C++ :: Using Array Of Integers In Classes
Feb 28, 2013
How to solve this because i was not able to get the idea of using arrays in classes . Here is the Question :
The PVR Cinemas manager approaches you to develop a system for ticket booking. It has 5 screens each with a capacity of 500 seats of which 100 are platinum, 100 are diamond and 300 are gold. The cost of platinum, diamond and gold tickets are Rs.150, Rs.125, and Rs.100 respectively.
•Construct a class to model a screen with an array of integers for each category of seats. Provide a constructor to initialize the array to 0.
•Include a member function bookSeat() that gets the category of the seat and number of tickets to be booked and then prints the seat numbers. The booked seats are marked by 1. If no seats are available then your program should display appropriate message.
Test the above class with a main program that creates an array of objects (size of array depends on the number of screens) and display the total amount to be paid by the visitor.

I have 2 integers, both in 2 seperate classes in 2 seperate files. I have main.cpp, test_01.h, Test_01.cpp, Player.h and Player.cpp. I ahve a function which takes an integer (a) as a parameter (from Test_01.h and Test_01.cpp). a sets another integer (attackPower) from the same class equal to a. The integer (health) in the other class (Player.h and Player.cpp), is then equal to health -= attackPower. But instead of giving me the right answer 75 (health = 100 and a is set to 25 when i call the function) it gives me the answer.
main.cpp
#include <iostream>
#include "Test_01.h"
#include "Player.h"
using namespace std;
int main() {
Player p;
Test_01 t;

I have a base class Building. Then come its children classes - Commercial Building and Residential Building. The third level is composed of Apartment and House classes, both inherit from Residential Building.
I need to create an array of 20 elements that will store info about all these different types of buildings(Commercial Building,Residential Building,Apartment, House). How should I proceed?

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

I now know how to count integers with while loop but I'm not sure how to count the integers with array.
So the question is:
1. program should keep reading integers as long as the integers are within [0,9999]
2. when user typed the integer not between 0 to 9999, the program print out the numbers of integers that were typed.
Sample
3
3
3
9999
9999
-1
You entered 3 3 times.
You entered 9999 2 times.
#include <iostream>
using namespace std;
int main() {
int i=-1;
int x;
int numbers[10000];
[Code] ....
I cannot use "do" ....

I am creating a program and am having trouble with one part. The input file looks like:
Code:
2
3
Bill Jeff Steve
Linda Brittany Jessica
3 1 4
2 1 9
8 3 7
6 4 9
4 8 9
6 9 4
Where I am stuck is putting the numbers into the string array. For example, Bill's scores should be set up as Bill's scores should be set as
Code: bill_score = {3, 1, 4}
and when this code is ran
Code:
for (i=0; i<3; i++) {
printf("%s - ", men[i]);

I am trying to find a way to do something like this:
input: 3 4 7 4 3 3 7
output: 3 4 7
So what I am trying to do is from an array of integers to take numbers that occur only once. If 3 is in that away I am trying to input it in a different array only once.
input: 8 3 2 9 8 9 2
output: 2 3 8 9
I cannot find a way to solve this, and I have been trying to solve it for a long time.

For my code, I want the user to enter 4 integers, which get stored in an array. Here are the lines I wrote relevant to this part:
Code:
printf("Enter 4 integers:
");
scanf("%d %d %d %d," &a, &b, &c, &d);
z[4] = { a, b, c, d};
Would this be correct?

Suppose I wished to initialize a dynamically allocated array of integers to zero. Would I do better to use calloc() or malloc + iterate over all entries setting each to zero? Which one is regarded as a better approach?

I know strings are essentially just arrays of characters, so what would be the easiest way to take each individual digit and put it into a separate space in an array?
ex.) *str = "90210"
array[0] = 9
array[1] = 0
array[2] = 2
array[3] = 1
array[4] = 0
All my attempts at achieving this just result in an array full of garbage numbers. What I've done is
Code:
int *array;
array = malloc(sizeof(int)*(strlen(str));
for(i=0; i<strlen(str); i++) {
array[i] = str[i]
}
also, I should mention that the string will be defined in main, and its converted into an array in a separate function.

how assignments is to write code that returns a value that is repeated more than once in an array of 8 integers.For example:
Numbers: 30 12 100 33 2 2 1 40
Output: 2
Here is my code so far:
Code:
#include <stdio.h
int main(void){
int i;
int j;
int arr[8];
int count;
int maxCount = 0;
int maxValue = 0;
[code]....
When I compile this code (on Vim), I get an error when I print the array of 8 above (see ERROR above).

I'm writing a program that calculates the mode, mean and median of an array of integers. I've done the mean and median but i can't figure out mode.
I have to find the number of modes.
Ex array of integers: 10, 10, 4, 5, 6,5, 6, 7
My function has to return the number 3. Because there are 3 sets of mode; 10,5,6.
How do i implement this in my function because for now it just calculates the mode. It only return the number mode 10.

I am new to programming all together but i have been writing a program in c++ and im coming up against an issue with my array.
#include<iostream>
#include<iomanip>
#include<string>
using namespace
int main () {
int a ;
int b ;
char answer ('Y') ;
[Code] ....
I am trying to get the program to increase say year one by 1 when the condition is met i have tried
if ( a >= 70 && a <= 100 && b == 1)
{grade [0][0] = 0 + 1;}
and
for (grade[0][0] = 0 ; a >= 70 && a <= 100 && b == 1 ; grade [0][0]++)
{grade [0][0]= 0 + 1 ;}
Now all that i want is that the array will take the information from int a and int b and then add 1 to the appropriate part of the array . I have tried putting it in deferent places but its not working for ether. the program will run but it will not add to the array.

Using two-dimensional arrays, write a program which multiplies an mxn matrix of integers by an nxr
matrix of integers.
INPUT FIRST (2x2) MATRIX:
Type in 2 values for row 1 separated by spaces: 3 4
Type in 2 values for row 2 separated by spaces: 5 7
INPUT SECOND (2x2) MATRIX:
Type in 2 values for row 1 separated by spaces: 1 1
Type in 2 values for row 2 separated by spaces: 2 2
3 4
5 7
TIMES
1 1
2 2
EQUALS

My main issue is that when I store just one value into a simple integer variable, it gives me a big negative number.
My goal is to store a file that reads like this into arrays:
2014 1 23
2012 2 15
2013 1 25
etc
Where I would have the first column in an array, the second in another and the third in third array since I am not allowed to use multidimensional.

I'm a beginner at c++ and I need to write a program that reads a set of integers and then finds and prints the sum of the even and odd integers. The program cannot tell the user how many integers to enter. I need to have separate totals for the even and odd numbers. what would I need to use so that I can read whatever number of values the user inputs and get the sum of even and odd?

Write a program that asks the user to type 10 integers of an array. The program will then display either "the array is growing", "the array is decreasing", "the array is constant", or "the array is growing and decreasing."
(Hint: compare consecutive numbers in array and check whether it is increasing or not or constant) I wrote the program very well, but do I have to use "bool" like in c++ ? I haven't known how to code in c++ yet.So, I don't want to use "bool" in C.
I also wrote code about it but it looks like backslash and one,two,three,four,five how can I do it like this ?

what I need is to get the first integer from a file and assign it to a variable and the others integers to an array. Example: Thats my file content 5 4 6 7 8 0 and that would be the code:
Code:
struct Array{
int n;
int *v;
}
