C++ :: Five Dice Roll - Read Out Average And Sum Of Rolls
Feb 7, 2013
My issue is that my program dies whenever it attempts to readout the average and sum of the rolls. I think I need to include the size function in here somewhere but am not sure how to go about it. Possibly scrap the "do while" loop and go with something else, or just am completely missing something.
Here's the code:
#include<iostream>
#include<random>
#include<ctime>
#include<vector>
#include<cstdlib>
#include<iomanip>
using namespace std;
int sum5(int d1, int d2, int d3, int d4, int d5);
int DiceRoll();
[Code] ....

I'm having a problem adding up the values of the dice rolls in a while loop. The program will only store the last value so how would I get it to store multiples values? Here is my program thus far. I would try an array but we haven't gotten to that yet.
#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;
int main() {
int die_1=0, die_2=0, total_score1, total_score2, player1score;
char enter;
[Code] ....
What operators or equation I should use to accomplish this?

I saw a program in which it uses rand like this:-
d1=rand() % 6+ 1;
where, d1 is any integer. The program is to simulate the roll of a dice. The whole program is this:-
Code:
#include<stdio.h>
#include<stdlib.h>
main() {
int i;
int d1, d2;
int a[13];

I am trying to simulate a random dice roll as a basis for a chutes and ladders game
Code:
int main {
int i = 0, diceroll;
while (i>5) {
diceroll = 1+rand()%6;
i++;
}
return 0;
}
However the numbers get don't seem to be random, it always starts off with 6,6,5.. then its random.

1): write program to c++ to read three numbers from keyboard and find the average of the three numbers?
2): write program c++ to read two numbers from keyboard and swap between numbers like x=4; y=6; the result x=6; y=4;?
I think that int can do that job. but im not sure.
3): must be the result of positive example: (x+(-y)=z)?
with abs ?
4): values for each of : X= ;y= ;z= ;

Why is it this does not print out the number?
The goal is to print 10 groups of 5 rolls per group, can't figure this out...

for an assignment we need to create basically a program that asks the user for the result of standard six-sided die rolls (numbers from 1 to 6). The program will prompt the user with "Enter a die roll or 0 to exit " for the first entry and Next die roll? for all subsequent entries. The program will continue reading die rolls from the user until the user enters 0. At this point, the program prints two newline characters (one blank line) and finally, the bar chart showing the number of times each die roll has been entered, and then terminates.If the user enters an invalid number, the program will just ignore it, and ask for another number. Only numbers 1-6 inclusive and 0 are valid.
Example output Enter a die roll or 0 to exit 6 Next die roll? 6 Next die roll? 7 Next die roll? 4 Next die roll? 0

I have a program that rolls two dice however many times the user specifies and counts the occurrences of each total (2-12). I have to compare the results of the random rolls to the expected outcome and give the percentage of error between the two.
I have an example that tells me the sum to expected outcome are as follows if I roll 36 times: 2/1, 3/2, 4/3, 5/4, 6/5, 7/6, 8/5, 9/4, 10/3, 11/2, 12/1 but I don't know how to put that into code to get the expected outcome for X amount of rolls.

I'm trying to draw and pivot a rectangle. How to get the new coordinates if I turn it 90 degree for example?
From this:
To this:
This is not good because it will reduce it in size.

I must write a function that has a one dimensional double array and the number of values in the array as its arguments. Normalize the values. I must also print the maximum, minimum, average and numbers of values above the average in the array.
The equation that computes the normalized value from a value x is:
Normalized x= (x-min(array))/(max(array)-min(array))
My code does not print the correct normalized value, average and values above average.
Code:
#include <stdio.h>
int findMax( double array1[], int num_elements) // This function computes the maximum value of the array
{
int i, max=-32000;
for (i=0; i<num_elements; i++)

I am trying to average the negative numbers and positive number and of course the total average.
This will read in a list of n values, where n is not known ahead of time. The number of values read into the array will be saved in n.
vector<int> readList() {
std::vector<int> result;
ifstream inFile;
inFile.open("setA.txt");
for (int x; inFile >> x; ) {
result.push_back(x);
[code]....
array is a one-dimensional array of integers and n is the number of elements in that array that contain valid data values. Both of these are input parameters to the function. The function must calculate 1) the average of the n integers in array, storing the result in ave; 2) the average of the positive numbers (> 0), storing the result in avePos, and 3) the average of the negative numbers (< 0), storing the result in aveNeg.
void avgs (std::vector &array, int &ave, int &avePos, int &aveNeg) {
int sum = 0, pos_sum = 0, neg_sum = 0, pos_count = 0, neg_count = 0;
for (auto i : array) {
sum += i;
if (i > 0) { pos_sum += i; ++pos_count; }

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?

I'm very new to C Programming and am doing some homework for my intro to C class. "There is a game where one can play and bet money on. Two dice are rolled and the numbers that appear on the dice are added together. If the total is 7 or 11, then the user wins. If the total is 2 or 12, then the user loses. If a different total appears. then the user gets their money back."
I have written the program below:
Code:
#define _CRT_SECURE_NO_WARNINGS
#include <stdio.h>
#include <stdlib.h>
void main()
{
int d1,d2,sum;
d1=0;
d2=0;
}
[code]...
However, after finishing the program, I realized that I NEEDED to use random numbers!!! How do I make my program generate random numbers within a range of 1-12? Also, how do I make my program generate NEW random numbers EVERY TIME instead of ONCE??

