C :: Access Element Of Array Through A Pointer To A Pointer

C++ :: How To Access Element Of Point3f Vector
Aug 4, 2013How to access an element of the point3f vector. E.g. :
int main() {
vector<Point3f> a;
a.push_back(Point3f(0,0,0);
a.push_back(Point3f(0,0,1);
//print first x,y,z element
cout<<a[0]<<endl;

But it doesn't work firstly because it says can't use typename i.e. <float>

Jan 22, 2015I need to know how to access the nested structure using pointer, i mean i know how to do that when i have simple structure, for example:
Code:
struct person{
char fname[16], lname[16];
int age;
}
for this example i can use
Code: (*pointer).age
or
Code: pointer->age
But if i have structure like this:
Code:
struct date{
int day, month, year;
}
struct person{
char fname[16], lname[16];
struct date birthDate;
}
Then how can i access the birthDate using pointer?
C++ :: Composition And Member Access Inside Composed Structure
Jan 18, 2013I have a question regarding composition and accessing members "deep" inside the composed structure. For example;
class A {
private:
int m_myInt;
public:
int myInt() const {return this->m_myInt;};
void myInt(int newInt) {this->m_myInt = newInt;};
[Code] ....
Now, from somwhere I have access to an object of type B where I want to update the A::m_myInt. How would you do this without "breaking" the whole purpose of private/public members?
B myB;
myB.m_a.myInt(3); // Not allowed, and not desireable
I thought about implementing access through functons kind of like;
A & B::a() {return this->m_a;};
myB.a().myInt(3);
but I'm worried that this exposes my B::m_a-object too much. This would allow
myB.a() = A();
, right?
The following is a more desireable way of acces, but doesn't work for updating;
A const & B::a() {return this->m_a;};
myB.a().myInt(3); //Disallowed? myInt(int) is non-const.
What about this? Is this a good way of doing it?
class A {
private:
int m_myInt;
public:
int myInt() const {return this->m_myInt;};
[Code] ....
I guess it works? It would lead to a lot of data shuffling in case of larger sub-components.I would really like to do the following without exposing my components so much:
B myB;
myB.a().myInt(3);
Can it be done?

C++ :: Only The Last Element Of Array Works
Oct 5, 2014My 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];

C++ :: How To Delete Element From Array
Jan 9, 2015how 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.

C++ :: Pointer To Array Element?
May 13, 2013How 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
C/C++ :: Finding Element Of Array
Feb 17, 2014"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" .
EXAMPLE
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.
I am working on it for 2 weeks and I can't find a working solution />/>/>

C/C++ :: Finding Middle Element Of Array?
Mar 12, 2014Above you said to find the middle value you should divide the array by two and then display the middle value (aka the median). For example, for an array consisting of 1 2 3 4 5, 3 would be the middle value.
My question is, how/what do I write to tell the program to display the middle value???
So far, I have done enough research and written enough code to receive values from the user and sort the array in ascending order. I simply don't know where to go from here (I started C++ about 1 month ago). I don't know how to tell it to pull the middle value.
I've researched "find_if", "nth_value" and a boat load of others with no luck
Here's what I've done so far:
#include <algorithm>
#include <functional>
#include <array>
#include <iostream>

C/C++ :: How To Avoid Replacing Element In Array
Oct 6, 2014I am working on a parking lot scenario project using multidimensional arrays. The parking lot has 8 rows and 10 parking spaces in each row. Altogether there are suppose to be 30 cars parking in the lot and arrive in numerical order. I am suppose to generate a random number to represent the row and another to represent the space in the row.
The problem I have is that a few of the elements are being replaced. The project requires the car to check if the space is taken, if so it is to find another one. Here is what I have...
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#define ROW 8
#define COL 10
#define CARS 30
void parkTheCars(int result[ROW][COL]);
void displayArray (int result[ROW][COL]);
