C++ :: Getting Optimal Change In Cents
Sep 4, 2014
On one of my assignments I have to find the optimal change. For example, if I were to have 70 cents and had only quarters, dimes and pennies, the best way to receive change using less coins all together would be 2 quarters and 2 dimes (4 coins all together should be displayed).
All in all, I understand my assignment, however there is something I don't know how to do (or can't recall how to) and that is finding the the highest number in an array to use in a function and be able to compare it.
#include<iostream>
using namespace std;
//function in which amount = money, changeArray is the array where money is stored,
//and numCoins the amount of coin types there are available in the array
int optimalChange(int amount, int * changeArray, int numCoins) {
[Code] .....
What I'm stuck with, is that I don't remember how to get the highest number from the array that way I can compare it with the total amount when I'm building my function. Also, the function has to call itself recursively.

I want to write a command line parsing library that is very flexible in terms of parsing style but I'm not able to design a mechanism that satisfies this requirements.
Generally i want to have a class that contains all the necessary information about how the command line has to be parsed.
Code:
// draft
class style {
public:
enum class type { // the basic style type
[Code] ....
Need completing the draft shown above, because for every basic style type there is an own set of extensions that applies only to this one specific style type.
Code:
// how a style object should be created
style parsing_style(style::type::posix, style::extension::gnu|style::extension::subcommand);
How to design the class. (using c++11 features like std::enable_if is fine)

I haven't actually learned how to use arrays yet but I know the basic principle of it and decided to try and implement one to improve my code. I'm sure the thing is a bug ridden mess but I would particularly like to point your attention to the function sortDenomination(). Is what I am trying to do in the loop possible?
The reason why I want to do it this way and not with if statements for each denomination is because I can then easily apply this to the second part of the assignment which sees us split a double into dollars and cents and then process each separately. All I would have to differ for each is change the money_loop variable to include the last two denominations in the array.
Code:
#include <stdio.h>
/*Reads cents input from the user.*/
void getCents(int &read_cents) {
printf("Please enter the amount of cents between 5-95:

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 ;
[code]....

How to declare the values of the the dimes and quarters in my program. The purpose of it is to add up the total number in cents while at the same time making sure the program is universal to be used with different numbers.
Here is my code.
/*Take the number of dimes and quarters and get the total ammount of cents*/
#include <iostream>
using namespace std;
int main ( ) {
int dimes,quarters,result,amount_1,amount_2
int result;

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;
[code]...

how to use a keyboard. I have the program running now in Dev-C++, but the standard display letters on the monitor are small and sort of boring.Within a C program, is there a way to change the font to something stylish? Enlarge the letters? Change the color from letter to letter?
In the old days, there was graphics.h, but that isn't included now, and I would prefer to use some modern extension. I'd like to write it on Win7, then move it to Linux on Raspberry Pi. It would be nice to avoid a full-scale graphics system like OpenGL.

I am working on a program that is supposed to do I/O file streaming. I dont know if I can properly explain how its supposed to work but I have found the error on my code, I just dont know WHY the error is happening? If you look in the while loop, count changes values like it should, but MOVE and TIP doesnt. Count starts at value 2. So move is 108. Then count becomes 4, but move stays at 108?
tring rec;
fstream myfile("File.txt", ios::in | ios::out);
myfile.seekg(myfile.tellg(), ios::beg);
myfile.seekp(51, ios::beg);
[Code]....
The lines of code im getting errors on is
int move = count * 54;
int tip = move + 51;
Move wont change its value? It stays 108, causing this infinite while loop. Where is the error in my code to cause move to not change values like count does?
I seem to be struggling with I/O File streaming :(

i have my basic C program here (i'm new to C language):
Code:
#include <stdio.h>
int main()
{
int grade;
int A=0;
int B=0;
int C=0;
int D=0;
int E=0;
[Code]....
As you can see, it's only for counting how many students got the grades from A to E, but the problem is that i need to change it from numbers into asterisk
for example: 4 students got the grade A, and 3 students got the grade B
instead of displaying
A=4
B=3
i want it to display
A=****
B=***

I have installed VS 2010 and VS 2012. VS 2012 uses SqlServer CE 3.5 and VS 2012 uses SqlServer CE 4.0.The problem is that when a project uses a 3.5 file it tries to open it with 4.0 even if the app.config says to use the 3.5 provider. The version of the assembly is pulled right out of the GAC. I uninstalled 4.0 and the reference auto updated its version to 3.5.1. However after installing 4.0 again it changes to 4.0. The error I am getting is that 4.0 cannot open a 3.5 file....they changed the file format from 3.5 to 4.0 and they are not compatible.

For particular assignment, I am asked to evaluate data from an inputfile, let it be named "infile.dat". Next, it is required to output to this same file, but with the name of this file altered to reflect the changes of data. For example, if I want to change the original file name to "changed_infile.dat.altered" by adding the "changed_" prefix and ".altered" suffix, how could this be done?
From my understanding, there are no functions in <fstream> that could change the file name. However, there is a rename function in <stdio>, but it's not exactly what I am looking for because I want to append a prefix and suffix to this existing inputfile name. Although I could apply a brute force method by simply doing rename("infile.dat", "changed_infile.dat.altered"), I want to have my program to work with various input files of different names.

I am building a tamagotchi like application/game. As for the leveling up and changing of character I am using a char value so that the icon can change as the character progresses.
Due to the fact that the value for level is changing I need it to also change for what is being used for the case statements
I know I cant use variables in case statements because I have tried every way I can think of.
The code is
switch(Area[y][x])
{
case '*':
Area[y][x] = Level;
break;
case 1:
{
CODE
}
}
Where I have the case 1 I need it to change as level increases (as level is starting at 1)
