C++ :: Dice (with Varying Number Of Sides) Program To Calculate Percentage Of Results
Oct 28, 2013
I am trying to code and compile a program that requests a uses to first inpu the number of sides they wish for a dice to have and secondly input the number of dice throws they would like to calculate the value for. The program will print an error message and default the number of sides the dice has to 5 if the number entered is below 4. Finally it will print out a percentage figure for each value that results from all the the dice rolls.
I have attached my header, driver and class files below along with accompanying error messages below them
// file name Exercise.cpp
#include <iostream>
#include "Die.h"
using namespace std;
int main() // the main program begins here
{
char restart = 'y'; // declare variables
double numRolls = 0.0;
int diceTot = 0;
I am using codeblocks for school and I am trying to create a program to calculate a percentage for commission and a bonus. I have tried using a decimal for percentage, int and floats with casting. Every time it I try it displays 0 or just the bonus. I even took and did a test page. My head is about to pop.
Write an algorithm that can be used to calculate the commission earned in a real estate transaction. The chart below describes the formulas used to calculate the commission.
Sales Price Commission Less than $100,000 5% of Sales Price $100,000 to $300,000 $5,000 + 10% of Sales Price over $100,000 More than $300,000 $25,000 + 15% of Sales Price over $300,000
// Commission and Bonuses. #include <iostream> #include <iomanip>
Write a program that calculates the total grade for N classroom exercises as a percentage. The user to input the value for N followed by each of the N scores and totals. Calculate the overall percentage (sum of the total points earned divided by the total point possible) and output it as a percentage. Sample input and output it as a percentage. Sample input and output is shown below.
How many exercises to input? score1: 10 total points possible: 10 score2: 7 total points possible: 12 score3: 5 total points possible: 8
Code: # include <iostream> using namespace std; int main () { double N=0, score, total, totalScore=0, totalGrade=0, GRADE; cout<<"How many excersices will be scored?/n";
I'm having trouble getting the program to calculate the percentage of times it flipped either heads versus tails. I realize what I currently have doesn't work because above I initialized heads and tails by giving them values of 0, but I'm unsure of how to fix it.
#include <iostream> #include <cstdlib> #include <ctime> using namespace std; int main () { srand(time(0));
I made a simple program to compute the lengths of a triangles sides, but when I enter 30 for angle and 10 for hypotenuse I get the opposite side is -9.880316 and the adjacent is 1.542514.
C programming: I want to creat a program that asks the user to input the integer lengths of three sides of a triangle, and if so whether the triangle is a right-angled, acute or obtuse one. i am having some doubts about the if, else if statements. I never seem to know how and in what order to use them.
Code:
#include <stdio.h> #include <stdlib.h> #include <math.h> int main(int argc, char *argv[]){ int SideA; int SideB; int SideC; }
So I have to write a program to calculate a grade letter into a number.
Letter grades are A, B, C, D, and F, possibly followed by + or –. Their numeric values are 4, 3, 2, 1, and 0. There is no F+ or F–. A + increases the numeric value by 0.3, a – decreases it by 0.3. If the letter grade is illegal (such as "Z"), then your output should be "INVALID LETTER GRADE"; If the combination is illegal (such as "A+" or "F-") then your output should be "INVALID GRADE COMBINATION"
Also the code should look like this Enter your letter grade: C+ Grade value is [2.3]
// Input cout << "Enter your letter grade: "; string s; cin >> s;
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.
#include <iostream> #include <cstdlib> #include <ctime> using std::cout; using std::cin; using std::endl; int dieRoll();
I have an assignment to write a program that will calculate the number of days between two dates (including leap years). We have to read the data from a file and in my current input file I have:
for testing purposes. When I run the program the console runs continuously spouting out "The days between your two dates are 1097." Which would be the correct output for the last set of dates entered, but I need to find out where I've messed up in my main.
