C++ :: Tic Tac Toe Program Using Arrays
Mar 1, 2012
how to write a basic tic tac toe program using arrays. I've already done one but without using arrays. As you can see in the code below, there is too much repetitive code which I don't like the look of.
As a beginner, I would like to attempt this myself. I just need to know where to start, what to do, etc... This is where I am stuck.
Here's my code for the tic tac toe program:
Code:
#include <iostream>
using namespace std;
int main()
[Code].....

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()
{

Add a program that declares two arrays of 5 integers each. Provide one function to load one array with random numbers from 1 to 25, another to fill the other array with user supplied values, and a third function to print an array. The main function should declare the arrays and use the functions to fill each array and print them both.
The code i have so far is
#include <cstdlib>
#include <iostream>
using namespace std;
void printaaray(int printarray1[], int printarray2);
[Code]....

Been working on this program for a while. It's currently broken in several parts but it at least reads and stores the data into the arrays correctly. The problem is writing the sort function and the swap function. The other problem is writing both of these to keep the correct ages with the correct names.
/*
Write a program to allow the user to enter up to ten people with their age.
The names will be a full name consisting of a last, possibly a middle initial, and a first name.
The full name will be no longer than 40 characters in length.
The full will be stored in an array of strings, a two dimensioned array of characters.
The ages will be stored in an array of integers. Manage the arrays as parallel arrays.
Data entry will be from the keyboard and will read the full name followed by the age.
Data entry will terminate when the arrays are full or when nothing is entered for the full name.
Use a subroutine to enter the data and pass the arrays to the subroutine, do not use global arrays.
Once the data is completely entered, use another subroutine to print out the arrays to the screen.
Then use a subroutine to sort the data on the full names, ascending order.
Reuse the print subroutine and print the sorted data out to the screen.
Write another subroutine which sorts the data on age as the primary sort and full name as the secondary sort.
Finally reuse the print subroutine to print the data to the screen.
The main program will call the data entry function, followed by the print function, the name sort function, the print
function, the age sort function and finally the print function.
All data will be passed to the functions, no global data.
*/
#include <stdio.h>
#include <string.h>
#include <stdio.h>
#define SIZE 5
void input(char fullname[][25], int age[]);
void output(char fullname[][25], int age[]);

I wrote this program using struct and it works fine, now I want to write it just using arrays and I don't think i can do it. So here is the original code:
#include <iostream>
#include <string>
#include <fstream>
#include <ctime>
#include <cstdlib>
using namespace std;
//function declarations
void init()

My tasks was to write a program which finds difference between two arrays (elements which are in first array but not in second and vice-versa). Program works, but something wrong is with the memory allocation for array.
My code is:
main.c Code: #include <stdio.h>
#include <stdlib.h>
#include "header.h"

writing this program where you can search a structure array for existing elements, add new elements to the structure array, and find and display entire elements of the array structure and all.
Right now I am stuck on adding new elements to the structure array.
#include <iostream>
#include <string>
#include <iomanip>
[Code]....
Any methods to displaying the a array structure or editing it ....

Write a program that prompts for and reads in test scores. You may assume that valid test scores will be integer values between 0 and 100. You may also assume that the user will not enter more than 35 test scores. Use a preprocessor directive to define this value. User input will be complete when the user enters a -1 for the test score. When all of the test scores have been entered, the program will print out the scores. Use a while or do-while loop to read in the values. Use a for loop to print out the values.
Sample output:
Enter test score 1: 88
Enter test score 2: 67
Enter test score 3: 74
Enter test score 4: 94
Enter test score 5: 79
Enter test score 6: 56
Enter test score 7: -1
Number of scores entered: 6
Test scores entered : 88 67 74 94 79 56

I have not been using pointers that long i most of my stuff has not needed them but now they do i need to learn how to use them more. I'm writing a program that simulates the squares most landed on(for fun) and i cant get a method to work because of an array pointer.
The error is no matching function for call to 'GameLoop::Loop(int, int (*)[4])'
Here is the latest version of the code. I've been editing a lot of things so there might be some stupid errors but I've tring everything.
rolling.h and rolling.cpp are just some dice function they are working perfect.
main.cpp
#include <iostream>
#include "Rolling.h"
#include "GameLoop.h"
Rolling Roll;
GameLoop Game;

I am writing a class that dynamically allocates an array that holds a user-defined number of test scores (test scores go from 0 to 10 both included). Once all the test scores are entered and validated (values only between 0 and 10, both included), the array should be passed to a function that sorts them in ascending order. Another function should be called that calculates theaverage of all the scores.The main program should display the sorted list of scores and the average of the scores with appropriate headings.

