C++ :: Creating Table Of Arrays - Find Maximum Value And Sum
Aug 12, 2014
I have an array of "2,3,4,5,6,9,10,11,12,99". I need to create a table of this which i have done using case
1. Find the maximum value of the array
2. Find the sum of the first and last element of the array
3. Swap the adjacent pairs of arrays
4. Display the values in array
5. Quit
Please enter choice:
but when i try running the program i did i keep having the break or continue pop up ....
#include <iostream>
using namespace std;
int main() {
int choice;
int number[10] = {2,3,4,5,6,9,10,11,12,99};
[Code] .....

I got a code written in Java. But, I gave up writing code in Java. The program written is supposed to find the maximum subsequence sum. It's originally like this.
Code:
private static int maxSumRec (int [] a, int left, int right)
{
if(left == right)
if(a[left > 0])
return arr[left];
[Code] .....
I turned it into C, add some elements (to generate random numbers and change some variables' names), and becomes like this
Code:
int maxSumRec (val, left, right)
{
int x;
long int arr[val];
srand ( time(NULL) );
for(x=0; x<val; x++)
[Code] .....
It fails to compile. What have I done wrong? And I keep wondering why in the original code there is left and right variables and their values are never assigned. My c compiler (I use codeblocks) keeps telling me that. Idk why. My friend who keeps it in Java says it is fine but he cannot explain how his program works. What *is* left and right actually?

Any way to determine the highest value of an array I created with random numbers. I am confused because the array needs to be initialized in the main, but populated in a function. I was able to populate it using a pointer variable and my results came out good for the initial array values and elements.
In order to figure out the max, I think I would need the results of the populated array. How do I do this when the populated array is stored in a pointer variable? Would I need to create a pointer to the first pointer I created? I tried creating another pointer to the initial array and printing that, but my results were not good.
Code:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>

I'm new to C++ and I'm trying to solve the question but there is just something wrong somewhere.
#include <iostream>
using namespace std;
int main() {
int largest;
int a;
int b;
int c;
cout<< "Enter first value";

Supposing you have a 3 or more overlapping arrays (arrays having elements in common), and you wish to select 2 or more of the arrays with the maximum number of elements but less overlap as compared to the rest of the overlapping arrays.
Eg. A[4],B[6],C[5]. A+B contains 10 elements but say the overlapping element is 3, meaning it has 7 unique element.
Also B+C=11 elements , but supposing it has 5 overlaps, it would mean it has only 6 unique elements. A+B+C=15. Supposing the overlaps are 11 then it means the unique elements are 4. Ect. So per the example, the best array options with most unique element would be A+B .

I was given some practice problems in my programming class, to prepare for the final and I don't quite understand what this one is asking for exactly:
Write the remainder of the program to find the maximum value for the middle row of the array data. Print the max after finding it. Your code should work for any 2D array of ints with three rows and four columns, so don't hard-code your program to these specific values.
Code:
#include <stdio.h>
int main(void)
{
int data[][4] = {{ 5, 8, 7, 2},
{ 3, 10, 1, 9},
{ 6, 12, 5, 0}};

I have problem with finding the maximum value in a column. This is my code
Code:
#include <stdio.h>
#include <stdlib.h>
int main() {
FILE *fp;
fp = fopen ("C:
ocket1.txt", "r");
float time, altitude, velocity, acceleration, amax, bmax;
[Code] ....
The first loop will print out all of numbers in the velocity column. The second while loop is looking for the maximum value in that column. It is supposed to print out the max velocity in the end of the second loop. However, when I build and run the program, it's crashed. I run debugger and received "Segmentation fault" error. When I eliminate the second loop, it run just fine I use Code::Block for text editor.

I'm unable to get the grades to print in the table format, it only takes the homework grades and not the tests and quizes.
// week 8.cpp : Defines the entry point for the console application.
// Gradebook 1.cpp :
/*Rewrite the program "Gradebook 1" to contain 1-dimensional arrays. All information entered or calculated within the program is located in an array. The final output(Class Summary) should contain a summary sheet that contains all of the information in table form. */
#include "stdafx.h"
#include <stdio.h>
#define Size 30//Maximum class size
#define max 100//maximum grade
#define min 0//minimum grade
[Code] .....
This is my result :

Having trouble with homework involving (title). Here is the assignment:Write a program that allows the user to enter 10 numbers from the keyboard. Sort the numbers using any sort routine you wish. The output from your program should be 2 columns of numbers. The left column should be the numbers in the order they were originally entered and the right column should be the sorted list. The columns should be labeled. You will need 2 arrays to accomplish this.
Use separate functions for input, sorting, and printing.So, I have to use separate functions for each of these. I would think it would be easiest to do the input in Main() and then the sorting and printing in another function, but of course since you can't return arrays I am kind of stuck on how I return the new array after sorting. I thought about doing the sorting in Main(), but then I would need to still do the original arrays input in a function and would still run into the same problem.
Here is what I have so far:
Code:
//Cameron Taylor
#include <stdio.h>
#define MAXARRAY 10
int highLow(int[], int);
int print(int[], int[], int);
int main (){
int unsorted[MAXARRAY], i, j, temp;
[Code]...
I know it seems simplistic right now, but I am just trying to get it to work first and then go back and beautify it up a bit.

