C/C++ :: Expected Outcome Error On X Amount Of Rolls
Feb 20, 2015
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 pretty new to C, and keep getting an error. Basically I'm trying to convert a ppm image to all red. Here is my code that I can't get to work:
Code:
change(pixel_t *PIXEL, &w, &h,pixel_t *buffer);
And here is the beginning of my convert function:
Code:
void change(pixel_t *pixel, int w, int h, pixel_t *buffer) {
int average, sum;
int i;
pixel_t *pointer;
Everything else works fine. I keep getting an error when I call the convert function. It says "expected expression before pixel_t" and "too few arguments to function "change". I know that everything else in the main is working.

I'm trying to make a program that allows the user to input an arbitrary amount of numbers and finding the largest of all the inputs but I keep having problems with the output.
javascript:tx('
#include <iostream>
using namespace std;
//******************************************
//CLASS COMPARATOR
//******************************************
class comparator {
public:
comparator();
[Code] .....
And regardless of what numbers I enter, I always get the output of 10. Also I got the EOF idea from my textbook so if there is a better way of doing this I'd like to hear it. I don't know any clear ways that looks nice to end the while loop when the user doesn't have any more numbers to enter.

We have to make a code to detect the frequency of printable characters. But when I run the code, sometimes it can't detect the Uppercase Letters. But it can sometimes. It's a bit buggy, and it really can't get the frequency of the space character.
Does textcolor affect the outcome?
Code:
#include<stdio.h>#include<conio.h>
int main ()
{
clrscr();
char name[40],sentence[1000],ch;
int c=0,count[95]={0};
textcolor(LIGHTCYAN);
[Code] ....
I also noticed that it stops detecting the frequency when there is a space between character/s.

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'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?

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();

I wrote a program, that generates 20 random integers, and stores them in an array. Then I decided, to build more functions to it, i.e why not have it to display the lowest integer of an array. I created my function,
Code:
int minValue( int field[ ] )
and got my code in side, which (technically) works. In my main() function I'm calling
Code:
printf( "The smallest value of an array is: %d
", minValue( field[] ) );
and I'm getting an error trying to compile it.
Code:
randomArray.c:62:74: error: expected expression before ']' token
printf( "The smallest value of an array is: %d
", minValue( field[] ) );

This is what i have example code in c++:
#include <iostream>
class Foo{
public:

This first Dowhile loop is saying "expected unqualified-id" at the do and while parts. What does that mean
do {

do {
std::cout << "Give me a test result or grade from 0 to 100 for class"<< 1 << std::endl;
std::cin >> mathaverage[mathtestcount];

I have a global var (m) with an initial value 5.
I have a template class (A) that derives from a either a base class that has a member (_A1.m) or not (_A0), based upon it's template parameter. class (A) has a member function (fn) returns the value of (m) as it understands what (m) is.
However, this gives different results compared with a non-template class in a similar scenario. I'm expecting that if derived from _A1, that m should be taken from the base class scope and if derived from _A0, it should be taken from the global one.
Here is the code for your amusement:
int m = 5;
class _A0 {
public:
_A0(int) {
[Code] ....
This compiled using g++ 4.5.3 and 4.6.3 with the same results:
Global value of m is: 5
B0 class has no internal m member. Object resolves m internally with value 5
B1 class has internal m member. Object resolves m internally with value 3
A<_A0> class has no internal m member. Object resolves m internally with value 5
A<_A1> class has internal m member. Object resolves m internally with value 5

In this code:
#pragma once
#include <iostream>
class CBox // Derived class {
public:
// Constructor
explicit CBox(double lv = 1.0, double wv = 1.0, double hv = 1.0) : m_Length(lv), m_Width(wv), m_Height(hv){}
[Code] .....
Before the program ends, at return 0;
I would expect the CBox destructor to be called 3 times but it is being called 6 times? Why? Also in this code:
#pragma once
#include <iostream>
class CBox // Derived class {
public:
// Constructor
explicit CBox(double lv = 1.0, double wv = 1.0, double hv = 1.0) : m_Length(lv), m_Width(wv), m_Height(hv){}
[Code] .....
Why is the destructor called 3 times? When have you really destroyed a CBox? Doesnt emplace only create it and store it, then thats it?

I just wrote the following simple program:
Code:
#include <stdio.h>
#include <math.h>
int main(void) {
float fx, x;
[Code] ....
The output increases x by 0.1 as expected until x=1.5. After that x becomes 1.600001 and not 1.6 as expected.

I'm trying to perform a simple input operation, and check to make sure that whatever the user input is a valid input (is within data type bounds, is correct data type...). But when I get to ignoring the input, I keep getting an error.
unsigned short num;
while (true) {
std::cin >> num;
if (std::cin.fail()) {
num = 1;
[Code] ....
I don't fully understand why this error is here.

I am trying to parallelize some of my code with OpenMP. When I switch to using multiple threads I start getting random numbers that are out of the expected range.
Here is a small example:
Code:
#include <stdio.h>
#include </usr/local/include/gsl/gsl_rng.h>
#include </usr/local/include/gsl/gsl_randist.h>
int main() {
int mySeed=0;
const gsl_rng_type *T;
T = gsl_rng_ranlxs2;
gsl_rng *r_1 ;
[Code] .....
gsl_rng_uniform should only output number in the range [0,1) but with multiple threads it outputs larger number as well.

I tried my best but I can't figure out the problem. At the last part of "createArray", I output the final array created. I mean it to repeat once but then it repeat more times than I expect. createArray is an iterative function. If it repeats 3 times, than at last the array created which fulfil the criterion would be printed out 3+1 times.
I am trying to create an array with 3 numbers 5 times, resulting in a 2D array. The 3 numbers in a array are picked from 0 - 5. I enter createArray(5,3,5). Then these 5 arrays are compared with each other to see if there are repetitions. If there are, the whole process begins again, 5 arrays with 3 numbers each will be picked again and compared with each other. If there are no repetitions at last, there 5 arrays would be printed out.
void deleteArray(int** array){
delete[] array;
}
int** createArray(int simu_times, int randomrun,int numberofrun){
vector<Int_t>fChosenRun;
int** Array = new int*[simu_times];
[Code] ....
