So I made a code that shows a simple rectangle. How do I make it move using data structures? :)
Code:
#include "Glut_Setup.h"
#include <stdlib.h>
#include <stdio.h>
#include <iostream>
#include <vector>
#include <time.h>
using namespace std;
float P1= -5;
float P2= 2;
[Code] .....
So this makes an output of the head (a square), and the leg (rectangle. How do I make my points into a data structure in the shortest yet simplest way possible?
#include <vector>
#include <time.h>
using namespace std;
#include "Glut_Setup.h"
float
head1x= -0.5, head1y=3, head1z=0,
head2x= 0.5, head2y=3, head2z=0,
head3x= 0.5, head3y=2, head3z=0,
head4x= -0.5, head4y=2, head4z=0;
[Code] .....
I am trying to read from a data file that has input as :
12.0, 11, 123
14.0, 12.1, 3
And I want the program to read the data from the file and then make it into an array of structures and then print that array afterwards.
Code:
#include <stdio.h>
#include <stdlib.h>
#define MAX_INPUT 1000
int n =0;
int i = 0;
typedef struct {
double x[MAX_INPUT];
[Code] .....
The program when run gives the following output:
Ishtiaque-Mohammed-Khans-MacBook-Pro:Comp20005 IshtiaqueMKhan$ gcc -Wall -ansi -o ProjectB ProjectB.c
ProjectB.c: In function "main":
ProjectB.c:59: error: incompatible type for argument 1 of "print_array"
How to move a rectangle in TabPage ?
View 2 Replies View RelatedI'm working with a game editor program, where the player can create their own maps. Right know I'm working with collisions, and since it's unpredictable where the player place the objects like trees, houses and cars...etc have I an idea with making a rectangle selection tool. Where the player can drag a collision box around the object, so the sprite stops when it hits the box. The problem is that I dont know how to make a tool like that. so my question is how do I create a tool like that (see picture under for more information)?
btw I'm using the SDL framework
here is a picture that illustrate the tool I want to create: [URL] ....
What c++ code can be used to make an 'X' move through a maze. I have some code, but I'm not sure where to go from there. I have divided the program into three files, A header file, a main file and a .cpp implementation file.
In my implementation file I have:
#include "Maze.h"
Maze::Maze() {
} void Maze::mazeTraversal(char maze[][COLS], int row, int col, int direction) {
enum Direction {DOWN, RIGHT, UP, LEFT};
switch(option)

I was wonder if I can make 2 different size structures in a file. I wrote a code but It's apart of my school project and I havent compiled it yet, so Im just wondering will this work?
Code:
if((stsPtr = fopen("status.dat", "rb")) == NULL){
prinft("File could not be created/opened.
");
Error();

I would like to know how can I make a simple program .exe so that I don't have to open it through code blocks every time.

So for class I have to make an array of structures for a basic contact list in a phone.
I understand the bones of the program and how to go about doing most of it but as far as arrays of structures go I am blind.
Code:
struct phone
{
char FirstName[16];
char LastName[16];
int Number[11];
};
struct phone numbers[friends]; //friends is a variable assigned by the user What I am a bit confused about is say the user enters 30 as how many friends they have. How would I assign a value to the 3rd struct for LastName?
Consider I have a rectangle like this:
Point p1(100,100);
Point p2(300,200);
Graph_lib::Rectangle r(p1,p2);
And also I have a function that takes a rectangle and returns a Point of that, say, top-left corner of that rectangle. For example:
Point N(Graph_lib::Rectangle R1);
My question is that, first, how to send that Rectangle r(p1,p2) to the Point N(Graph_lib::Rectangle R1) function? And then, how to return a Point from that function?

when it comes to programming. I was trying to make a simple letter guessing game where the user has 6 chances to guess the letter V. The command prompt works fine until the user enters 'y' to play. It repeats my HIGH & LOW statements twice before letting me guess again. It's all a mess.

View 7 Replies View RelatedOk so I am working on a game and I'm in the process of developing my Player class. Anyways, what I have is a keyboard function that is called in my main function to make a shape move.
void myKeyboardFunction(unsigned char key, int x, int y) {
switch ( key ) {
[Code].....
But when I try to call it, trying to copy my previous method,
glutKeyboardFunc(Player1.playerControls);
I get an error
error C3867: 'Player::playerControls': function call missing argument list; use '&Player::playerControls' to create a pointer to member
I get an error saying it can't convert parameters. I would just like to understand why the arguments become a problem when I make the function a member of my class, when the first method I used is so easy.
I'm currently reading/programming from "Head first C#" book. I have this project which is making a program that has four dogs which race and there are three players that can bet on the race. I need to learn how to make the "dogs" (picture boxes) move from left end to the right end of a picture box.
Here is the code:
using System;
using System.Collections.Generic;
using System.Text;
using System.Windows.Forms;

