C++ :: Creating Dynamic Arrays / Structures
Feb 7, 2012We are supposed to create a menu with an option to add a car (make, model etc) to inventory. I have the structure format set up as far as adding the car, but I am stuck on how to make it a dynamic array of structures or whatnot (I'm not really sure on what I'm trying to do in the first place!) Basically, the user can choose to add a car and its info in. How do you set up the array to add whatever number of cars is needed? Will it be able to add more cars should the user come back to the program later?
This is the instruction of this portion of the project :
Menu Application
Add a car to inventory
Prompted to add
Make, Model and Year, Color, Miles, Price
Finish (adds the car to the file)
Cancel takes you to the main menu
C++ :: How To Delete Elements In Array Of Structures

View 1 Replies View RelatedVisual C++ :: Implementing Dynamic Database Structures?
Mar 21, 2013We're designing a new software and we want it to be customizable without code. That, for us, mean we can change the software behaviour without re-writing code. All will be developed using C and .NET.
One of our goals is to have what we are calling "dynamic tables". This means that these database tables may have different fields depending on the customization. We got to know it using high-level ERPs like SAP or CRM's system like VTIGER or even SalesForce. Let me give an example:
CUSTOMER TABLE:
FIELDS: ID, NAME, ADDRESS, PHONE.
This would be the standard Customer Table.
Now, a new customer needs to add FINANCE SCORE and RANKING to the database. We them would like to go to our application (not the database itself) and adding these new fields. After that, all of my input forms and reports would start to show and process these new fields.
C++ :: Dynamic Data Structures And Information Input
Feb 17, 2013I want to have input data stored in a database. All information entered is to be stored under a single block. That way whenever I want to recover that information all I have to do is point to that block. Think of it like this. I want a large square block that can hold certain information. Inside of that large block are a finite amount of smaller blocks in which the user entered information about a single subject. Lets say block 1 has a name, address, and phone number. The second block will have the same TYPE of information, but different values as entered by the user. I.E:
BLOCK 1: Name 1, Address 1, Phone 1
BLOCK 2: Name 2, Address 2, Phone 2
etc.
The large block contains all of the smaller blocks, we will name the large block "Address Book" ... How would I implement that? Of course it would be just a simple console program that would erase all information when the program shut down, but I've been trying to figure out how to do it, but just can't seem to grasp a good notion of how to do it. What would be the best way to do that? Structures? How would I make it dynamic so that I wouldn't have to define every block, so that it would be added on the fly when someone inputs new information.
C++ :: Dynamically Changing Array Elements Inside Of Structures?
Feb 1, 2015I have run across what I believe to be a syntax problem which I don't understand. I have a structure with two character array and I need to be able to change the size of those array dynamically. I have to use character arrays and I think the dot notation. I am not sure if I can use arrow notation. I can not do this problem using strings and vectors.

C++ :: Dynamic Arrays - Sort Input Data And Calculate Average
Jul 15, 2014I'm still fairly new to c++ and am having trouble with dynamic arrays. My task is to create an array for test scores. The user needs to define the size of the array and then input data to later sort and calculate the average.
Below is what I have so far. I am struggling with the user input part. I receive the following errors for the data input of the individual scores:
"error C2108:subscript is not of integral type"
"IntelliSense:expression must have integral or unscoped enum type"
Code :
#include<iostream>
#include<iomanip>
using namespace std;

C/C++ :: How To Find Average With For Loop
Sep 14, 2014What i need it to do is ask the user for a number of cases. The user will input numbers and the program should add the inputs until zero or a negative number is entered and then out put the average of those inputs. The amount of cases is pretty much how many times an average will be done. so if the amount of cases is 4. and the inputs are 1,3,(1+3/2)0 then it should output 2. and that would be ONE case, next inputs are 5,6,4,0(5+6+4/3) the output is 5 and that is case two. etc.
Here is my code:
#include <iostream>
using namespace std;
double avgVal(int, int);
int main() {
int amountOfCases;
cin >> amountOfCases;
int* numbers = new int[amountOfCases];
int input=0;

C/C++ :: Swapping Elements In A Struct Dynamic Array
Dec 1, 2014Let's say there is a document which stores data of exams of 3 subject. The document is in the below format:
Subject code [spc] Student code [spc] Exam score [endl]
Repeatedly, there are 100 data. E.g.
ENGL_S12 [spc] 000001 [spc] 90.5
ENGL_S12 [spc] 000005 [spc] 77.3
MATH_G22 [spc] 000502 [spc] 100
LATI_F11 [spc] 002005 [spc] 65.4
...
Now I have to write a function show_exam_descending(Data d, string subCode)
when I call show_exam_descending(d, "ENGL_S12")
the program will execute to show all the students' exam scores in ENGL_S12 in DESCENDING order...
For this to run, I have declared a struct Data:
struct Data {
string subjectCode;
int studentCode;
double examScore;
);
For the search, I have written a function before to load all the data from the document by using pointer and dynamic arrays. It works so well. What troubles me is the way to swap the elements (i.e. examScore) of different students in struct dynamic arrays. I am able to display all of them, but don't know how to swap.
C :: Find Average Of Random Numbers
Aug 17, 2013I have the random values down but when I try to assign randValue to another integer I get an error.I want to make an inner loop where I find 5 random number 50 times and print the average of those numbers.

C++ :: Timing Function - Sort Dynamic Array With N Elements
Apr 11, 2014I'm writing a program that will implement BubbleSort and MergeSort and time them as they sort a dynamic array with N elements. These are the instructions on what my main.cpp file should do.
main.cpp
Include all needed libraries for timing and random number generation while the number of element, N, is less than 100001 repeat the following.
create an array with N (initially 10) random elements
sort the same array with Bubble and Merge sort
time how long it takes each algorithm in microseconds (see example below)
Increase N by a factor of 10 (N *= 10)
Hint: you may want to put your merge sort object on the heap and delete it with every iteration of this loop
And this is what I have so far for my main.cpp
#include <iostream>
#include <sys/time.h>
#include <ctime>
#include <cstdlib>
#include <stack>
#include <iomanip>
#include "BubbleSort.h"
//#include "MergeSort.h"
[Code] .....
One of the errors that I'm running into is that I'm not sure how to correctly call the function I think?

C++ :: Find Average / Highest And Lowest Score?
Oct 9, 2014Create a 1-D Array to hold a set of exam scores:
55 74 93 84 64 72 69 78 87 84 72 33 83 68 62 51 88 90
Write a program to do the following tasks:
1. Display scores in rows of four(4) scores.
2. Calculate average score and display.
3. Find Lowest score and display.
4. Find Highest score and display.
5. Find the deviation of each score, and display the score and its deviation.
6. Find the Standard Deviation and Display
7. How many scores are within One Standard Deviation
So I have the average down, but I am getting stuck at the part of displaying the highest and lowest score. Every time I run the program I get two giant negative numbers for both of them. I put all the scores into a .txt file and I just opened in through the program.
#include "TCHAR.h"
