["Objects that are instances of an inner class exist within an instance of the outer class"](http://docs.oracle.com/javase/tutorial/java/javaOO/nested.html) Even though I attempt to create an independent instantiation of the inner class, the outer class is always there because of the statement above. ##Is that ture? If true, then that would also mean … |

Your program is nt behaving as wat u expect where sometimes it output the correct and at times incorrect result. During debugging,u manage to locate the problem to the following statement. A/b == c Where a,b,c are using the ieee 754 floating point representation and where the value c is … |

I'm trying to generate Unique ID's for a buffer unless they contain the same content. Inother words if the buffer has the same content as another, the ID should be the same; otherwise different. I've found someone using this algorithm for the same kind of buffer: DWORD CalcChecksum(DWORD *pData, int … |

Hello, I was curious to how I would go about modifying an existing text file (to all upper case) by the use of mapped memory. I think I have done the mapping correct, however I am stuck on how to modify the file. Help would be much appreciated, thanks! #include … |

Hi all! This is a simple piece of code that I wrote about a year ago, in response to a question on Daniweb. I decided to infuse it with some C++11 magic, which led to a pretty sweet code snippet, full of neat little techniques you might want to use, … |

I've been given a homework assignment in which I have to create a linked list, then store 25 random integers within it, after I've stored the values I have to find the sum of these 25 numbers, and then the floating point average of them. So for the most part … |

Am I freeing and declaring this 2d array correctly? int **ratings; ratings = (int**)malloc(sizeof(int *) * (numCouples*2)); for(i=0; i<numCouples*2*numCouples;i++) ratings[i] = (int*)malloc(sizeof(int) * numCouples); //Data is read into each array position for(i=0; i<numCouples*2;i++) for(j=0;j<numCouples;j++){ fscanf(ifp, "%d", &ratings[i][j]); //printf("%d",ratings[i][j]); } for(i=0;i<(numCouples*2);i++) free(ratings[i]); free(ratings); Thanks Drew |

This is a school assignment. I have to write a function in my program that opens a file stream and returns a heaped value to the main function. I believe the file opening function works but after it passes the ifstream pointer to the main function, I'm having trouble dereferencing … |

hi there!here's the problem in a nutshell: there are 2 files.the program creates 2 processes: the parent process outputs text lines from the 1st file and for each one of these lines the child process outputs relative info from the 2nd file. e.g. <1st line from file1> <relative info from … |

Hi everyone, At the moment I'm trying to create a class that contains a DOMNode* pointer, something like this class MyDOMNode { public: MyDOMNode (DOMNode* node) : mDomNode (node) { } bool operator== (const MyDOMNode& rhs) { if (mDomNode == rhs.mDomNode) return true; return false; } bool operator!= (const MyDOMNode& … |

First things first, I'm relatively new to C++. I'm just finishing up my first semester of computer science and I'm getting the error "Segmentation Fault (core dumped)" while opening a file in my final. I believe the error has to do with pointers and occurs somewhere in the while(!file.eof()) { … |

This is a minor issue that I'm having in a larger program. The program is for factoring a second degree polynomial. The function below is supposed to find the factors, which is does, but let's say a=6, b=1, c=-12 so a*c=-72 and I want the two numbers that will add … |

I'm at an absolute complete loss with this. I'm a using a pointer-pointer to "remember" the last node of a linked list so a function in the loop can add another node and then return the address of that new node so it's known for the next loop. Sounds easy, … |
