for if func({1,0},1,0) for if if return 0
18. func({0,0},0,0) for if w=0 |because func({1,0},1,0) gives 0|
19. func({0,0},0,0) for j=1

And from now, something is happening that I cannot understand:
20. func({0,0},0,0) for Outputing "10"

Why so? If func has itselfs local variables, including a[2]={0,0}.

I was expecting this:
20. func({0,0},0,0) for Outputing "00"

So a[2] array is not local variable. Why it happens?

Code:
#include <iostream>
using namespace std;
int func(bool a[],int ii,int aj) {
int w=0;
static bool aa=0;

C++ :: Code Won't Compile Even If Exactly Copied From EBook

Mar 23, 2013

I recently downloaded the ' code:blocks ' file. After I tried some code the compiler stated there was an error with
' #include<iostream> '.

Since I'm not a C++ programmer, right now, I'm confused. This was copied directly from the e-book I downloaded. After I uninstalled this program, I re downloaded it and now it comes up with a new error while opening Code-blocks.

This new error states ' Can't find compiler executable in your configured search path's for GNU GCC compiler '

C :: Counting Number Of Characters Copied To File

Jul 21, 2014

I'm trying to copy a file into another file and copy the number of characters copied but my while loop doesn't even enter into a loop indicating the file is already at the EOF file character. I've confirmed this by placing the printf() statement inside the while loop, which doesn't print anything and by keeping it out of the while loop and changing the chars_copied to something like 9, it prints 9 for number of chars_copied. I don't understand why the file is already at the EOF character, I've tried this with a few more files, it's the same result.

Code:
#include <stdio.h>
int main(void){
FILE *input_file, *output_file;
int c, chars_copied=0;

if((input_file=fopen("C:workmarks.txt", "r"))==NULL)
perror("input file open failed");

C++ :: Create Array Of Playing Cards / Assign Values And Suits Then Shuffle The Array

Nov 24, 2014

I got this program to create an array of playing cards and assign the values and suits and shuffle the array. I'm at the point where I need to output the cards but I need to burn the first card by making it output "**" instead of the card. my cards[] is a constant so I can's assign the first card as such.

void showCards(const int cards[], int numCards, bool hideFirstCard) {
if (cards[0]) {
hideFirstCard=true;
cards[0] = '**';
} for(int a = 0; a <= numCards; a++) {
cout >> showCard(cards[a]);
} }

C :: Store Character Array In Reverse Order Then Display Reversed Array

Jun 14, 2013

The program should store a character array in reverse order then display the reversed array. I have also included in the code that will display the actual characters into the array as it loops through. So I know the characters are being stored, but why doesn't it display the entire string when I call it?

Code:
#include<stdio.h>
int main(){
char str[50];
char rev[50];
printf("Enter Desired Text: ");
scanf ("%[^

C :: Parsing Char Array To Array Of Struct To Process Packets

May 28, 2013

I wrote this simplified version of a program i am writing that parses data in UDP packets. In the process of doing so i pretty much answered all my questions and fix all the problems i was having.

decodeSystemMap function will be in loop, and will proccess packets that have mostly the same data, only a few items will be added or changed or deleted.

whats the best way to check if there are any new, deleted, or removed items in the packet and only modify those?
Is there anything unsafe / dangrous about the way the code is now?

Code:
/* * File: main.c
* Author: david

#include <stdio.h>
#include <stdlib.h>

C :: How To Make A Function Read From Array A But Put Select Parts In Array B

Jul 30, 2013

im trying to read in 1 array and get 2 as outputs from 3 different functions.my read array is easy enough were im getting confused is how to read that array, separate it and take out only the parts i want and place them into a 2nd, then again a 3rd array.i have the following so far:

Code:

#include<stdlib.h>#include<stdio.h>
#include<unistd.h>
#define SIZE 10
}

[code]....

this compiles without a complaint, but when i go to run it no longer responds after taking the 10th element (well 9th if counting from 0).I think i have the if correct for the even odd section, but when i try to populate B or C array with the output of that if statement from A is were i think things are dying...

C++ :: Using Loop To Process Array Of Characters Starting From Beginning Of Array?

May 3, 2014

Assume you want to use a loop to process an array of characters starting from the beginning of the array. You want the loop to stop when you read the null terminator character from the array. Fill in the loop test condition that will make this work correctly.

index = 0;
ch = array[index];
while ( _____________________________)
{
// process the character
index++;
ch = array[index];
}

C++ :: Multidimensional Array - Moving Whole Int Array Row As A Single Unit?

Feb 27, 2013

I have a multidimensional array that runs parallel with a string array

Lincoln 120 300 400
Parks 100 500 250
Shakespeare 0 30 50
Ghandi 250 100 40
Ashe 300 50 175
Rodriguez 87 118 320
Curie 284 0 112

I need to sort this and I know how to do it. But I need to sort it again with the highest value in the first row and keep all information in that row paired with the name . So

Lincoln 120 300 400
Parks 100 500 250

Parks 100 500 250
Lincoln 120 300 400

I need so swap this whole rows. I'm using dynamic array. So my question is Do I have to do a bunch of temps to move them? Or is there a way to move the whole int array row as a single unit?

The second statement works and i'm able to print out both arrays with equal values but with the first

C :: Print Values Of Array From Function By Passing Array?

Nov 1, 2014

I wanted to print the values of a array from a function by passing the array as well as the number of elements to be read. For a single dimensional array, this is how i have written it. It's pretty straight forward. I want to read 5 elements from the 5th element in the array.

Code:
#include<stdio.h>
void display(int array[],int size) {
int i;

[Code]....

With this code I want to print the five elements from the element present in [0][4].

But shows an error that

Code:
D:BennetCodeblocks CLearning CSingleDimentionalArray.c||In function 'main':|
D:BennetCodeblocks CLearning CSingleDimentionalArray.c|18|warning: passing argument 1 of 'display' from incompatible pointer type [enabled by default]|
D:BennetCodeblocks CLearning CSingleDimentionalArray.c|2|note: expected 'int (*)[10]' but argument is of type 'int *'|
||=== Build finished: 0 error(s), 1 warning(s) (0 minute(s), 0 second(s)) ===|

I know when you pass a array as an argument it gets decomposed into a pointer, but with a multi-dimensional array this is not the case. how this works for mult- dimensional array's?

C++ :: Passing 2D Array To A Function Where Size Of Array Is Not Known At Runtime

Jun 27, 2014

I'm wondering if it is possible to pass a 2d array to a function where the size of the array is not known at runtime.

I've tried

function ( array[][6] ) ;

But the size of the array has to be constant so it cannot be declared later.

I've tried using a template but you still have to declare the size of the array at runtime. Is this even possible at all?

The only other way I can think of is using a dynamic 2d array but how to create one and manipulate it.

C++ :: Allocating Array Of Pointers To Dynamically Allocated Array?

Jan 18, 2014

I'm trying extremely hard to understand pointers and I have the basic concept down.. I feel as though my knowledge of dynamically allocated pointers and pointers in general is not enough to understand the logic behind what I'm trying to do. The problem is that the donations array must be able to accept any number of donations. I've made it do just that, but there is also an array of pointers which must each point to the same element in the donations array. The program works if I assign int *arrPtr[100] for example, but it does not work if I try to dynamically allocate it to accept the same number of elements for donations entered by the user. Here it's the snippet

#include <iostream>
using namespace std;
