C :: Not Using Structures For Project
Apr 5, 2013
I have to do a project for Programming and he said in quotes
"Programming exercise 10.6: the programming project is as described, except do not represent the points using structures.
Assume, as known, the ten (x,y)-values corresponding to x=0.0, 0.1, 0.3, 0.45 ..etc and use y-values from the
function xsin(x); as in (x,y)=(x, xsin(x)) = (0.3, 0.3sin(0.3)).
Use value n+1=10, so the LaGrange polynomial will be order = 9."
What does it mean to not represent the points using structures??

Write a program that uses a record structure to store a Student Name, Student ID, Test Scores, Average Test Score, and Grade. The program should keep a list of test scores for a group of 6 students. The program should ask for the name, ID, and four test scores for each student. Then the average test score should be calculated and stored. The course grade should be based on the following scale:
Average Test Score Course Grade
------------------ ------------
90 - 100 A
80 - 89 B
70 - 79 C
60 - 69 D
59 or below F
A table should be displayed on the screen listing each student's name, ID, average test score, and course grade. Implement with functions.
My code runs but it isnt returning anything (readable/correct) and i have no clue why. This is what i have so far:
#include <iostream>
using namespace std;
const int columns = 4;
struct StuRec //user defined datatype {
int id[6];
char names[6][20];
[Code] .....
it compiles completely but at the end instead of showing the student name ID average score and class grade it shows.... [URL] .....

I have a project which does a specific thing, like an open file dialog.
I would like to open it in a different project on a click of a button.
Also, It has a different namespace.
I'm guessing that it would involve a "using" statement to add the namespace And I will have to add reference to an *.exe or *.dll -> I'll have to look up how to make a *.dll, I know where the *.exe file is.
I have searched for a different things on Google, but I don't think that I am looking for the correct phrase (which is always frustrating...)

At the moment im trying to integrate an dll in my project (first time).
I copy the lib and dll to my project-directory and the header to my include path.
Now i get a linker error:
1>LINK : fatal error LNK1181: cannot open input file "libWebSvcTx.obj"
the dll calls libWebSvcTx.dll.
I insert the libWebSvcTx.lib to the Dependencies.
Don't know whats the mention of the output and how to avoid it...

I'm pretty new to C++ and I'm on Binary Trees in "Jumping into C++"! I've just created a DLL project on Code::Blocks, and I cannot get it to build and run: "You must select a host application to "run" a library..." is the message that I'm getting when I run the main code file. It's had no changes to it (except for a few extra, unnecessary line feeds), and it's the file which Code::Blocks generates on a DLL project.

I am writing a program that has many header files and their corresponding implementation files. I collected all the header files in a folder and did same for the implementation files into another folder. I'm using the Dev C++ IDE; I could add the files one by one to the project. Instead of doing this however, I tried adding the two folders to the project; but, the project did not compile!! The compiler could not find the files resident in each of the folders!
How I can add the folders to the project so that the internal files are visible to the compiler; or do I have to go the longer route of adding the internal files individually??

I am building a log4net wrapper project where I reference log4net.dll. When calling this code through a static instance to log messages the new project also wants me to reference log4net.dll even though I have a reference to my logging project which in turn has the reference..

Ok, for my Sunday homework I have to find the next day of the year using structures. Now, I can get the structure to read the entered date (tested that with a simple scanf to printf entered data), but I need to get it to be able to tell that it is the end of the month and print out the next month when necessary. Here is what I got so far:
Code:
//Cameron Taylor
#include <stdio.h>
struct Date{
int month;
int day;
int year;
[Code] ....
As you can see, I am trying to use an array for the max day of each month (excluding Leap Year for now).
Where I use the entered month to = 'i'. Then I use 'i' as the position in the array to see if next.day is = to the max day of that position of the array.
I am having no compiler issues with GCC using -w or -Wall, but after entering the current day the program stops working and doesn't go beyond the input.
commiedic@localhost Project18$ gcc -o -Wall Exercise4.c
commiedic@localhost Project18$ gcc -o -w Exercise4.c
commiedic@localhost Project18$ gcc -w Exercise4.c
commiedic@localhost Project18$ make Exercise4
make: `Exercise4' is up to date.

Here is the problem:"Write a program that converts a number entered in Roman numerals to a positive integer. Your program should consist of a class, say, romanType. An object of type romanType should do the following:
a. Store the number as a positive integer.
b. Convert and store the number as a positive integer.
c. Print the number as a Roman numeral or positive integer as requested by the user.
The integer values of the Roman numerals are:
M 1000
D 500
C 100
L 50
X 10
V 5
I 1
d. Test your program using the following Roman numerals: MCXIV, CCCLIX, MDCLXVI."I'm doing the best I can to understand the concept of the class. Here is what I have (which is not much thus far, and nowhere near correct I'm sure).
#include<iostream>
#include<iomanip>
using namespace std;
class romanType {
public:
void getRoman();

I am currently working on a custom "Array" class for a project, and I have run into an error I don't quite understand the source of. The relevant code is as follows:
template<typename T> class Array {
private:
T errValCopy;
public:
T __errVal__;
uint16 __size__;
T* __ptr__;
Array(const T& errorValue);
[Code] ....
When I try to run the following code:
Array<Array<int>> a(Array<int>(-1));
The error log tells me there is no appropriate default constructor available. If I understand it correctly, "default constructor" refers to the constructor which lets you just write Array<int> a; instead of Array<int> a(...);, but I can't see where in the code such a situation occurs...

If I drop this regular dll project and create a new MFC extension dll project, it will involve too much work. I wonder if there is relatively easier way to convert an existing regular dll project to a MFC extension dll project? BTW, how can I tell a MFC extension dll project from a regular dll project?