I created one structure and the created structure is using in few more structures, but i did not get the proper data.
typedef struct _MSG_HEADER{
//MESSAGE_HEADER 40 bytes
short iApiTcode;
short iApiFuncId;
int LogTime;
char AlphaChar[2];
[Code]...
My requirement is have to fill the MessageHeader structure & we can use that header in all the structures entire program.
I'm taking a programming class and currently we're doing data structures. Today, we discussed how to save square matrices column-wise with data structures. The teacher said that after the first few steps where you declare the structure, allocate the matrix, free it and get the dimension (which mostly make sense to me I think), you have to "get" and "set" the matrix by putting in something like
Code:
void setMatrixEntry(Matrix* A, int i, int j, double Aij) {
A->entries[i+j*A->m] = Aij;
}

I'm reading the following file:
Osgood,Marcus 298542123 CHM FR mosgood@whatever.edu

Langlais,Susan 783323545 ME SR slanglais@whatever.edu
Davis,Nicole 987543345 PHY FR ndavis@whatever.edu
It's supposed to split it up into name, ID number, major, year, and email. The file reads it without any errors, and assigns name to the first part of the structure. However, ID gets assigned the ID, major, year, and email. Then Major gets assigned major, year, and email. Year gets assigned year and email, while email just gets assigned email. I don't know if it has something to do with the loop. For example, this is what I get what I print just the name and the ID.

Anyway. This is my function code for reading the array. I have it printing the ID number just to see if I can catch the errors earlier:
Code:
#include <stdio.h>
#include <string.h>
#include "functions.h"
void read_data(char filename[], studentinfo_t s[], int *size) {
FILE *infilep;
int countstudents = 0;
infilep = fopen("student_data", "r");

the name is reading correctly, but not anything else!
I need an explanation of what linked lists are. How the nodes are been defined and used, especially in an object oriented programming. With a code example.
View 1 Replies View RelatedI want to have input data stored in a database. All information entered is to be stored under a single block. That way whenever I want to recover that information all I have to do is point to that block. Think of it like this. I want a large square block that can hold certain information. Inside of that large block are a finite amount of smaller blocks in which the user entered information about a single subject. Lets say block 1 has a name, address, and phone number. The second block will have the same TYPE of information, but different values as entered by the user. I.E:
BLOCK 1: Name 1, Address 1, Phone 1
BLOCK 2: Name 2, Address 2, Phone 2
etc.
The large block contains all of the smaller blocks, we will name the large block "Address Book" ... How would I implement that? Of course it would be just a simple console program that would erase all information when the program shut down, but I've been trying to figure out how to do it, but just can't seem to grasp a good notion of how to do it. What would be the best way to do that? Structures? How would I make it dynamic so that I wouldn't have to define every block, so that it would be added on the fly when someone inputs new information.
We're writing a program in class using data structures and arrays and I'm stuck on writing a loop to find the students' highest test score. I only return the first student's ID, test score, and grade. For some reason unknown to me I'm not actually looping through all 12 or so records.
Code:
#include <stdio.h>
#define MAX_ENTRIES 50
struct records
{ //declare my student records structure
int ID; //the student's ID number
int test_score; //the student's test score
char grade; //the student's letter grade of aforementioned test score

I am trying to read the information from a .bmp file into my program while dynamically allocating memory for all of it. So I defined the structures for the headers and for a pixel, and then I have to read each pixel into a multi-dimensional array of pixels. I am completely new to structures, and definitely new to pointers combined with structures. I will have to use a filter with the information later, but right now I just want to read everything in correctly. The array of pixels will be two-dimensional -- the width by the height of the image, I guess.
Here's my code:
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
int main(int argc, char *argv[]) {
FILE *inFile, *outFile;

Why certain projects always roll their own data structures/utililiy classes rather than using the C++ standard libraries? such as linked lists and queues? Is there a particular reason for this?
View 11 Replies View RelatedThe program use a circular linked list and data structures to store the tasks.
- Every task should include a task name, a name for the person assigned to it, and the deadline for the task.
- Variables should be dynamic and their sizes should be determined at runtime based on the length of user input.
- You should implement the following functions (with appropriate arguments and return types) for your structure: add(), remove(), search(), and list().
- The add()function should add tasks alphabetically by task name. You do not need to implement any file operations.
- The search() function should be able search for a task by the task assignee name or the task name.
- The list() function should print records to the screen in the order they appear in the circular linked list.
- You should successfully deallocate all of the allocated memory before termination of your program.
