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.

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.

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

For example, to calculate GPA, we add all the grade point of a course and divide by the number of courses we are taking. How do I create a program in such a way that when the user enters grade point for two courses, it will add the grade points for the two course and divide by 2. And if another user enters grade points for six courses, it adds the grade points and divides by 6.

My code runs, but I can't figure out why it keeps printing tails. Not very random. My thing was that I can pick heads if the random number generated from rand() is even, and tails if it is odd. But it just keeps printing tails.
Here is my code:

I am currently using Xcode on a Mac to compile a c++ program. My class uses Codeblocks and I am having issues with the variable names and commands.
The assignment is to write a program that calculates the quarters, dimes, nickels, and pennies needed to input the amount of money. We have to apply the largest value coins first and use modulus for the remainder.
the input for turning in is: 398
This is idea I am getting...
#include <iostream>
int input;
int quarters, dimes, nickels, pennies;
cout<<"Enter dollar amount: ";
cin>> input;
quarters = inputquarters/.25;
[Code] ....
I have a current assignment for C++ involving us to make a program to determine coin change for example if you input the number 127 you would need 2 half dollars 1quarter and 2 pennies I have no way how to program this.
This is my code that doesn't do what i want it to
#include <iostream>
using namespace std;
int main ( ) {
float change;
int half_dollars, quarters, dimes, nickels, pennies; // declare variables

Write a program that simulates coin tossing. For each toss of the coin, the program should print Heads or Tails. Let the program toss the coin 100 times and count the number of times each side of the coin appears. Print the results. The program should call a separate function flip that takes no arguments and returns 0 for tails and 1 for heads. [Note: If the program realistically simulates the coin tossing, then each side of the coin should appear approximately half the time.]

Code: a.b "a"
is the actual object (not a memory location) and "b" is the member. I also understand the arrow to mean:
Code: a->b "a"
is a pointer to a struct and "b" is it's member so "a" is dereferenced then "b" is given.

I'm currently working on a program to take the user's input as DDDD.CC and then converting it to the least amount of coins using quarters, dimes, nickels, and pennies. I was told to not use any doubles or floats as they would produce errors. And supposed to the use the library function atoi() after I take the input user's amount as a string to convert it into an integer.
So far the string input has worked and it produced the right number of quarters but it leaves off the cents. For example, I put in 352.23 and it gives the right amount of quarters but leaves off the 23 cents.here's my code:
#include <iostream> // Allows the program to perform input and output
#include <stdlib.h> // Atoi
#include <string>
using namespace std ; // Enables a program to use all the names in any Standard C++ header
int main() // Start of program execution {

I tried to keep the coding style as similar as possible. I tested these with 4 million (4x1024x1024) 64 bit unsigned integers, Visual Studio 2005, 64 bit mode, Win XP X64, Intel 2600K 3.4ghz cpu. The average time for top down = 3.7 seconds, bottom up = 3.5 seconds.

I am in a position to choose between function pointers and subclassed objects. To make it clear, say I have to notify some object of some action (a timer for example); refer to the following two choices (a very basic code for demo purposes):
Version 1
typedef void TimerCallback(void *args);
class Timer{
public:
Timer();

Version 2:
class TimerTask{
public:
TimerTask();
virtual ~TimerTask();

which one is the standard C++ way and which one is efficient?
there is a performance difference (e.g access time, speed, ...) between allocating static memory vs dynamic memory?
For example, if am reading data from a file, and storing them inside a huge buffer, what would be the differences between storing these data inside a static buffer vs a dynamic one?
Using integers faster than using floating points? Or more precise: what do you estimate as the chance that writing a custom floating point class is worth the effort?
I need to examine some C++ code for an ARM7 or ARM9 processor. Instead of using floating points, the coder had chosen to use integers only. To be able to fake floating points, a custom class was written. The coder states that he avoids using floating points as these are much how much slower. "Have you measured this?", I asked. "No, but it is known to be so", he replied.
Google taught me that most people state integers are faster than using doubles, because their operations (addition, multiplication) take less assembler instructions. But if you need those floating points, what do you estimate as the chance that writing a custom floating point class is worth the effort?
Basically what are the advantages and disadvantages of having an array implementation vs linked list implementation for a stack?
View 1 Replies View RelatedA while ago i was asked to write a program for a class that used a "Double ended queue with a current-position marker."
An example of some of the functions that i created are:
boolean atFirst() // Returns true if first element is current. Pre: !isEmpty().
boolean atLast() // Returns true if last element is current. Pre: !isEmpty().
void makeEmpty() // Sets this List to the empty state. Post: isEmpty().
void moveFirst() // Sets current marker to first element.
void movePrev() // Moves current marker one step toward first element.
void moveNext() // Moves current marker one step toward last element.
void insertBeforeFirst(int data) // Inserts new element before first element.
My question is whether a double ended queue with pointer is the same thing as a "doubly linked list" in this case. The terminology is throwing me of a little. If the two concepts are different, how is a doubly linked list different?

I want to update a file but I want to show the percentage when it is being updated. How can I do this? Do I need to use threads?
View 2 Replies View RelatedWrite 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.
