Mar 8, 2014Write a program in C that will allow a user to enter an amount of money, then display the least number of coins and the value of each coin required to make up that amount. The twist to this program is the introduction of a new coin - the jonnie (value = $1.26). Therefore, the coins available for your calculations are: Twonies, Loonies, Jonnies, Quarters, Dimes, Nickels and Pennies. You can assume the amount of money user enters will be less than $100.00.
User enters $4.53. Your output should be:
The least number of coins required to make up $4.53 is 4. The coins needed are:
1 Toonie $2.00
2 Jonnies $2.52
1 Penny $0.01
$4.53
I'm wondering if i'm close. I'm stuck on what to do for the output. This is what i have so far.
Code:
//Start
#include <stdio.h>
int main() {
//Get user input for amount of money
//Input
int i;
//Store input from user

C++ :: Remove Char Without Space From String
Aug 6, 2013I need to remove a char from string that found ;
For example : string- abcdfe
the char ch is - c
and the return new string is : abdfe.
I did as follow:
void removeChar(char string2[SIZE], char ch) {
char input= 'a'; // for example replace something
int i=0;
if(string2[i]== ch && string2[i]!='/0') {
string2[i]= input;
}
i++;
}
and in the main : I only called to this function above and print string.

C++ :: How To Read Input Of Arbitrary Amount Of Numbers Instead Of Specific Amount
Feb 25, 2015I'm trying to make a program that allows the user to input an arbitrary amount of numbers and finding the largest of all the inputs but I keep having problems with the output.
javascript:tx('
#include <iostream>
using namespace std;
//******************************************
//CLASS COMPARATOR
//******************************************
class comparator {
public:
comparator();
[Code] .....
And regardless of what numbers I enter, I always get the output of 10. Also I got the EOF idea from my textbook so if there is a better way of doing this I'd like to hear it. I don't know any clear ways that looks nice to end the while loop when the user doesn't have any more numbers to enter.
C++ :: Reserve Space For Array?
Oct 12, 2013In my code I have a template class.
In the contructor, I create a new array arrray.
A pointer to this array is saved as an attribute.
The purpose of this attribute is that I should be able to call the array from within another function be typing *p or *(p+1) etc.
The only thing I forgot is that the array doesn't exist anymore when the constructor is done, right?
This means the space is no longer reserved for this array and the space is used for other things.
Is there a way to keep the array space reserved (even when the array does not exist anymore at the end of the function)?

C++ :: Structures - How To Update Space Ship Position In Array
Apr 7, 2013I want to do this but do not know exactly how to do it:
Create an array of space ship objects and write a program that continually updates their positions until they all go off the screen. Assume that the size of the screen is 1024 pixels by 768 pixels.
I have begun to write a bit code but the problem is when you want to see the space ship moving step for step on the screen I do not know how to create the ship visible so you can see it is moving. Here's my code so far
Code:
#include <iostream>
using namespace std;
struct SpaceShips

C++ :: Comparing Char Array To Char Always Returns True
Dec 23, 2014I've made a code to check whether or not a save file has been created correctly, but for some reason it always returns this line: readdata[qa]=='1' as true. in which qa is the counter I use in a for loop and readdata is a character array consisting of 50 characters that are either 0, 1 or 2.
this is the entire code:
#include <iostream>
#include <fstream>
#include <string>
using namespace std;

at first is also went wrong at line 22 and also returned that as true, but then I added brackets and it worked.
C++ :: Concatenate Two Char Arrays Into Single Char Array?
Sep 29, 2014I am trying to concatenate two words from a file together. ex: "joe" "bob" into "joe bob". I have provided my function(s) below. I am somehow obtaining the terminal readout below. I have initialized my memory (I have to use dynamic, dont suggest fixing that). I have set up my char arrays (I HAVE TO USE CHAR ARRAYS (c-style string) DONT SUGGEST STRINGS) I know this is a weird way to do this, but it is academic. I am currently stuck. My file will read in to my tempfName and templName and will concatenate correctly into my tempName, but I am unable to correctly get into my (*playerPtr).name.
/* this is my terminal readout
joe bob
<- nothing is put into (*playerPtr).name, why not?

May 28, 2013I wrote this simplified version of a program i am writing that parses data in UDP packets. In the process of doing so i pretty much answered all my questions and fix all the problems i was having.
decodeSystemMap function will be in loop, and will proccess packets that have mostly the same data, only a few items will be added or changed or deleted.
whats the best way to check if there are any new, deleted, or removed items in the packet and only modify those?

C++ :: How To Get Amount Of RAM Available On PC
Mar 6, 2013I bet there's a simple function that can return the amount of RAM available on the computer, or perhaps the total RAM on the chip.
Basically I want a way of making sure my program never tries to allocate memory when it can't... I know that Windows should stop this happening anyway but I want to make sure the program can take care of certain things if it happens.

C++ :: Char Array To String
Oct 19, 2013I have some code:
char cHomeTeamFaceOffsPercentageWon[100];
memcpy(cHomeTeamFaceOffsPercentageWon,cSqlHomeTeamFaceOffsPercentageWon,100);
After this, for example, cHomeTeamFaceOffsPercentageWon is, "29%".
Then, I use
std::string szwPercentageWon = std::string(cHomeTeamFaceOffsPercentageWon);
szwPercentageWon is then, "2". Shouldn't this convert correctly, to "29%" as well.
Or is there something I'm missing? Maybe the termination character, or something.

C++ :: Assigning Char To Array?

int grade;
char A, B, C, D, F;
cout << "Enter da grade" << endl;
cin >> grade;

A, B, C, D, and F won't transfer to the array, thus giving me the uninitialized variable error in microsoft visual studio 2010.
