I'm doing a program about finding out the solution of a sudoku puzzle. I've been thinking about how I'm going to check every box of the small 3x3's. What would be the best and most efficient way of doing that?

I am trying to compile a c program for sudoku. I have declare const instances as global variables, but when i try to compile the code it says that my declarations are not constant, here is some of the code.
#include <stdio.h>
#include <assert.h>
const int GRIDSIZE = 3;
const int GRID_SQUARED = GRIDSIZE * GRIDSIZE; //this line
const int ALL_VALUES = (1<<GRID_SQUARED)-1; //and this give//the error
int board [GRID_SQUARED][GRID_SQUARED];
I have two unassigned variables A,B . My program goes as follows

This a program that makes a calculator in which this is a small portion of it, all the exponent numbers work exceptfor anything ending in 5.
Examples go as follow 2^3=8, 3^2=9, 5^2=24
I want to why this happens, is it because they are unassigned variables?
Some issues i had with my N puzzle code. I finished it and now i need to make a gui. It should respond the my code, and work according to my code. I never did something like this and i don't know where to start, what to read or what do to.

So my program is to check if a certain 9x9 sudoku grid is valid. i have to get the input through command argument. so for example.
./a.out sudoku.txt
So we have make my c program to use FILE I/O open and what not
program behavior must be as follow File does not exist.File contains something other than a sequence of 81 integers (too many, too few, non-int).
One or more of the values is not in the range 1..9 Violation of Sudoku rules (this is the big one!) In case 4, you should report the violation (or any one of the violations if there are multiple -- you do not need to exhaustively enumerate all violations).
For example: Row Violation: entries (2,2) and (2,6) are both equal to 7. (Similarly for column and box violations). All i know is that i need to make a 2d 9 by 9 array
I want to know if you have made Sudoku game in c++, which kind of data structure did you use? shortly, which part of the game did you use for? [Array, Stack, Queue, Linked List, Binary Search Tree]
View 5 Replies View RelatedAs it is known there are nine boxes and in each box we can put numbers 1-9 without repetition. I am trying to check a given filled Sudoku puzzle whether appropriate numbers are inserted in each of the nine boxes. For the time being I don't consider row repetition and column repetition. I wrote the code using loops and condition
I used 9*9 text-boxes. The names of the textboxes is sequential like for example for the first box
txt11,txt12,txt13
txt14,txt15,txt16
txt17,txt18,txt19
Actually, I used also the controls id to access the text boxes, and each box is checking with the neighboring boxes for equality both in forward -> and backward <-

So here is the code
public void BoxCheck() {
int start = 82, end = 74;
int i, b, f;
for (int p = 1; p <= 9; p++, start -= 9, end -= 9) {
richTextBox1.AppendText("Box " + 1);
[Code] ....
This works pretty fine, but is is the right way to do it? it is efficient? Remember for a full checking I have to include row check and column check as well, this is just for checking within each of the 9 boxes in Sudoku.
Dont know how to replace each letter as s number ... this is the question i was given ...
In cryptarithmetic puzzles, mathematical equations are written using letters. Each letter can be a digit from 0 to 9, but no two letters can be the same. Here is a sample problem:
SEND + MORE = MONEY
A solution to the puzzle is S = 9, R = 8, O = 0, M = 1, Y = 2, E = 5, N = 6, D = 7.
Write a program that finds a solution to the cryptarithmetic puzzle of the following:
TOO + TOO + TOO + TOO = GOOD
The simplest technique is to use a nested loop for each unique letter (in this case T, O, G, D). The loops would systematically assign the digits from 0 to 9 to each letter. For example, it might first try T=0,O=0,G=0,D=0, thenT=0,O=0, G = 0, D = 1, then T = 0, O = 0, G = 0, D = 2, etc., up to T = 9, O = 9, G = 9, D = 9. In the loop body, test that each variable is unique and that the equation is satisfied. Output the values for the letters that satisfy the equation.

I am creating a sudoku solver/generator. I have 81 text boxes on the form. I want the form to automatically clean up the input, eliminating alpha characters, and values under 1 or over 10. Anyways I have this method written, but I really don't want to go through and type up a change method for each text box. Is there to write a method that fires when ANY text box is changed, and gets the string value from the changed text box?

At the end, I need the output to print out the board states (user's path) of how he or she got the puzzle solved. This puzzle is the 15 Puzzle; but we have it to change by the user's input on what size they want to play (3x3 to 5x5). How to save the board state of each user input, then print those out in order from beginning to solved puzzle state. Subsequently, I would also need transferring the board state to change with using a vector to store the size based on user input. How to proceed, using a first search to solve the puzzle from the current board's state.

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.

The program need to find mean of elements in columns which are divided by 3. And to print which colmn has the greater mean
Example
For matrix:
7 9 5
17 15 30

Program print: 0 12 45. The greater mean: 3 column.
I wrote this code and it prints 0 12 45 idk how to find which column has greater mean?
Code:
#include <stdio.h>
#define max 50

I am writing a program to find the square root of a number. I am using the Newton-Raphson method..Just to clarify a bit of the code.. fabs(1/(x+1)) < 0.001 is to check for relative error..
EXAMPLE: for user entry of 100 if the iteration process ends in 10.055 the answer will return as 10 which is correct. But it isn't doing that.
It compiles I then proceed to run it..prompts me "Enter a number to find the square root of: I type 100 then hit enter...
"The square root of 100 is -1077834936"
My first time writing a program from complete scratch.
And I know there is a sqrt() function...just wanted to write my own.
Code:
#include <stdio.h>
#include <math.h>
double mysqrt(double a);
int main()
{
double a, result;
printf("Enter a number to find the square root of: ");

This is just the portion of my program. This program displays Not Found even if the id number is found.

char ID[10];
int i, found;
cout<<"Enter ID to search: ";
gets(ID);
found=0;
for(i=0;i<top;i++)

Here's the incorrect output
Enter ID to search: 111
Not found

I just want to remove the "Not found".
int main()
{
int a=0, c, d, N, K;

This is supposed to find take a number N and K and find all numbers between 0 and N that equal K and cout the number of pairs that fit it but it doesn't work.
