I want to rearrange the positions of structure elements on the bases of perm_array.
Code:
typedef struct gg{
element d;
int group;
} gg;
gg col_data[16];

How can i rearrange structure element like {ptr+2,ptr+3,ptr+1,ptr+0} ?
I was trying to apply what is here (as someone who writes rarely and has to relearn everything each time): [URL] ....
I'm using a header file to define the structure:
#ifndef EINSTEIN_H
#define EINSTEIN_H
#include <stdio.h>
#include <vector>
struct SizeAll{
double year;
double R;
SizeAll() { year = 0; R = 0; }
[Code] ...
This creates quite a mess. It seems that somehow the "vector" declaration isn't working as the referenced web link seems to suggest that it should. I presume that, as usual, clearing one real error will eliminate the cascade of errors the first real error produces. Why won't VC++ accept the "vector" identifier?
The error messages that follow the build attempt are:

this program is not running why can't i access elements in this way directly.
I have a fundamental question due to my lack of understanding how arrays work.Let say I have a character array (byte array).
1. do array elements have memory adresses? i guess not but ....
2. if yes is it possible to switch two array positions? For examle:
a[x] change with a[y] for x,y < |a|
as oppose to changing values assigned to individual array positions.

View 1 Replies View RelatedFor an assignment I have to create a random array of four integers, and then I have to allow someone to input up to ten guesses to guess the array in the correct order. I also need to be able to display whatever was generated by inputting -1. Finally, after every guess I have to tell the inputter how many of the guessed integers are correct and in the correct position, as well as how many integers are correct but not in the correct position.
So far I've been able to get the random array to generate properly, but inputting negative one has no effect, although if I input it four times in a row I get to my 'lose' condition. Also, it only seems to allow the user to input 4 guesses and not 10 before going straight to the 'lose' condition. I need to get these issues sorted out before I can move on to showing how many guesses are right etc....

I am trying to create a code to sort an array of integer, but only between two positions of the array, not the all array.
like this:
array: 1 2 5 4 7 2 9 8
index: 0 1 2 3 4 5 6 7
i want to sort the array per exemple between the the index 2 and 5.the result is... array: 1 2 2 4 5 7 9 8
how to rearrange lists in an special manner.
I have heard about the hashset but I do not fully understand how that thing works or if it is the best option for this issue.
Basically I have 3 lists: LIST1, LIST2 and LIST3.
LIST1 is a set of xyz points and LIST2 shows how the points are connected (clockwise, counter clockwise, coolinear).
For example the fact that in the first line of LIST2 appears 0, 1, 2,-1 means that the points in LIST1 are connected as follows:
(0 0 128.588459085565)->(25 0 134.979628462965)->(0 0 134.979628462965)
Same for line2 of LIST2: 1, 4, 2,-1
(25 0 134.979628462965)->(25 0 140.100717207301)->(0 0 134.979628462965)
etc...
The value -1 at the end of each line does not mean anything but I need to keep it.
Finally LIST3 tells me if the points are connected counterclockwise (-1), clockwise (1), or coolinear (0).
The thing is that I want to get things as follows:
If the values of list 3=1 then I need to extract all the points in the list 1 that correspond to the value 1 in order. However the values in LIST2 cannot keep being 1, 4, 2,-1 they need to be reorganised starting by zero. Expected result in LIST2= 0,3,1,-1.
We need to do this for each value in list3 (1,-1 and 0).
The idea is to get 3 groups of values:
- Group 1 including all the values that are clockwise (list3) with the points in order in list1 and showing connections starting from zero on in list2.
- Group 2 including all the values that are counterclockwise (list3) with the points in order in list1 and showing connections starting from zero on in list2.
- Group 3 including all the values that are coolinear (list3) with the points in order in list1 and showing connections starting from zero on in list2.
The idea is to be able to print 3 files in the following way:
FILE1:
Points which are clockwise in LIST 1
...
Connections of those points in LIST 2
...
FILE2:
Points which are counterclockwise in LIST 1

I have to rearrange my controls in a controlbar based on the new size resulting from dock/undocking of the bars or resizing of the mainframe.
Is there a message I can use? How to determine the new height when docked?
I tried to use its OnSize-function. The problem with it is to get the new height. When the function is called, the height I get from GetWindowRect is the old height.
Is there a better function than OnSize() ?

I wrote a program to find the minimum and the maximum values from a vector. It works fine. What I'm trying to do is show the positions of said values and it's not working quite right. When I insert 4 elements: 2 0 1 3 it says:
"The min and max are 0 and 3
The position of the min is: 01
The position of the max is: 03"

Question: Write a program that calculates sum of the numbers in the given positions.
Input specification : There will be 4 lines of data. You will be first given the size of the positions array (n). Then, the following line will have n integers which is an ordered list in increasing order and 0 < n ≤ 3000. The third line will give the size of the number array (m) where 0 < m ≤ 5000 and The last line will have m integers between -30000 and 30000.
Note: The positions start from 1 and goes until m.
Output specification : Show one integer number. Sum of the Numbers in the given Positions.
Sample Input I
5
2 5 7 9 10
10
1 8 7 5 17 15 6 7 19 12
Sample Output I

My code has been acting odd. I made a function that layers my art resources but only the last tile of my art resource acts the way it should. My character goes behind and in front of the last tile and gets printed correctly. Strangely its really exclusive to the last tiles I print. What I need is to figure out in step by step order what going on with my code sample below and be able to layer the resources.
Here is a small sample of my main function. This is how I do my rendering.
Code:
Int main (int arc, char* args[]) {
//Move class
Move character;
//Class Tile & Side Tile
Tile *tiles [TOTAL_TILES];

how to delete an element(s) from an array; suppose I have an array x[10] = {1,2,3,4,5,6,7,8,9,10}, and I want to delete array{5} so that the values of the array become {1,2,3,4,5,7,8,9,10}; how do I go about this? This is not the same as setting the value of array{5} to null; but completely eliminating it so that it does not get printed alongside the other elements of the screen.

How would I go about having a pointer to an array element specificity a character in a c-string.Every thing I try will not even build.An array is already a pointer to the first location of the array right?
char *pHead;

pHead = sentence[0]; <=== This wont build
pHead = &sentence[0];
pHead = sentence[0]*;
*pHead = sentence[0]; <===== this builds but is not storing anything
"Write a program in C that finds the element of an array which all the previous are smaller and all the next are bigger than that.If there are more than one print the biggest. If there isn't any print "ERROR" .

If the array has 10 elements like this : {2,3,4,6,5,7,8,10,9,8}
The correct answer is 7 , because 2,3,4,6,5 are smaller than 7 and 8,10,9,8 are bigger than 7.
