C++ :: Draw Simple Graphs To Have Visualization Of Output Generated
Mar 21, 2014
I am writing sample programs for graph problems like Dijkstra or Bellman-Ford algorithms. In Dijkstra, for instance, when I input my program a set of vertices and edges, ask to find shortest path from Vertex A to Vertex B, my program currently outputs shortest path from A to B. I want to display graph and have a visualization of the output generated. Is there a way to display nodes and connecting lines? What C++ classes would required achieve this?
I am trying to draw a grid for checkers. I could draw a square at the starting point from origin with the code below(attached the pic below how it looks) however I am not being able to draw a grid when the program runs.
#include "ccc_win.h" // GameDemo.cpp // Shows how to place a piece accurately on a grid after a mouse click. #include "ccc_win.h" // for graphics classes and functions using namespace std; int ccc_win_main(void) // main function for graphics program
I have a RGB STRIP connected to Arduino, when im communicating via Serial. All works great! So next i wanted to make some audio visualisation.. So i found some samples etc.. and then i created the Audio Visualisation via C# using BASS.NET, when R has been BASSes, G medium frequency and B high frequency. But isnt looking good, so i started thinking, what 3 variables in song has can use, but this is bad idea.. I got idea to change to random color when its get "beat" or BASS hit some value. I tryied 4 hours of doing it, searching, programming... But i cant do it...
So, my question is how to detect the beat or just anything event for Audio Visualisation. Best output form WASAPI. Only what i can do is get FFT and Audio Spectrum from WASAPI by BASS.NET, but thats all. My audio skills is so low for this.
I am learning c because I want to get back into programming microcontrollers, which I previously did in assembly. I wanted to make something fairly tight in terms of program memory and RAM to show me an output in binary form. When you are troubleshooting a file register or serial interface when you can see the actual bit values (on a small LCD for a micro-controller) and compare it to a datasheet.
Code: #include <stdio.h> #include <math.h> int main() { int i; int decimaltoconvert; int convertingarray[7]; int convertingarray2[7];
[Code] .....
Also, how might I go about putting that into a function that I could call?
I'm wanting to create an image, all I need is to be able to set RGB values and X-Y coordinates, I'm not wanting to read or manipulate images. Any easy to use library or another simple method of doing this?
I have a simple input output problem using float point numbers and after the first input the program skips the other cin functions is there something that I did wrong? It compiles fine also.
Code: #include <iostream> #include <float.h> using namespace std; int main() { int x; int y; int z;
I'm attempting to build a tool for a Minecraft mod called Thaumcraft. In it, there are various aspects of magic that are used in a little research minigame; basically, you have to link Aspect A to Aspect B by the aspects either used to make them, or the aspects that use them in their creation. I figured the easiest way to find a path from A to B would be to relate them via graph object, the code for which I found here, minus the IEnumerable<T> dependency on the Graph<T> class itself, because that requires I build an IEnumerator<T> class and it seems difficult I can do without.
Must be between MinSteps and MaxSteps (say, between 3 and 5 steps).Must use either a source aspect (as in, the current aspect requires it to be built), or a destination aspect (as in, the current aspect is used in its creation).An aspect requires two other aspects of a lower tier to create it.The only exceptions to the above rule are the Primal aspects, which require no aspects to build them.
Here's my Aspect class:
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Runtime.Serialization; using System.Runtime.Serialization.Formatters.Binary; using System.IO; namespace Pathfinder
I can't get the sum of two randomly generated numbers - I don't believe the program is adding wrong what I think might be happening is upon hitting enter its adding two new randomly generated numbers -
Code: // Program functions as a math tutor #include <cstdlib> #include <iostream> #include <ctime> using namespace std; int main() { // Constants const int Min_Value = 1;
The program is supposed to be printing 21 different numbers that are randomly generated. Why am I getting the same number 21 times? Using dev C++ compiler.
Code:
/*prints random numbers between 1 - 99*/ #include <stdio.h> #include <stdlib.h> #include <time.h>
How do i define a new color that is randomly generated in allegro.
