Visual C++ :: Building A Savings Account Program?
Mar 12, 2014
#include "stdafx.h"
#include <iostream>
#include <iomanip>
#include <cmath>
using namespace std;
[Code].....
I need to modify the program to use annual interests rates of 3%, 4%, and 5%.
After that I need to modify the program to make it so the user enters the dollar amount of the deposit, the interest rate or rates, and the number of years.
I'm a design student at New England Tech but before we can go full design they want to make sure we know for sure if we want to be a designer or a programmer and so we need to take C++ classes

Is there a way to know from a Windows service application (running as a local-system) if a specific logged in interactive user account is configured with a roaming profile? I need this to be compatible with Windows XP SP3.

The project builds on Win32 platform, but not on x64.
Full error message: dllentry.obj : error LNK2001: unresolved external symbol "class CFactoryTemplate * g_Templates" (?g_Templates@@3PAVCFactoryTemplate@@A)
The dllentry.cpp (a DirectShow base class) compiles on both platforms. It contains the external declarations:
extern CFactoryTemplate g_Templates[];
extern int g_cTemplates;
g_Templates[] is then used in two functions:
__control_entrypoint(DllExport) STDAPI DllGetClassObject(__in REFCLSID rClsID,
__in REFIID riid, __deref_out void **pv)
[Code]...
myClass.cpp contains the definitions for the two externals in dllentry.cpp, at top level, just after the includes:
CFactoryTemplate* g_Templates=0;
int g_cTemplates=0;
myClass.cpp also compiles by itself, but the project does not build. I checked all the libraries in the project settings and all seems to be OK, the 64 bit versions are used.
What should I do to make the project build for x64 platform?

I am making this program for a class and it works fine except for the daily interest rate for the checking account is off. The daily interest for the savings computes perfectly. The monthly interest rate for savings is 6% and for checking 3%.
Account.h
#ifndef ACCOUNT_H
#define ACCOUNT_H
#include <iostream>
#include <string>
using namespace std;
const int DAYS_PER_MONTH = 30;

It is suppose to display the message "This Account ID does not exist" but why do I get "segmentation fault"??I was able to compile and run the program so it shouldn't be a problem of the compiler.
Code:
#include <stdio.h>#include <string.h>
struct Account {
char* Account_ID;
char* Account_Type;
char* AccountOwner_FirstName;
char* AccountOwner_LastName;
float* Balance;

I'm trying to do is write a program that fits to a separate test program. The test program provides different size vectors that my function should try and binary search. If the element is found, the function should return 1, and if the element is not found, it returns -1.
Here is the code:
int binSearch(const vector<double> & data, int elem, int & comps) { {
int beg=data[0];
int end=data[data.size()-1];
int mid=(end+beg)/2;
[Code] ......
The problem is that one of the vectors my function is supposed to binary search is a vector of size 0. I tried to throw in an if statement that would return -1 if the size was == 0, but then the program never fully completed and just kept running. So, how can I account for a size 0 vector in my function?

as i am doing an encryption program on a playfair cipher. I am now stuck on a problem on decryption.If my string is helloworld (without a space), it will decrypt normally.However , if my string has a space in between it. Let`s say Hello World, it will not decrypt normally.How do i take into account the space that is in between hello & world?

I am trying to create a NFA from a regular expression. I have a grasp on reading in the regular expression and being able to make a stack from it. The part I am struggling on is mapping the characters in the regular expression to an integer indicating the variables order in the expression. I am just not sure how to go about this.
My code so far...
Code:
#include<stdio.h>
#include<stdlib.h>
#include "stack.h"
int main(void)
{
char expression[80];//array to store regular expression

i built a programming language called jade that right now can only print. i want to add variables to it however. I am going to use a modified bajarne stroustrop calculator to handle expressions (ie will now include string manipulations and such), but I want to build a var class into the program to make it easier for the program. i want variables to act like python variabes, and arrays to act like python associative arrays. Ive scoured different containers, but they only work if the variable isnt an array in my language, because it will only have one type. the only thing i can come up with is a union and 4 overloaded = operators (for bool, int, double, and string) is there a better way to do this?

