C++ :: Struct Coinbox - Make Change For Input
Mar 14, 2013
I need writing the function that makes change for an input number. Input a bunch of quarters, dimes, nickels, pennies, then in MAKE_CHANGE the amount per say (184) is input. So for 184cents, runs through quarters first using the quarters we have in the coinbox, and then goes to the next currency for the remaining 9cents
(184/25=7 184%25=9).
#include <cstdlib>
#include <iostream>
using namespace std;
struct coinbox {
int quarters;
int dimes;

I have a linked list where each node contains a pointer to a string, I'm treating the linked list as a text file and each node/string contains each line in the text file.
I have all of that working, but now I need to create a switchLine function that takes in the two line numbers and I need to switch those lines in the text file. I initially thought of switching the pointers to each the next node in the linked list such that the node order changes, but I then realized how much work that would actually take when you need to consider so many cases. So I instead thought of changing the pointers to strings. If I want to switch the 2nd and 3rd line, then I'd want to have the 2nd node in the list have its char * pointer point to the memory position that the 3rd node's char pointer points to, and vice versa.

I've been trying to research this error message but I haven't been able to find much that pertains to the simple code I have.
Below it the first part of my c++ program that includes everything that I have changed before the error appeared. It seems to be centered around changing the void function at the end
#include <iostream>
#include <fstream>
#include <string>
#include <iomanip>
#include <climits>
using namespace std;
const int NUM_STUDENTS = 10;
const int NUM_SCORES = 5;
void getStudentInfo(string[], int[][NUM_SCORES], float[], char[]);
[code].....
The final line was originally
void getStudentInfo(string sn[], int ss[][NUM_SCORES], float sa[], char sg[]) {

I'm trying to determine the number of times I have to change each specific character in a string to make it a palindrome. You can only change a character one at a time from the end.
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;

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 need to convert some input values in c#
for example if input is 0.0 then it should take value as 63.
0.5 as 62
1.0 as 61
1.5 as 60
2.0 as 59
2.5 as 58
3.0 as 57
:
:
:
:
28.5 as 3
29.0 as 2
29.5 as 1
30.0 as 0
now maybe I can define it in enum and use it but before doing that i wanna try if i can put an equation instead of defining these values into memory.

Player is given choice of x number of Races This choice changes the player's base stats. Then player is given a choice of x number of Classes (archer, warrior, etc.) This choice determines how the player's stats will change upon leveling up.

I need to create a list of all members of a struct using the sturct definition as input. The struct is NOT part of the program, but is the input to the program.
The struct that I am using changes over time as features are added. I need the complete, fully qualified field names to then generate a table with all names with their offsets, type and length.
This information then allows me to create readers of the data that will run on different architectures, compilers and operating systems.
The struct currently has 800+ lines and uses typedef and embedded structs.
Perhaps this could be done creating LEX, YACC, Perl, SED, AWK or other language system.

I'm working on a code that needs to loop a switch case back to the beginning after a certain input is entered.
ex) Code:
printf("Select an option);
printf("1. Play game");
printf("2. Status");
printf("3. Exit");
scanf("%i", &userinput);
switch(userinput);
[Code]...
For my program, I want option 2 to display something, then loop back to "select and option" after the user presses enter. How would I write that? Would i use a while? do while?

I have to make a program that takes a number input from the user and prints the corresponding fibonacci sequence number. For example, for the input of 3, it should print 2 since the third term in the fibonacci sequence is 2.
I am not sure how to do this so for my attempt, I used the formula found in this website. A Formula for the nth Fibonacci number
Here is the program so far. It doesn't produce the correct output.
Code:
#include <stdio.h>
#include "genlib.h"
#include "simpio.h"
#include "math.h"

I need to write a program to make the user input some text, and the first letter of each word has to be uppercase. (have to use while loops)
So for example lets say the user inputs:
i lOvE pRoGrAmMiNg
The output needs to be:
I Love Programming
Code: int main()
{
char c, lower_c;
printf("Enter Text");
while (c != '' && c >= 0)
{
if (c >= 'A' && c <= 'Z')
lower_c = c + 32;
else
lower_c = c;
[Code]...
I have started this code by making the letters lowercase (I don't know if this was the right way to approach this, ). I am not sure how proceed after this step, the step of making the first letter uppercase. (PS for the program, loops should be while loops)

I've reached a point in "Jumping into C++" where I need to make a program that converts input numbers into their word equivalent.
So far I've made it work for numbers 0-9999. I've tried implementing 10000-99999 but there are problems with the order of the words printed (57865 would print fifty thousand seven thousand eight hundred sixty five). But besides that, the program is absolutely enormous (for me) and I'm wondering if it can be shortened. Keep in mind I can only use loops and if statements so far. Here it is:
Code:
#include <iostream>
#include <string>
void extras(int e);
void digits(int x);
void tens(int xx);
void hundreds(int xxx);
void thousands(int xxxx);
//void tens_of_thousands(long xxxxx);

I want the numbers to be put into the array until it hits a new line. Maximum number of numbers is 1000. What can I replace that while loop with to stop it from reading further into the input file?
Code:
while (input != '
'){
for(i=0; i<1000; i++)
fscanf(ifp, "%lf", &auctions_prices[i]);

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 was attempting something weired with address to move data around when I discovered that the size of the array is not what I expected. I am passing this structure as &Users to a function that declares it as a void *, then I can deal with chunks of data (memmove) and not have to worry about index or things like that. However...sizeof is returning something I do not understand.

I just read and have known for a while that classes are private (members and inheritance) by default and structs are public. But my question then comes what if.. a struct inheriting from a class or a class inheriting from a struct?
