I am writing for loop with a switch so that scores can be inputted in by a judge. The issue that I am running into is that I will put out an the text then the test happens and the code puts out the switch statement 5 times with random number. Here is what I have written.
Code: int main() { int diver; int option; int Judge; cout << "Enter Divers Name:";
How to create .cpp file (new class) that will handle all the random number generators (<random> library) that main could possibly access. When I looked for a way how to implement random generators the examples were always in the main function or in a class in the main.cpp (with no header file and the generator was not seeded as I imagine it should be = only once in a program).
Questions follows after this malfunction code.
main.cpp #include "randomizer.h" int main() { Randomizer randObject(0, 10, 125); //Set bounds and seed generator int mainVar = randObject.getRandInt(); //Store newly generated random number for future work
[Code] .....
1) So I think that I should somehow declare these generators and distribution in the header file. Is it like declaring int a;?
I tried writing std::default_random_engine defGen; into the header file which only silenced compiler's errors but defGen wasn't seeded.
I have seen some examples using auto a = randInt(defGen); (or maybe with the use of auto a = std::bind.... But what does auto represent? I can't use it in the header file.
2) Can I ensure that the randObject is seeded only once? If for examle I need randObject2 with different boundMax, can I still use the same defGen which was seeded the first time? That should ensure better "randomness" through the program, shouldn't it?
3) Is there better way (and easy too) to "interface" random number generators? The class in the end should provide "get" function to acces int, double, bool, signed/unsigned... or some other specialities like random prime numbers, etc.
If it is anyhow related I am using Code::Blocks IDE with GCC compiler (4.7.1)
I'm unable to use the function random(num); in Code::Blocks. It shows the error : error: 'random' was not declared in this scope while the same code works fine in Borland's Turbo C++. How do I rectify this?
I'm running a game online and designing a program to generate Enemy Stats. Basically, it's supposed to generate 25 numbers between 0 and 7(to represent 8 Attributes on a 25 Point Buy system) and count how many times each number shows up.
Here's what the code looks like:
Code: #include <iostream> #include <ctime> #include <cstdlib> using namespace std; int Generate() { int r= rand(); int s= r%7; [Code] ....
I will keep this simple as I have the code written for my testing software program, I just want to add a feature of randomly generating the answer choice output order, I do not want to randomly output the full questions, but instead the choices (answers to the question), for example =
As you can see I would like to output the answers, choices randomly as in answer choice 3 will appear at the top instead of 1. and so on, it doesn't matter if the numbers move with the txt as the numbers beside the questions are txt.
I am working with C++ in Visual Studio. It's my first semester doing anything like this ever. Still, I am embarrassed that I am having trouble with this simple "coin flipping" program. The user tells the program how many times to "flip the coin" & then the program tells the user the results of each flip. You'll see I am randomly generating a 1 or a 2 within the function coinFlip to represent heads or tails. However, the problem is that if the user wants more than one coin flip, the "random" number stays the same for all of them, resulting in all heads or all tails. I am thinking this is an issue with the for loop that I have within the function coinFlip.
I seem to get an error after int main (void) saying 'a function definition isnt aloowed here before { token? And then also at the end of main saying 'expexted } at end of output?
My programme is trying to create a random array of 100 ints between 0 and 250, sort them and print them.
Here is my code:
#include <iostream> #include <stdio.h> #include <stdlib.h> #include <time.h> #include <cstring> void bubbleSort(int *array,int length)//Bubble sort function { int i,j; for(i=0;i<10;i++)
I can't compile this code as I am at work and the computers are security protected, So i''l have to wait until i get home to test this, but I am pretty sure I am wrong. The problem is I have to create two vectors with 10 elements and input random numbers into it, then pick one of the elements of the second vector at random and append it to an element from the first vector at random. This has to be done 10 times and the I am assuming i have to print the 10 results. This is what I have:
#include <cstdlib> #include <ctime> #include <iostream> using namespace std; int main() { vector<int> random (10);
#include <iostream> #include <fstream> #include <cstdlib> #include <ctime> using namespace std; int main () { ofstream fout("datain.txt",ios::out); int array[6][6];
I am currently using Flash. Here are two images I will be referring through without this post:
1: [URL] ....
2: [URL] ....
So basically, when I click the generate buttonon the first image it takes you to the second image. What I want is when I click the generate button it comes to this screen, aswell as choose a random word from each list that I will make (Who List, What List, When List, Where List, and Why List) and place the word next to its position. When you click New Idea I want it to also generate another set of random words from the lists. How can I do this?
I'm trying to write a program that generates a random number between 50 and 200. I made a program that generates random numbers, but how to make those random numbers be in-between 50 and 200. Any example of a program that generates random numbers that are confined in-between certain values?
I have a array that has 10 quotes inside, and I want to put a random number between 0 and 9in these -->[] , so that when I press the button a random quote will be shown.
private void Random_Click(object sender, RoutedEventArgs e) { string[] Quotes = new string[10]; // List with quotes Quotes[1] = "Life isn't about getting and having, it's about giving and being."; Quotes[1] = "Whatever the mind of man can conceive and believe, it can achieve."; Quotes[2] = "Strive not to be a success, but rather to be of value.";
I've been having 3 days worth of difficulties with a part of my code for a moving-a-robot-around-blocks problem.
No error messages; it runs, it just, sadly, isn't doing what I want it to do.
When I isolate the random-number generating part of the code, it works just fine and give me numbers 0-7. However, when I put those random numbers into another functions to use them as x and y coordinates in the matrix (in order to randomly position 10 blocks, represented by the number 10), and then go to print the matrix (which should be all zeros except for 10 100s), I get a large random number in each position.
#include <stdio.h> #include <time.h> int getXCoordinates() //this function gets random x-coordinates in matrix { int x; x=rand()%8; // random number 0-7
I made a function that provides random number to a matrix. The function works fine but with one problem, every time i call the function it provides the same numbers to every matrix.
void randomMatNumbers(int **p, int rows, int cols) { int i, j; srand(time(NULL)); for(i = 0; i < rows; i++) { for(j = 0; j < cols; j++) p[i][j] = (rand() % 199) - 99; } }