Basically I want to embed the QGIS canvas widget into a custom application. In order to do that, I need to build QGIS from it's source in order to obtain the devel *.lib, *.dll, *.h, etc. files required. To that result, I am trying to build either version 2.6.* or the current nightly build ~2.7 - 2.8 64 bit version. There is very little documentation on the x64 builds. Not to mention that CMake and I are not the best of friends.
My progress so far:
- Successfully built the extremely out of date nightly build readme instructions of version 0.11 x86
- Partial success in creating CMake output to VS2010, but many required headers were not included such as gqsmapcanvas.h, (So even if I got it building I couldn't use the canvas widget in an application)
*Note I updated the external packages to x64 versions, so it is not an architecture mismatch issue.
I have also had issues with QWT looking for QWT Polar header files, but I suspect this is another issue with the missing headers as most of the errors related to files contained in the original source from GIT.

I am trying to make a for loop that will print out chars in an array while using a #define before main. My problem is that each name has a different amount of chars in it. How do you account for that when you are trying to define a size? For example, I am playing around with the numbers and I just put 7 in for size:
Code:
#include <stdio.h>
#define sizeOf 7
//char personName( char * name[] );
char printName ( char * name[]);

So I'm trying to fill a vector with pointers to account objects.
std::vector<account*> fill_vector() {
std::vector<account*> temp;
std::ifstream s;
std::string str;
s.open("H://account2.dat");
[Code] ....
The accounts have four different types and I am supposed to skip over ones that have an invalid account type and throw an exception:
account* factory(std::string account_code, std::string first_name,
std::string last_name, char type, double balance) {
try {
if(type == 'A') {
simple_account *a = new simple_account(account_code, first_name, last_name, balance);
[Code] .....
My problem is they program will not skip over my rejected accounts.. still adds them to the vector but I cant figure out why!

This exercise should familiarise you with loops, if-then-else statements, and recursion. You will have to design and implement a program that calculates the interest earned on a bank-account. Deadline is the end of Tuesday in week 4.
Interests are compounded; that is, you earn interest on interest. Given a yearly interest rate of say, 6%, you can calculate the total sum available when an initial sum of 4000 pounds is put away for 13 years as follows:
4000 * ( (1 + [6/100])^13 ) = 8531.71 pounds
where the caret symbol denotes 'to the power of'. One way to calculate the power is by repeatedly mulitplying. Ie, you can mulitply 1.06 with 1.06 12 times to calculate 1.06^13.
PART 1
Design and implement a function that raises X to the power Y for a real number X and a positive integer Y. The function must use a while loop.
Design and implement a main program that calculates the sum availble when 1000 pounds has been put away for 25 years with 5 percent interest.
Change the while-loop in the function to a for-loop.

the above pyramid looks like a doom.i.e 1-5 will be in center.1-4(L)1-3(L)1-2(L)1(L) similarly 1-4(R) 1-3(R) 1-2(R) 1(R)
I'm partly successful in building the requirement of the program.but cant able to think the logic for the other half. how can i proceed.below is the code written in c#.
Code:
for (int i = 1; i <= 5; i++)

I would like to initialize a N-dimensional matrix by specifying the dimension N.
To be clearer :
if N=2 I use to do that :
std::vector<std::vector<double>> myMatrix;
if N=3 :
std::vector<std::vector<std::vector<double>>> myMatrix;
and so on...
What I would like is to give N as an argument of a function which construct a N-dimensional empty matrix. Is that possible ?

Making/Building 3D Game Engines, Do I need to know anything related to ART or graphics in order to make them ? I mean, I do know that having a know how about vectors is VERY important, But I am no good at art, I suck. I have thought of getting a separate guy to do the art, as I'm more interested in writing code and then implementing it making use of the art that has been made, I'm just worried if I need to or not need to know anything about sketching or art in order to write a 3D Game engine ?

I have an odd compiling error. My base class is all delcared and read to go. But I could not figure out how to get my sub classes inherit from it. So I had to make everything public. Even inheriting using the protected inheritance thingy, still could not get them to inherit from that base class.
So I compiled the program, and no other class came back with an error. only my base class. Here is the base class:
#include <iostream>
#include <string>
using namespace std;
class Bankaccount {
[Code] .....
The error I'm getting is saying:
error C2143: syntax error : missing ';' before 'using'
Where is there anything needing a semicolon before using?
'Bankaccount' : 'class' type redefinition
see declaration of 'Bankaccount'
Is it saying this because I don't have any private class members?
'Bankaccount' : base class undefined
But it is defined.
What is the issue with this class? And how can I get it to compile and run?