#include <iostream> #include <fstream> using namespace std; bool isLeap(int x) { if (x % 400 == 0) {
Write a program that asks the user to enter the number of calories and fat grams in a food item. The program should display the percentage of the calories that come from fat. One gram of fat has 9 calories, so:
(Calories from fat) = (fat grams) * 9
The percentage of calories from fat can be calculated as:
(Calories from fat) / (total calories)
Extend as follow
1. The user first enters from a menu whether it is breakfast (B or b), lunch (L or l) or dinner (D or d). Use character and process by a switch. 2. The threshold for low calorie is different, for breakfast 10%, lunch 20%, dinner 30% (this value has to be assigned to some threshold variable in the above switch). 3. Include validation of menu choice. 4. In case any validation fails, display detailed error and exit the program by calling return 1 or return EXIT_FAILURE 5. Display the % from fat with one decimal digit.
Example 1: What you have to eat: B - breakfast L - lunch D - dinner What you have: C Error: C is not a valid menu choice
Example 2: What you have to eat: B - breakfast L - lunch D - dinner What you have: L How many calories: 600 How many grams of fat: 10 Your food has 15.0% calories from fat It is a low calories food
Process the menu in a switch, setting the threshold as either 10, 20, or 30%. The rest of the program will be the same regardless what was the menu choice.
Incremental development: first do the textbook problem without input validation, then extend with validation, then extend for the additional parts.
my lecture notes had this chunk of code on it. Which was the way to let a user enter not more than 40 different numbers , and save it into an array. The code is as follows :
#include <stdio.h> #define MAX 41 void readData(int num[] , int * count);
[Code]...
In the function readData , why is n being scanned before and during the while loop?
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 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
The instructions: A nutritionist who works for a fitness club facilitate members by evaluating their diets.As part of her evaluation, she asks members for the number of fat grams and carbohydrate grams that they consume in a day. Then, she calculates the number of calories that results from the fat using the following formula:
Calories from fat = fat grams x 9
Next, she calculates the number of calories that result from the carbohydrates using the following formula:
Calories from Carbs = Carbs grams x 4
Create an application that will make these calculations
-DO NOT use global variables -Create two variables in main that will hold the two results -Pass fat and carbs by value, and the result variables by reference -Output in main
The key with what you need to pass is this: Pass fat and carbs by value, and the result variables by reference. This is what I have to far but I don't understand how to "pass by value, and results by variable" ....
#include <iostream> using namespace std; void grams (int); void calories (); int main () { //Get fat and carb grams
So I have a template, part of a larger code, that is designed to calculate the number of multiplications it took to reach a certain number. The problem is, whenever I execute the program, mults is always printing out a strange number, perhaps its actual address.
template <class T> T power3(T x, unsigned int n, unsigned int& mults) { if (n == 0) return 1; if (n == 1) return x; if (n == 2){
5. Four experiments are performed and each experiment produces four test results. The results are tabulated as shown below. Write a program to store these results in a two-dimensional array, A[4][5], then use a nested for-loop to compute the average of the test results for each experiment and store it in the 5th column of the array. Print the array.
6. Using the srand( ) and rand ( ) C++ library functions, fill an array of 1000 numbers with random numbers that have been scaled to the range of 1 to 100 inclusive. Then determine and display the number of random numbers having bvalues between 1 and 50 and the number having values greater than 50. What do you expect the output counts to be?
I have an assignment that I have to make a 3x3 magic square that sums up to 15 on all sides. I can't use arrays, just Loops and If and Else statements.
My first attempt was like this
//Program for printing magic square that sums up to 15.
#include <iostream> using namespace std; int main() { int a, b, c, d, e, f, g, h, i; int r1, r2, r3; int c1, c2, c3;
[Code] .....
I can't think of a way to loop that when it prints out, it will have a sum of 15 on all sides and/or print one of the 8 solution for a 3x3 magic square.
I need to write a program that merges the numbers in two files and writes the results to a third file. The program reads input from two different files and writes the output to a third file. Each input file contains a list of integers in ascending order. After the program is executed, the output file contains the numbers from the two input files in one longer list, also in ascending order. Your program should define a function with three arguments: one for each of the two input file streams and one for the output file stream. The input files should be named numbers1.txt and numbers2.txt, and the output file should be named output.txt.
I have a program that allows the user to enter a specific number of test scores. Based on these test scores, the program should display the average score and calculate how many of the scores were above 90. I have most of it done but I'm having trouble figuring out how to calculate the number of scores that were above 90. What am I doing wrong?
This is my code:
#include <iostream> #include <iomanip> using namespace std; // Function prototypes double average(double*, int); int howManyA(double*, int);
