C++ :: Program To Simulate Coin Toss
Nov 14, 2013
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.]

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;

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

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 {
string line ;

Create a line class using a linked list that acts as a queue (first in, first out) both enqueue and dequeue. Complete the line class so that customers can be added or removed from the line. Implement the line as a linked list of customer objects that you have developed yourself or use the vector class.

I have not been using pointers that long i most of my stuff has not needed them but now they do i need to learn how to use them more. I'm writing a program that simulates the squares most landed on(for fun) and i cant get a method to work because of an array pointer.
The error is no matching function for call to 'GameLoop::Loop(int, int (*)[4])'
Here is the latest version of the code. I've been editing a lot of things so there might be some stupid errors but I've tring everything.
rolling.h and rolling.cpp are just some dice function they are working perfect.
main.cpp
#include <iostream>
#include "Rolling.h"
#include "GameLoop.h"
Rolling Roll;
GameLoop Game;

Write a program to simulate a deck of 52 playing cards.
Represent your deck as a 2D Array where the value in the cell is the position of the card in the deck. Represent the names for the suits and faces as an array of Strings.
Write an algorithm to shuffle the deck.
Display the deck. For Example:
1 Jack of Spades
2 Deuce of Diamonds
3 Three of Diamonds
4 King of Spades
5 Eight of Clubs
6 King of Diamonds
7 Six of Clubs
8 Six of Spades
9 Eight of Hearts
Deal two hands of five cards each. For Example:
****** HAND 1 ******
Jack of Spades
Three of Diamonds
Eight of Clubs
Six of Clubs
Eight of Hearts
...
Below is what I have so far. Dealing two hands and displaying it. How would I be able to do that?
#include <iostream>
#include <ctime>
#include <string>
using namespace std;
void shuffle(int[][2]);
int main()
{
int j,deck[52][2];

The problem: I am trying to connect the 1d arrays to the 2d arrays. Right now when I write: cout << deck[3][5] << endl; The output answer is 45. How do I populate the 2d array with the 1d arrays so that when I cout deck[3][5] I get it to say "Six of Spades"?

Consider a program that simulates a card game, with multiple player hands and a deck to draw from. Each hand can use an array to represent the cards it contains; sometimes it is useful to also declare an additional variable for each hand (or deck) indicating exactly how many cards are present.
1) Describe a simple function that would manipulate both the array representing a hand and the number indicating the size of the hand.
2) Describe a simple function that might be able to manipulate the array without referring to the hand size variable at all.
3) Generally, if the array was passed as a parameter to a function, how often would the hand size be included as a parameter?

I have an assignment where i am required to code up in C, a program to simulate a taxi rank that is implemented as a queue via an array that can hold up to a maximum of six taxis.When a taxi arrives, it joins the rear of the queue. When a taxi departs, the first taxi in the rank is used and its departure is logged.A "rolling menu" comprising integer codes as specified below is used until 0 is entered to exit the simulation. I've done this stage but now the next stage is asking me to implement the queue as a linked list. what the difference is between an array and a linked list and what is a linked list?

I'm just starting to learn C++ with Jumping into C++. In Chapter 9, we are asked to create a coining flipping program. 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:
Code:
#include <iostream>
#include <ctime>
#include <cstdlib>
using namespace std;
int rand_num;

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 <cstdlib>
#include <ctime>
using namespace std;
int main () {
srand(time(0));

My coin/money change code works when there can be an exact change each time, i.e. when the 1 cent option is available. However, when the change options are only $10, $5, $1, 25 cents and 10 cents, it does not give me what I want for instance, I wanted to get change for $237.80, I was expecting to get:
23 10's, one 5, two 1's and 8 dimes. However, the code below is giving me 23 10's, one 5, two 1's and 3 quarters (there is no option left for the 5 remaining cents).how to fix it?
Code:
#include<iostream>
#include<algorithm>
#include<vector>
using namespace std;
void change(double cents, int a[]);
int main() {
double Dollars;
double cents;

have udp server-client application written in C. On the client side packet loss is detected using recvfrom function and sequence numbers of packets. How can I now simulate dropped packet's on the client side, for example if server is sending 1000 packet I want to drop 20% of them? I want to do this in the code, not for example using ip tables or WANEM or something like that. And one more thing, I have few clients and I want that they can dropped different packets, not the same one.
Code:
while(1){
nbytes = recvfrom(socket, buffer, MAX_SIZE, 0, (struct sockaddr *) &srv_addr, &addrlen);
if (nbytes != -1) {
// packet is received
}else{
//packet is not received
}
}