I define "Comwords" as a string, but apparently it takes the members as chars, then I can't set strings in a structure equal to the chars.
I see to also be having unknown problems with the ComMAL array and loading it values into another element of the same structure.
How to correct this? I was thinking of casting char elements as strings, but could find no reference in my library book regarding how to do that (lots on casting int's a doubles...)
Code:
int _tmain(int argc, _TCHAR* argv[]) {
int comm = 10;
int targ = 5;
int death;
struct AI_WORDS

Using a for loop, construct two 100 element arrays, x and y, such that element i of x stores the value sin(2*pi*i/100)) and the corresponding element of y stores cos((2*pi*i/100)). Print the values stored in the elements of x and y as you calculate them.
I have attempted to solve it but I'm not sure why the value 0 is only being printed, maybe I haven't assigned sin(2i/100)) and cos((2i/100)) to the arrays properly?
Code:
#include<stdio.h>
#include<stdlib.h>
#include<math.h>
int main () {

int arr[4][5];
for (int(&row)[5] : arr){
for (int &column : row){
} }
Why do we name it row instead column?
int arr[row][column]
Wouldn't this be like
int arr[4][5];
for (int(&column)[5] : arr){
for (int &row: column){
}
It just seems funny to me because we use row[5] which should be 4 if we meant row? Or did I read it wrong in C++ prime !?

I'm trying to write a function that takes a 32bit address and a data to store at this address.
I'm wanting to take the 32 bit memory address eg 0x12345678 and split it
into 4 x 2 bytes
12, 34, 56, 78
then each of the 4 entries is at most a 256 entry array.eg
FF, FF, FF, FF
So in this example, 0x12 points to 0x34 in the second array, which points to 0x56 in the third array, which finally points to 0x78 in the last array. This last array holds the actual data.
After successfully doing 0x12345678, say I might get a read for 0x1234AABB. So, the first and second pointers already exist, but I then have to create and write to dynamically created arrays.
The arrays need to have all entries set to NULL so that i know whether to follow the pointers to overwrite a previously entered value or create new arrays and pointers.
It all looks good and simple in the pseudo code I've written up but I'm having trouble coding it. I'm currently trying to deal with the first entry case, ie all array elements are NULL, but I'm getting confused with the pointers and creation of new arrays.
void cpu::store(unsigned int mem_add,unsigned int mem_val) {
int first = (mem_address&4278190080)>>24;
int second = (mem_address&16711680)>>16;
int third = (mem_address&65280)>>8;
int fourth= (mem_address&255);

A1 has been declared as
int* A1[256] ;

Basically on this assignment I must write program that inputs two positive integers of at most 100 digits and outputs the sum of the numbers into an array. The two positive numbers must come from different arrays and the sum has to be stored into another array.

For example if we have
array1[5]= {1,2,3,4,5}
and
array2[5]={2,3,4,0,7)
how do you sum them up as 12345 + 23407 . And when i say sum I mean normal mathematical sum.
here is my code:
int main () {
string str1;
string str2;

how to make the functions for b, c, d. if possible running through on how to would be more beneficial than just giving me the answer.
Global warming. As part of a global warming analysis, a research facility tracks outdoor temperatures at the North Pole once a day, at noon, for a year. At the end of each month, these temperatures are entered into the computer and processed. The operator will enter 28, 29, 30, or 31 data items, depending on the month.
You may use 500 as a sentinel value after the last temperature, since that is lower than absolute 0. Your main program should call the read_temps(), hot_days(), and print_temps() functions described here:
(b) Write a function, read_temps(), that has one parameter, an array called temps, in which to store the temperatures. Read the real data values for one month and store them into the slots of an array. Return the actual number of temperatures read as the result of the function.
(c) Write a function, hot_days(), that has two parameters: the number of temperatures for the current month and an array in which the temperatures are stored. Search through the temperature array and count all the days on which the noon temperature exceeds 32F. Return this count.
(d) Write a function, print_temps(), with the same two parameters plus the count of hot days. Print a neat table of temperatures. At the same time, calculate the average temperature for the month and print it at the end of the table, followed by the number of hot days.

scanf ("%d", &n);

Now, this is what I've been able to do so far, i know it's very basic but I just started learning programming! I tried different methods found on internet but none of them work for me. I want to find the intersection of arrays a & b then put them in array c(or just display them?)

I am attempting to assign "randomChoice" as the array index of the "listOfWords" array then copy "listOfWords[randomChoice] to "selectedWord". I am not sure if it is that I do not fully understand the use of strcopy() or something wrong with my arrays.
This is my error:
Code:
hangman.cc: In function ‘void SelectWord(char (*)[80], int, char*):
hangman.cc:84: error: invalid conversion from 'char' to 'const char*' And my code:
Code: #include <iostream>#include <fstream>
#include <cstdlib>
#include <cassert>
#include <cstring>

This is a function that is supposed to add two different arrays containing 9 items together, but it has a problem when it comes to doing any actual adding.
Code:
int * add_data(int x[], int y[], int z[])
{
int i;
char a[9];
for (i=1;i!=9;i++)
{
printf("%d =x
", x[1]+y[1]);
x[1] + y[1]= a[1];
}
return a;