I have this code here in the header file.
Code:
//FILE : circledefs.h //PURP : Define some constants for circle & background #ifndef CIRCLEDEFS_H #define CIRCLEDEFS_H #define NUMCIRCLES 3 //The frames per second for the timer #define FPS 60
[Code]...
And what i want to do here is learn how to create a random number gen. Now a few questions if you don't mind telling me is.
1 - can I create 3 random generators in this header file? Or do I have to do this in main.
2 - If I do have to do this in main can I still create this defined RANDOM as a color.
3 - I am sooooo new to this all i know is cin and cout code for C++, so will i need to know more about pointers to do this.
4 - for fun how hard would it be to make a game in allegro that uses music to define how the enemy moves and attacks. (yes that would be the final project.
So we're having an assignment for school where you code a Roulette game which simulates you playing and you can choose how many times you "play" to check how many times you'd win (if that makes any sense, im german :P)
Anyways, the problem is how do i store all the random generated numbers in an array while NOT doing this (it's just a snip):
Code:
void randomzahl(void){ int i; int zahl5[5]; int zahl10[10]; int zahl100[100]; int zahl1000[1000]; int zahl10000[10000]; if(runden == 5)
I have a error with one of my programs. I'm supposed to get rid of negative numbers when there are numbers that are randomly generated. Here is the middle part of the code.
{ int vectorLength = 10; vector<int> bothSigns(vectorLength); cout << " Input vector: "; for (int i = 0; i < vectorLength; i = i + 1) { bothSigns[i] = rand()%201 - 100;
[code] .....
The part where i'm supposed to start is after the /////'s. However, whenever I input a number for the random numbers(not put in part of code), i keep getting a segmentation error.
//This code gives randomly generated alphabets and if equal will cout the alphabet which is equal
1 #include <iostream> 2 #include <cstdlib> 3 #include <ctime> 4 using namespace std; 5 int main() 6 { 7 int a; 8 char array[10];
[Code] .....
My question is how to check that randomly generated alphabets are equal e.g in 22 number line it should give output of equal alphabets if they are equal but it does not give equal alphabets what wrong in this code mention the wrong statement, how will i get right answer?
I've been trying to create a roguelike, and I was trying to create randomly generated rooms like in Rogue. I'm seperating my map array into sections and giving it a 50% chance of spawning a room, but right now it doesn't do anything but spawn solid rock. What am I doing wrong?
int MapSizeX = 100; int MapSizeY = 100; char map[100][100] = {}; char wall = 178; int ViewDistance = 10;
Write a function that takes 3 arguments. The function has to bring back a new number that has been generated with the replacement of the figure that is on a given position in the number with a figure that is been transferred as an argument(have in mind that the position of the figure is being counted from right to left,starting from one). Write a main program in which the newly formed numbers will be printed for numbers of a range written by the user.
Example: if you wrote the numbers 2276,3 and 5 the function should bring back the number 2576
If you didn't understand the text, the example shows that in the number 2276, the number has been counted from right to left by the second argument "3" and in the place of the figure "2" has been put the figure "5".
This is where I got stuck, I can't figure out how to make the replacement.
int argument(int x,int y,int z) { return 0; } int main() { int a,b,c; printf("Enter a value for a(100-999):"); scanf("%d",&a);
I am fairly new to c++, and I want to be able to draw a polygon. When I have searched for how to draw one, the only thing i can find is scripts doing things like this:
* ** *** **** *****
I doubt that c++ is that primitive, and I'm looking for something like the c++ equivalent of this python script:
I'm trying to create a grid using the following characters: !, @, #, $, &.
It's an 8 x 8 grid, and should contain the characters in no particular order (trying to create a Bejeweled-like game).
I already defined the width and length to be 8, so:
#define WIDTH 8 #define LENGTH 8
Code:
void makegrid(char grid[]) { int j; int k; for ( j = -1; j < LENGTH; j++ ) { for ( k = -1; k < WIDTH; k++ ) { /* I don't know what to type here anymore :( */ } } }