I am writing a piece of code that simulates a random walk in 2 dimensions (an object chooses whether to move up, down, left or right randomly). I would like the program to run the simulation for many objects at the same time. The way i have written it means that for every object i add the code becomes about 40 lines longer. Any method that would simplify the code so that i could have many objects but not pages and pages of code.
#include <ctime>
#include <cstdlib>
#include<iostream>
#include<cmath>
#include<iomanip>
#include<fstream>
using namespace std;

I want to write a c++ code that due the structure of file space allocation,Simulates file system with 2*n array. Each column represents a sector. The first row is for storing files And second row holds the address of the next sector (Number of columns). And With each click on keyboard Create a file with random size and automatically find Appropriate sectors by using disk allocation method (or index allocation)... Also File names should be asked from user... And we should have file table Where the starting address of each sector,file extension and file size is given..

So this code compiles without any problem but it is not producing the correct output. I know there's a problem in either my getBlock or putBlock functions but I can't see it.
Currently the output is "Should be 32 1s: "
"Should be 32 2s: "
There should be 32 1s and 32 2s and nothing is coming out.

I am trying to simulate memory in C. I want to create a structure in C that will hold a 8bit opcode and a 32bit memory address. This would simulate a 40 bit instruction for my simulator.
I read in an old book that packed structs could be used for this to not waste space. What are the draw backs for using this? I am not worried about wasting space, but just looking for a simple way to access the memory instructions. Below is a sample of the structure that I want to use.
struct memory_area {
unsigned int opcode:8;
unsigned int address:32;
};

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 make a random number generator to simulate a critical hit if the number generated is from 0-critical amount. However, every time i run the code, despite being within the parameters set by the if statements, it always runs through as a critical hit and never a regular hit.
#include <iostream>
#include <iomanip>
#include <ctime>
#include <cstdlib>
using namespace std;
int main(){
srand((unsigned)time(0));

Write a program that simulates an adding machine. When a zero is entered it should print the subtotal of all the numbers entered from the last zero that was entered and reset the subtotal. When two consecutive zeroes are entered it should print the total (not the subtotal) of all the numbers entered and terminate the program. Example:
1
2
3
0
subtotal 6
4
5
-2
0
subtotal 7
8
0
subtotal 8
0
total 21
Be careful this program needs a bit more thought than you might think at first. To get full credit you must make sure it also works for the 0 - 0 case. Example:
0
subtotal 0
0
total 0
The problem is, after I enter the integers and type 0, it shows the subtotal which is what I want; however, when I type more integers and type another 0 to see the subtotal again, it shows the total instead. The subtotal should reset whenever a single 0 is typed and the total should only show when two 0's are inputted simultaneously. Also, after the user enters two 0's simultaneously and views their total, I want the program to exit by saying "press any key to exit." Is there a special name for that to happen? Here is my code:
#include "stdafx.h"
#include <iostream>
using namespace std;
int main() {
int subtotal = 0, total = 0, number = 0;
bool input_zero = false;

I am supposed to create a program that simulates a random walk that starts with position 0. If its odd it moves to the right (add one) if the random number is even it moves to the left (subtract 1).
#include<iostream>
#include<iomanip>
using namespace std;
void main() {
int num1, num2, num3, num4, i, rs = 12345 ;
cout << " Please enter the number iterations to be executed: ";
[Code] ....
I'm getting an error when I try to run the program: error C2106: '=' : left operand must be l-value. So I don't even know if what I have is right.