This program to find the multiplication table, need explanation this step : printf("%d * %d =%d ", n, i, n*i);
#include <stdio.h>
int main() {
int n, i;
printf("Enter an integer to find multiplication table: ");
scanf("%d",&n);
for(i=1;i<=10;++i) {
printf("%d * %d =%d ", n, i, n*i);
} return 0;

How do you prompt the user to enter the number of elements for the array and use that information to creatr a variable length array? And then how do you prompt the user to enter in a number for each element of the array and scan in the appropriate numbers? the numbers are double precision floating point.
for example,
Enter the numbe of elements in the array: 3
Enter element 0: 3
Enter element 1: -1
Enter element 2: 4
I know it starts with
int main() {
double N;
int a[size];
printf("Enter the number of elements in the array:" );
scanf("%f", &size);
//I'm pretty sure this is wrong

I'm working on a project where I have the user enter storm data about hurricanes for multiple seasons. I need to make separate arrays for:
1. the month, wind speed, and min. press.
2. the category of the storm
What I'm having trouble understanding is how to make the software take an input, assuming from a scanf, and put it in an array. Then taking that value and output-ing it back out when needed.
So here is piece of my code. Note: Disregard the commented sections of the code, my current project is building off a previous one, where in the last project we were using loops, now we are using arrays.
case 1:
{
if (year > 0) //begins counting
{
/*num_trop_storms = 0*/ num_hurricanes = 0, year = 0, wind_speed = 0,
hcat1 = 0, hcat2 = 0, hcat3 = 0, hcat4 = 0, hcat5 = 0, hrun = 1, totalhurr = 0;
knots = 0, cummwindspeed = 0.0;
[Code] ....
In the code above, how exactly the scanf takes the inputs from the user and then stores them for me to access. So, I want my array to be 3 columns, for months , wind_speed, & minpress. The array has a undetermined amount of rows. I think if I figure out the first array, I can handle the second.

We 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

I receive unexpected outcome in my program. Instead of getting all combinations of 0, 1, 2 (i.e. 000, 001, ..., 222) I get only 000 001 002 010 011 012. The idea of the progarm is to create a crystal lattice. Each atom of the lattice has 3 coordinates (x, y, z). That's why I create class Atom. Then I create 3-dim array of the type derived from class Atom. Now each element of the class will represent an atom.
Code:
#include <iostream>
using namespace std;
class Atom {
public:
float x, y, z;

I'm supposed to create a "game" that is similar to Candy Crush or Bejeweled. The assignment takes in a .txt file that contains a matrix of values from 1-5 and then assigns each value to a spot in a [10][10] array. Then an Escape Code function prints out colored pixels in place of the number values for each spot, creating a "game board" looking output. Finally, the program is supposed to look for any matches of 3 same-colored pixels and replace them with a white pixel and "XX". Then the program prints the corrected game board with the matches X'd out.
I have it mostly coded, but I've encountered a couple of issues.
1.) I am supposed to label the columns and rows 0-9, and while I have no problem coding the labels for the columns using printf( ), when I try to print the row labels I get a random string of numbers.
2.) I replaced the matches with white pixels by reassigning the value in the array to 7, for which the ANSI Escape Code is white. However, I'm unsure about how to print the "XX" in the same spot.
Here is the input(.txt) file and the output of the program so far:
And here is what I have coded at this point:
Code:
#include <stdio.h>
void printEscapeCode(int c);
int main(void)
{
/* Declare an image array to be gameboard */
int gameboard[10][10];
/* Declare variables and load in how many rows and columns */
int Nrows;
Nrows = 0;

This program does everything i want except for one major problem and one small one.
1. The program keeps taking my last entered number and counting it as max and min
2. When I go to end with 0 it adsd the enter number prompt then returns.
#include <iostream>
using namespace std;
int main()
{

I wanted to write a program that will determine a set of values that add up to a target value. I want to use 12 bins and fill the bins with random numbers between 0 and 20. Then, look for a target value of 30.
Here is what I have so far. (mix of actual code and Pseudocode.)
#include <stdio.h>
#include <string.h>
#include <ctype.h>
#include <conio.h>
#include <stdlib.h>
int main (void) {
// columns: 0=value 1=checked 2=selected

So first I have to display a 2D array with all 0s, which is pretty easy.
#include <iostream>
using namespace std;
int main (){
int array[5][5];
for(int a=0; a<5; a++){
for(int b=0; b<5; b++){
array[a][b] = 0;
[Code] ....
So this displays
0 0 0 0 0
0 0 0 0 0
0 0 0 0 0
0 0 0 0 0
0 0 0 0 0
Next, this is where it gets confusing. I have to create a virtual creature by storing a letter into a random position in the array (the array can be up to 20x20 in size). Then make a function that searches the array for creatures, so it would search for that character. When it finds a creature, it should randomly decide to either move the creature to an adjacent position, or have it stay where it is. After, it should ask the user to create a new creature, or quit.
So how would I go about adding & modifying the current code to achieve what is listed above?

I am having an issue with my sort function. This is one part of the Hash table program. The main issue is that I am trying to sort the pointer table after all of the values have been entered. The ptr_sort function is not a class function and so I am therefore unable to use the class variables psize and pTable. Is there another way I should be trying this? it is a Vector should I use the sort() function from the vector class in STL?
#include "/home/onyuksel/courses/340/progs/13f/p9/util9.h"
#include "/home/onyuksel/courses/340/progs/13f/p9/hTable.h"
#ifndef H_TABLE1
#define H_TABLE1
void ptr_sort ( );

If a user enters a string of boolean algebra it will ouput the table.
I have input parsing, cycling through the combinations, and outputing working. However once i parse the input I am not sure what to do with it. I have thought of having it write the parsed input to a new file as a function and then use that function, but that seems bad.
How to dynamically create the function, how to implement it.
BTW This is a console function, if that changes anything.