Following function is from a bank account, when new account is created it won't store it in the array or i guess it does but find_acct function wont be able to find it.
find_acct Function:
int findacct(int acctnum_array[], int num_accts, int requested_account) {
for (int index = 0; index < num_accts; index++)
if (acctnum_array[index] == requested_account)
return index;
return -1;

(I'm using visual c++). Write a program that calculates the balance of a savings account at the end of a three month
period. It should ask the user for the starting balance and the annual interest rate. A loop should then iterate once for every month in the period, performing the following:
A) Ask the user for the total amount deposited into the account during that month. Do not accept negative numbers. This amount should be added to the balance.
B) Ask the user for the total amount withdrawn from the account during that month. Do not accept negative numbers or numbers greater than the balance after the deposits for the month have been added in.
C) Calculate the interest for that month. The monthly interest rate is the annual interest rate divided by 12. Multiply the monthly interest rate by the average of that month’s starting and ending balance to get the interest amount for the
month. This amount should be added to the balance.
After the last iteration, the program should display a final report that includes the following information:
• starting balance at the beginning of the three-month period.
• total deposits made during the three months
• total withdrawals made during the three months
• total interest posted to the account during the three months
• final balance.
What I need is to solve that particular problem using a class. Here is the code solved for the problem not using a class:
#include<iostream>
using namespace std;
int main() {
double annulInterestRate,
balance,
monthlyInterestRate,

I am just getting back in to C++ after 10 years not doing any, contributing to an open source project. I'm adding in some functionality and am hitting a road block.
I need to send a multicast packet out on the network that is structured in a certain way. I have the definition, and know what data is going in each byte. I can successfully send a message using multicast, I now just need to send the right message.
I have used a char array to hold the message, as each char represents 1 byte, and I can transmit the array.
I am having trouble putting all of the data in the right place though. If my source data is a string, then I seem to be able to convert it, but if it is a short or int, then I keep getting errors when compiling. Similarly, two of the lines, (version and type) i initially tried using char arrays with a length of one.
Should I be using memcpy or a different function, or even be doing this in a totally different way altogether? This is the code that I am using, along with the packet structure:
//Construct a Zone Query packet
// 4 bytes - Signature "Ohz " = 0x6f, 0x68, 0x7a, 0x20
// 1 bytes - Version = 1
// 1 bytes - Type (0 = Zone Query, 1 = Zone Uri)
// 2 bytes - Entire message length = 12 + zone length
// 4 bytes - Length in bytes of the zone ID
// n bytes - Zone ID to query
[Code] ....
The errors that I get are:
error: invalid conversion from ‘short int’ to ‘const void*’ [-fpermissive]
memcpy(buffer + 6, packetLength, sizeof(packetLength));
^

Let assume that there is an array of integer numbers in the range from 1 to N that are located in the ascending order. For example
#include <iostream>
#include <numeric>
#include <iterator>
int main() {
const size_t N = 20;
[Code] .....
How can it be converted using some one standard algorithm such a way that the resulted sequence would look like
1 3 5 7 9 11 13 15 17 19 20 18 16 14 12 10 8 6 4 2

I am trying to build a destructor that takes an array pointer and outputs part of a private vector and, comparing a string within the objects, overwrites the data in the array with the data in the vector. (vector and array use same class type) It then proceeds as usual.

#include <string>
#include <iomanip>

I'm using a database and im trying to sort a 2D array info[51][10] that contains 51 pieces of records and 10 different fields for each record. And, now I'm trying to sort a desired field in the 2D array alphabetically.
However, the other fields within the same record should be swapped together. (So that the information of the same records stays together).
Also, I am constantly experiencing a run-time error. Sometimes my program works sometimes the whole thing crashes... By opening the code in different folders sometimes works. But the problem is still here. Is there any way to fix this error?
bool swapped =true;
int j=0;
string tmp[10];
swapped =true;
j=0;