I made this dice simulator which basically throws the dice 1 million times and outputs the frequency and percentage average for each side (1 to 6).
Everything is working fine, except my averages (floats) seem to be rounding up, causing 4% being "unassigned" at the end of the million rolls. I'm outputting with a setprecision of 2, but I only get 0's and no fractional numbers.

I have written the code below that allows the user to input any sided dice and any number of rolls. The program will print out the output in sequence. I need to sum these outputs into one number, but I am having trouble writing a sum function for this.
//This Program Creates the Sum of a Number of Dice Rolls of the Same Size
#include <stdio.h>
#include <math.h>
#include <time.h>
int rolldie();
int main(){
int x, n, a; //'x' n=number of rolls, a=number sided dice
[Code] ....
The output looks something like this currently:
Please Enter the Number Sided Dice Followed by the number of Rolls... 12 10
4 12 2 10 12 5 5 12 12 5 >Exit code: 0

I'm trying to create a program that rolls a dice a few thousand times and print out how many times it lands on each face and then print out a graph using x's as a visual representation using classes.
output looks like this:
1 --- 2000 xxxxxxxxxxxxxxxxxxxxxxxxx
2 --- 1950xxxxxxxxxxxxxxxxxxxxxxxx
.
.
6 --- 2050 xxxxxxxxxxxxxxxxxxxxxxxxxxx
I need a method called int count(int face) inside my class that returns the number of times a particular face has appeared, I just don't know how to incorporate this. I think I should use a constructor and destructor but i'm new with those and knowing when to actually use them.
Here is what I have so far that shows how it should look when printed, just struggling to convert using a class.
#include <iostream>
#include <vector>
#include <cstdlib>
#include <ctime>
using namespace std;

The only difficulty im having is creating a class and methods & being able to access them from my win form app. Can i get a few tips on the do's and donts of creating classes / methods and accessing them from form app.
This is what i have put together so far.

I am making a program where a computer and player take turns rolling dice.
There seems to be an issue somewhere in my loop where when the player selects from the possible dice choices, it rolls for the computer and does not select the choice and it immediately becomes the player's turn again.
I am trying to get it to where when the computer rolls the dice, it should display the list of possible values, and ask the user to hit the enter key in order for the computer to choose which value to select using the following command:
Code:
while ( getchar() != '
' ) ; I've tried it a hundred times and no matter where I put the command it still skips the computer's turn.
Below is my code:
Code:
while (compscore < 99 && playerscore < 99){
printf("You have rolled the following pair of dice:
");
a =("%i ", rand() % (MAX_VAL - MIN_VAL + 1) + MIN_VAL);
b =("%i ", rand() % (MAX_VAL - MIN_VAL + 1) + MIN_VAL);
multiply = a * b;

I am building the game risk and I want to start off with a dice rolling mechanism. In risk 5 die are needed so I want to know the most efficient way of churning out the code for this. Since the players have the options of rolling 1, 2 or 3 die (max 3 for attacker, and max 2 for defender) I was thinking something like this after searching the web for a few different options:
const int minNum = 1;
const int maxNum = 6;
int numberGenerator(){
int x;
x = minNum + rand() % (maxNum - minNum + 1);
[Code] ....
Since I will be asking the player the option to choose how many die to roll, is this the most efficient way? I want to compare the total sums after the die are rolled. If they choose 3 dice (the attacker) I will simply call the first 3 methods and either 1 or 2 for the defender.

I am writing a snakes and ladder program and I'm almost finished, but I am struggling with the dice to work in the way I want it to work. I want the dice to work like this :
Before each player throw the dice they must start at 0.
Each player must throw a 6 on the dice to move on the board.
If a player threw a 6 on the dice, that player can throw again.
But I ended up with two seperate dice, one for each player (game is only for two players).And when I run the program, both players don't start at 0. And when I throw the dice, both players move at the same time but with different values.
If one of my players threw a 6, they just keep on throwing until someone wins the game. I tried to use a switch and if statements but I couldn't get it right. And so I did this :
Code:
#include<stdio.h>
#include<stdlib.h>
#include<windows.h>
#define SpaceBar 32// 32 is an ASCII value for a spacebar

I wrote a code that mimics a dice, my code so far will ask for the user to input a number at which they want to hold or no longer throw the dice, it will also ask the user how many roll simulations they would like to do.
If a 1 is rolled the turn is over and the score is 0
After this input is recieved the code goes into a loop until the values have been met.
I would to add probability to my code so I need to know how many times a certain number was rolled and this is where I am stuck.
An example of how I would like my code to work, let's suppose hold at number is 17
We role the dice until we roll a 17 or larger, but if we roll a 1, then our score is 0.
Let's suppose the number of simulations is 5 and for simulation 1 we roll
2 + 5 + 6 + 4 = 17
and for simulation 2 we roll
5 + 4 + 1, but since we rolled a 1, the score is 0,
for simulation 3 we roll
3 + 4 + 5 + 6 = 18
for simulation 4 we roll
4 + 4 + 6 + 6 = 20
for simulation 5 we roll
3 + 4 + 5 + 5 = 17 so that means we got
0: 1 time 1/5 = .20
17: 2 times 2/5 = .40
18: 1 time 1/5 = .20
19: 0 times 0/5 = .00
20: 1 time 1/5 = .20
21: 0 times 0/5 = .00
22: 0 times 0/5 = .00
In other words the idea is to roll a 17 or larger (or whatever the hold number happens to be), but if you roll a 1, then your score is a 0.
