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
[Code] ....
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;

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;

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.]

Example: "abc" -> "abb" -> "aba" should print 2. "aba" will print 0 because it's already a palindrome. "abcd" -> "abcc" -> "abcb" -> "abca" -> "abba" will print 4 because it took 4 changes to make a palindrome.
I'm not too sure how to approach this - I figured out the case where if it's a palindrome (if reversed string is the same) then it'll print out a 0.
int main() {
int number;
cin >> number; //expecting a number for first line user input
for (int i = 0; i < number; i++) {
string str;

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 ;

Write a program that determines the day number (1 to 366) in a year for a date that is provided as input data. As an example, January 1st, 1994, is day 1. December 31, 1993, is day 365. December 31, 1996 is day 366, since 1996 is a leap year. A year is a leap year if it is divisible by four, except that any year divisible by 100 is a leap year only if it is divisible by 40. Your program should accept the month, day, and year as integers. Include a function leap that returns 1 if called with a leap year, 0 otherwise. Extend the requested solution so that your program continues to prompt the user for new dates until a negative year is entered. This is what I have so far.
Code:
#include <stdio.h>
#include <stdbool.h>
int main(void) {
int d,m,y;
int days=0;
int k;

I am unsure how to make this a loop so that it keeps asking for dates?
Working on an assignment and I've hit TWO stumbling blocks. I now have to take the first line from a .txt file and use that number to determine the size of rows to create in my program. I am using fscanf but the program hangs. How can I read in this number, store it and use it in a for loop?
The second issue is after reading this number I have to print each number in the .txt file under a different column. (Note that it skips a line after reading the row count.) The .txt file is set up as follows:
9 1 3 6 4 7 8 8 6 1
The output should look sort of like:
Number 1 3 6 4 7 8 8 6 1
Here's my attempt:
#include <stdio.h>
#include <stdlib.h>
#include <conio.h>
#include <math.h>
typedef struct{
int number;

The program I have is from a tutorial where the user enters two points on a line, and then the program calculates the mid-point and slope.
I want to modify it from it's initial form so that co-ordinates can be input in (x,y) fashion. Right now the user has to enter the x-coordinate, enter a space, and then enter the y-coordinate (lame...)
I saw people using SStream and using that to either write functions to ignore the comma or similar things for converting one file into an array, but not quite what I am trying here.

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;
[code].....
it will not run and im not sure why. I have a couple of errors, but I'm not sure why.
Here is my code.
//Reads input from user to determine different discounts by number of units sold
#include <iostream>
#include <string>
using namespace std;
int main() {
//Declaration and Initialization of variables

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.

if there is a program which i can use to change the name of a variable in a c program for example if i declare a variable like
Code:
int ch;
printf("%d", ch);
Can i later change the name of the ch variable to lets say "number" the code now becomes
Code:
int number;
printf("%d", number);
1. I want to do 2 while at the same moment. Exactly I want one while which is checking the time and it should di something every X second and the other should check something parallel.
2. How i can write the program what i write automaticly into the autorun on every windows pc.
3. Can i change the process-name when the programm started?
4. Can i save my .exe under another name in the autorun
How do i change color of text in the program more than once . rite now i use the code
system ("color 0c");//makes the color of the text red
cout <<"hey";
system ("color 02") //change color to green;
cout<<"only in green ";
it displays both the lines in green not the first in red and second in green.
the problem and my code is at the bottom, the thing is when i checked out what my change was, it was it was like -14.23 which is werid.
Write a program that determines the change that the user should receive after having paid for their purchase. Your program
prompts the user for the number of items purchased
accepts the number of items purchased
prompts the user for the unit price of each item
accepts the unit price of each item
calculates the total purchase price, including HST
outputs the total purchase price
prompts the user for the cash tendered
accepts the amount of cash tendered
calculates the change owed to the user
outputs the number of loonies in the change
outputs the number of cents in the change
You may assume that the user enters valid amounts and tenders enough cash to cover the total purchase price.
The output from your program looks something like:
Enter the number of items : 4
Enter the unit price : 3.15
Purchase price 12.60
HST (13%) 1.64
Total price 14.24
Cash tendered 20.00
Change loonies 5
Change cents 76

Alright so I'm in a computer programming class and I was given the following problem..Write a problem that takes an integer value and multiplies each of the digits together. 4 digit numbers only.
IE; What number do you want to process? 2684
Starting number 2684
End result 384
I know how to start the begging of the program, but i dont understand how to have it to where you can type in all four digits and then it will multiply each number by the other. Also, what are some ways to change the color scheme of the program? I know how it works using CMD, but in Visual C++ its totally different aha.
And for some reason my program pauses (nothing displays, and my cursor changes to the little "loading" cursor thingy) when it hits line 139. That is where I added an additional piece of code that should change the shape of the triangle while the program is running.

I have a program that makes change from an amount. It works fine, but the output is the correct output looped over and over. I have tried everything, but it still doesn't work. For example, a amount of 98 should print
3 quarters
2 dimes
0 nickles
3 pennies
but instead it prints
3 quarters
2 dimes
0 nickels
3 pennies
0 quarters
2 dimes
0 nickels
3 pennies
0 quarters
2 dimes
0 nickels
3 pennies
Why it's doing this?
Code:
#include <iostream>
using namespace std;
int coinscount(int& amount, int value) {
int tracker = 0;
int amountdimes = amount;

I've made an effort for three days to write this code. But, my brain has stopped now. I wrote code to find the status of the game (win, loss or tie). However, I can't determine the tie status of the game. Tie status is the problem
View 5 Replies View RelatedI'm working with arrays that might have NULL bytes in them and I'm wondering how to determine the length of the array or store it somewhere with the array (strlen() won't work because of the NULL, right?).
I've found advice like store the length of the array in the first byte of the array, but since sizeof(size_t) is 8 should I leave the first 8 bytes for the length?
Would it be better do define my own structure which would store the array and its length? What's the usual way these things are handled in practice?
I would like to make a handler for input events, but not be required to define all the functions.For example, if I had
void mouseDown(int button,vec2 pos);
void mouseUp(int button,vec2 pos);
static void mouseStateHandle(int button,int state,int x,int y) {
switch(state){
case DOWN:

in the 'mouseStateHandle' function? I don't know enough about C++ to be able to come up with a solution.
I am making an eVoting program which takes input from .txt file and outputs in the same .txt file. I need to ask the user to enter the candidate they wish to vote and then read the previous tally from the .txt file and add one to it. The problem is determining the numbers in a .txt file and adding one to it.
For example voting_Tally.txt contains:
Bloomberg 1234
Bill De Blasio 6789
How would it be possible to first determine the name and then add one to their tally. For Example:
Bloomberg 1235
Bill De Blasio 6790
How can I determine whether there is a collision between 2 meshes? I'd just like to see if one mesh is inside another.
