I want to display the content of point "cell", how can I implement this:
Here is the code:
#include <iostream>
#include <utility>
#include <conio.h>
#include <stdio.h>
using namespace std;
int main () {
typedef pair<int,int> point;

//Introductory20.cpp - displays the contents of a two-dimensional array, column by column and row by row
#include <iostream>
using namespace std;
int main() {
int nums[2][4] = {{17, 24, 86, 35},
{23, 36, 10, 12}};
[Code] .....
I need modifying a program that should display the contents of the two- dimensional array, column by column and also row by row. I need to complete the program using a WHILE statement in the outer loops and a FOR statement in the nested loops.
I want to:
1. Load HTML File (or take stuff from string)
2. display window with content of that html
so yeah, basically something like a browser, is there some lib that will just load html and do it for me? I dont need whole browser, I just need to show really simple html pages in my app....
I'm coding a hangman game. I'm trying to store user entries so i can output them to show the user what they have already entered. Problem is that it's not display anything at all.
I'm trying to store multiple characters of course, and then display all characters stored.
char guess[27]={0};
cin >> guess[26];
int hit=0;
for(int i=0; i<len; i++) {
if( guess[26] == hidden_word[i] ) {
hit++;
select_word[i] = guess[26];
if(strcmp(hidden_word,select_word) == 0) {
[code]....
EDIT: I also get the error - Stack around the variable 'guess' was corrupted. At the end of the game.
i want to display all the contents of a file excluding one based on user input say i have 4 records in the file numbered 1 to 4....the user chooses 2 to exclude it outputs records 1,3,4,4 when it should be records 1,3,4 what am i doing wrong here is the code.its basically displaying the last record in the file twice
void excludeRecord()
{
ifstream read;
read.open("Data.txt");
int recordC =0;
string fnameC = " ";
string lnameC = " ";

I am coding in C++ an implementation of BTree Insertion. I want to display the contents of the Tree in a per-level format. After writing functions and trying to run. I get the error Undefined reference.

Write a program that prompts the user for the x and y coordinates of a point on the x-y plane, and then displays the position of that point in polar coordinates.
The program must execute via a function ‘polar’ that is called from the main function. This function accepts x & y coordinates as input value parameters, and then returns, through reference parameters, the polar coordinate position of the point (r and theta).
Could in theory be written entirely in the main function; however, to meet the problem statement the code must include a user defined function that returns polar coordinates to the main function via reference parameters.
Some programming hints:
(i)Reference parameters are declared using an ampersand after the declaration type: for example – ‘int& number’ declares a reference parameter ‘number’ of type ‘integer’.
(ii)You’ll need the cmath library for arctan and sqrt functions. The C++ syntax for the arctan function is “atan(x)”.
(iii)The C++ arctan function returns an angle in radians. For output to the screen convert the angle theta from radians to degrees.
(iv)Program should work for x, y values in all four quadrants of the x-y plane.
I'm trying to write a code that displays lines between user designated points with circles at each point, but I can't get the lines to display! I'm at a loss on what to do and need fresh eyes on the subject.
#include <iostream>
#include "graph1.h"
using namespace std;
//Function Prototypes Follow
void getNoPoints(int* no_points);
void getPoints(int* x, int* y,int no_points);
void drawPolyLine(int* x, int* y, int no_points,int objects[]);
[Code] ....
I imagine the error is in this segment:
int i=0;
for (i = 0; i < no_points;) {
objects[i] = drawLine(x[i],y[i],x[++i],y[++i],1);
setColor(objects[i],255,255,0);
}

So I insert values from a vector into a list and into a multiset, and I noticed zero is added to their contents! I had to do a whole lot of debugging to find out where the error was, how can i stop this thing? Code which generates such error...
infact i checked the content of vector ups to be sure that there was no zero in it, but after loading into list combi_t * head, it seems like there was a zero added and this is giving me errors when i call function master_roller...
Code:
void ins(combi_t * &testa, int &numero, int &num, int &no)
{ // if (ricerca(testa, numero) == 0)
//{
combi_t *temp = new combi_t;
temp->val0 = numero;
temp->val1 = num;
temp->val2 = no;
temp->nextPtr = 0;

I would like to draw a border arround a cell in a TableLayoutPanel but without also making a connection between the columns. I just want an outer border.
private void tableLayoutPanel1_CellPaint(object sender, TableLayoutCellPaintEventArgs e) {
if (e.Row == 0) {
e.Graphics.DrawLine(Pens.Black, e.CellBounds.Location, new Point(e.CellBounds.Right, e.CellBounds.Top));
e.Graphics.DrawLine(Pens.Black, new Point(e.CellBounds.Left, e.CellBounds.Bottom), new Point(e.CellBounds.Right, e.CellBounds.Bottom));
e.Graphics.DrawLine(Pens.Black, e.CellBounds.Location, new Point(e.CellBounds.Left, e.CellBounds.Bottom));
}
}
This line
e.Graphics.DrawLine(Pens.Black, e.CellBounds.Location, new Point(e.CellBounds.Left, e.CellBounds.Bottom));
also paints connections, where i don't want them. How can i just make a outerb order arround a cell and is there a easier way to do it? Here's also an image of what i want. I don't know if i described it right.

I'm currently working on a Scheme Interpreter written in C. I'm trying to create a cons cell structure via recursive descent parsing, except instead of just having the car and cons, I also have a field that holds the token that I receive from the lexical analyzer (which was provided to us). The struct for what I'm describing is as such:
typdef struct node node;
typedef node* list;
struct node {
char* symbol;
list car;
list cdr;
};
Thus a cons cell would be (with a node represented as [symbol][car][cdr]), [null][car][cdr], while a symbol would be [symbol][null][null].
In the top answer for a similar question on Stack Overflow, one of the suggestions was to put the tokens into a stack as the input is recursively parsed, and then from that stack input it into the cons cell structure.
This is something that I'm working towards now, as it is easier for me to understand and I already have implemented a stack in C before, but I know that I can just build the structure recursively, I'm just not sure how. The following is code that I have:
list s_expression() {
list local;
list temp;
if (strcmp(token, "(") == 0) {
strcpy(token, getToken());
[Code] .....
s_expression is supposed to return a pointer to a recursively built cons cell structure. I'm just having issues figuring out when to call getToken(), as I either call getToken in the wrong spot and unintentionally skip over a token, or I call getToken() when I'm done getting all of the tokens, thus causing my program to continue searching for a token from user input instead of continuing on with the rest of the program.
When should I be calling getToken()?
In addition, what would be better, recursively building the cons cell structure as you go through the user's input, or putting all of the tokens into a stack and then building the cons cell structure using that stack?
If needed, I can post the lexical analyzer that's been provided to us. Also, for S_expression(); showing up as S_exp<b></b>pression();, I'm not sure what happened there. I copied this post from my question on stack overflow.

I have dabbled in programming with C, but I am not proficient enough to write a program dealing with files. I have to take an extremely long list of numbers that need to be placed into another file within a line of code for validating purposes. Taking the numbers from one file and placing them into another file with a string code around them?
