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;

I have a struct called Array and I'm to create a function to create a dynamic array that's fill with randomly generated integers from 0 to 50 (inclusive) and a function to destroy the array for freeing its memory. Below the code that I have written so far.
Code:
* Struct */
typedef struct {int *pArray; //the dynamic array
int length; //the size of the dynamic array}Array;
/* Function to create a dynamic array */
Array *initializeArray (int length) {int i;
}

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 <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.
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;

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 need a simple adjacent_find() to find the adjacent same letter in a randomly generated string?

I am trying to create an array with 800 element that are randomly arranged within the array. Once this is complete i want to use the bubble sort algorithm to organize the number in ascending order. I have the following code but it doesn't seem to work,

I have a map that is full of 4+ rooms each with one randomly selected door on one of its sides. I need to create a tunnel connecting all of the doors together. I'm not sure the best way to do this A* seems to complicated for me to do at the moment and I cannot think of a way to connect these rooms.
My world is currently a vector<vector<Tiles>> and the tiles contain entities like tunnel, wall, stair, floor, etc.
I am interested in creating a file of a given size and then randomly accessing the file to populate it. Is there a way to quickly create, for instance, a 4 GByte file in C++, initially populated with garbage?

I'm creating a roguelike/ cave exploration game, and I've created a lot of it, but I am having problems with item creation. The item is supposed to be the '*'. I know what the problem is (I'm setting Dmap to map after creating the item, but before outputting Dmap), but I don't know how to fix it.Also, I don't really know how code optimization works.I'll split my code between this post and the comments:

#include <stdlib.h> /* srand, rand */

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];

What did i wrong? is Visual studio 9.0 Visual studio 2008?
I tried compile in mode x64 than it works. but in Win32 it goes errors.

View 1 Replies View RelatedI 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?
View 2 Replies View RelatedWrite 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 very much a beginner at C and a large amount of it still tends to go over my head, I've created a 2d array which its size is generated from user input and filled with random integers. Next I need to locate the maximum and minimum figures in the integer and as dull..This is the code I have so far

So I have a vector that I want to iterate through randomly, and by random I mean that each element is only accessed once but I don't want to shuffle the vector because the vector elements are large. So I want this functionality:
std::vector<SomeLargeObjectWithoutACopyConstructor> myvec;
// ...fill myvec
std::random_shuffle(myvec.begin(),myvec.end());
for (auto& value : myvec)
{
// do stuff
}
Only I don't want to do this because the object type has no copy constructor and is large, so I don't want to shuffle the vector, just the iteration path. Is there a simple and efficient way of iterating randomly through a vector while ensuring that each object is only accessed once?
Is it possible to loop randomly. For example
for ( int i = 0; i<= 6 ; i++ )
I don't want i to acsend from 0 to 6 but i want it to get all numbers randomly. For example
first time r = 5 second time r = 2 and so on
until it gets all the seven numbers
I am making a game and I am attempting to get the zombies to move randomly but for the life of me, I simply don't have the knowledge with srand to do it
