And in the /// part I also need to use the dot operator and the arrow operator to print on the screen info about the second and third Courses.

I am getting error at the assertion points when i call to the class as follows:
"A nested class has free access to all the static members of the enclosing class. All the instance members can be accessed through an object of the enclosing class type, or a pointer or reference to an object."
How can the members be accessed through an object of the enclosing class type? I understand the pointer and reference part because for them you dont need the full definition, but for creating a object you do?
Also it has free access to all static members because the nested class is part of the enclosed class and with static it exists in everything inside the enclosing class? Right or am I missing something?
I am getting the error on the implementation of my class name. The error is coming from my parkingControl.cpp 'ParkingControl parkingControlMenu;'. I have used this implementation fine before, but once I added a new main it stopped working. Below is my code.
I'm trying to learn recursion, and I'm using a simple array to experiment with it, but I have a couple of annoying errors that I don't understand why they're there. Here's the code:
Code: #include <cstdlib> #include <iostream> using namespace std; int largest(const int arr[], int lowerIndex, int upperIndex) { int max;
[code]....
Now try to print the array backwards:
//Use a recursive algorithm to find the largest element in arr: int largest(arr[], lowerIndex, upperIndex);//error: expected an expression return 0; }
The program should ask the user how many students were surveyed and dynamically allocate an array of that size. The program should then allow the user to enter the number of movies each student has seen.
#include <iostream> #include <string> using namespace std;
[Code].....
The problem I'm having is that where I declare movies = [numStudents]; the semicolon after the numStudents array is giving me this error - "error: expected a '{' introducing a lambda body".
I have been looking and i'm stuck on this. I wrote this program to find quarks and their charge and mass but i need it to give me 5 different ones. so i made an array but when i run it it gives me this
"Unhandled exception at 0x001631c6 in DiasQuarkP1V0.exe: 0xC0000005: Access violation reading location 0xd5bf0c38." and it shows the xstring library.
this is my main, is their anything wrong with my code?
#include "StdAfx.h" #include <stdio.h> #include <string> using namespace std; int main() { Quark solution[5]={};
what I want to say is, there can be several conditions for adding a signed int to an unsigned long:
1: if the ival is positive, then adding a positive to a positive, both value should be converted to unsigned long, which is reasonable, even when the sum is larger than the max limit of unsigned long, because user himself should be ware of that the sum value may be too large and will be modulo into the range of unsigned long.
2: if the ival is negative, but the sum is positive, then both sum and ulval can fit in unsigned long, so we should convert them into unsigned long
3: if the ival is negative, and the sum is also negative, that means the ulval's real value can actually fit in int range, so the compiler should convert it to int, so as to preserve the value. but compiler didn;t do this to comply it's "preserving value" rule.
i am doing some practice problems and i can't seem to figure out how to do this. basically we have a students number of test scores, then the name followed by the scores they have in a text file. Then we have to make a class with a constructor, copy constructor, destructor, and overload the = operator and the input and output operator. Are we suppose to call the text file in the input overload operator?
Here is what i have so far.
This is my header file.
#ifndef STUDENTTESTSCORES_H #define STUDENTTESTSCORES_H #include <string> #include <iostream> using namespace std; class StudentTestScores{ private: string studentName;
[Code]...
i am 100% sure the overloading the input is wrong
here is the implementation of the constructor copy constructor and desctructor
#include <iostream> #include "StudentTestScores.h" using namespace std; StudentTestScores::StudentTestScores(string name = "", int numScores = 0) { studentName = name; numTestScores = numScores; if (numScores <= 0) testScores = NULL; else
[Code]...

The program is suppose to use all the information and read from the notepad and output the exact things as the notepad file
The compiler keeps on telling me that invalid conversion from wxBitmap* to wxString on the line with the AddTool function, whiles I do not even try to do such an ambiguous typecast.

I am wondering why return type for an assignment operator cant be a void or int? Cant I write assignment operator for student class like this as we do nothing with returned value?
Student { char name[20]; int marks; public: student(char*name,int marks)
This is the main header with three classes, in summary ADNodeInstance is a data holder, ADNode is encapsulating a pointer to ADNodeInstance, and ADGraphBuilder is a main class which holds all the ADNodeInstances and manages them.:
From this all I could infer is that in the funcreateGradientMessage on the switch for TANH the segfault occurs for the expression: directGradient * child * (1 - child). From the output I can see that this is what happens in order:
Unary negation on node 5 resulting in 15Addition of node 16 and 15 (e.g. the brackets) resulting in 17trying to multiply 14 and 5 - SEGFAULT something wrong with 5
So my question is what exactly is happening? I tried to understand but can't.
