I just spent 3 hours writing and debugging 37 lines of code. Is this normal or am I "below average" in coding abilities. I come from a C background and decided to write C++ code that I finally got right as shown below for the specific example:
I think it was more the learning along the way that consumed atleast 75% of my time for this specific case. But then again, I read that programming always entails learning along the way and so its somehow no excuse for the long time taken in this specific case.
So as a matter of interest, what pace do all of you operate on, on average? i.e. LOC/day, Debugs per day or any other indicator of productivity?
Is there a way to put a mp3 file into a c program without having the windows media player pop up in the background each time you compile the program? I just wanted to input a few seconds of an audio file..
I'm interested in learning how to write the software for audio synthesizers. a friend of mine started on the hardware side for them and, as i have no experience with this type of code.
Write a program that computes how many feet an object falls in 1 second, 2 seconds, etc., up to 12 seconds.
1.Have a procedure called FallingDistance which has one input parameter, seconds, and one output parameter, distance. 2. Compute the distance in feet an object falls using this formula: d = ½ gt2 (where g = 32.2) 3. The main program should call FallingDistance within a loop which passes the values 1 through 12 as arguments. 4. Print a table with seconds and falling distance in feet.
In C++, the procedure is called a function. Instead of using an output parameter, your C++ function FallingDistance should return a result of type double. This is what I created:
#include <iostream> #include <cmath> #include <string> using namespace std; const double g =32.2; double fallingDistance(double);
I am writing a program where all work is done in the class methods. Main is used to call the methods. I need to know how to get a loop to work without any variables in main that can be used outside the methods. This is what I have in main:
#include <iostream> #include <string> using namespace std; #include "FerryBoat.h" int main() { //create a constructor for a ferry boat FerryBoat myBoat('B', 20, 'A');
I am trying to create an on-line product store. I'm having trouble with setting up the code to correctly acknowledge quantity desired per product item in the shopping cart at check-out. I want to be able to capture multiple impressions/hits/clicks per item and increase the # in the quantity box each time someone clicks on the same item. For example, if product A is clicked 3 times, then the quantity in the shopping cart should show "3". If it's clicked 5 times, it should show "5" and so on ... However, right now, it's showing the product multiple times in the shopping cart with a quantity of "1" for each time the item was clicked. How can I correct this?
iam writing the statements in to this log by using fprintf(). As the .exe where i have put this mechanism runs continuously,the size of log file is increasing gradually.
1)If there is any way to restrict the Log file size,if the file reaches the mentioned size,the file should be discarded and logging should be done in another file with the same name.
{OR}
2)Put a time interval,once after that interval is elapsed, a new log file should be created.
This is a round robin execution. with gantt chart. arrival time and burst time. I think there is an error in my formula to get the right answer,i cant resolve it but my program is running. What is the code or the right formula??
#include<stdio.h> int main(){ int i,j=0,n,time,remain,flag=0,ts; int sum_wait=0,sum_turnaround=0,at[10],bt[10],rt[10]; int ganttP[50],ganttStartTime[50]; printf("Enter no of Processes : "); scanf("%d",&n); remain=n;
I'm currently just trying C++ with SFML. So I've installe SFML 2.0 for Visual C++ 2010 Express 64 bit, and I get an error while trying to run the debug of my code.
I get this error when i try to run this code for an inventory in debug mode in VS. But for some reason it works just fine in release mode.
void Push_Back_Item(Item *item){ for(int y = 0; y < InvSizeY; y ++) for(int x = 0; x < InvSizeX; x ++){ auto Iter = ItemList.find(std::make_pair(x,y)); if(Iter != ItemList.end()){ item->SetDead(); // ERROR } } }
This isnt the full code though but it still gives me the same error.
The only thing "item->SetDead()" does is to set a bool to true.
This is the map i get the iterator from std::map<std::pair<int,int>,Item*> ItemList;
This have been bugging me for quite some time now.
i've got an assigment that requires me to overload some operators and add some objects together.
I will show the code and explain as good as I can.
void SArray::operator+= (const SArray &obj) { Sphere * tmp_arr; tmp_arr = new Sphere[obj.antalobjekt+this->antalobjekt]; //antalobjekt = //Gets amount of elements in the arrays.
[Code]......
m_arr is the inner array for storing elements, do ask if something is not clear enough. The copy constructor works, so i have not included it.
I get this error when I'm attempting to delete an array. I'm new to dynamic arrays, and from what I have learned, arrays must be deleted after use. I plan on using this in a function later on, so deleting the array is a must.
Here's the error message: Debug Error!
HEAP CORRUPTION DETECTED: after Normal block (#154) at 0x007E55A0. CRT detected that the application wrote to memory after the end of heap buffer.
Here's my code: int main() { //Declare variables char persist = ' '; int* primes = NULL; int size2 = 0;
You place a breakpoint at one of locations within the message loop. But I want the breakpoint to trigger when I click on the application window, for example. But I can't, it went so fast so long as I switch from VS to the application program, the breakpoint is hitted again, then the application is frozen again. I don't know how to setup a conditional breakpoint.
i changed my code from release to debug mode. when i try to debug it shows a dialog box that '... does not contain debug information press ok to continue"..
I have a MFC Com Dll that has a CDialog. In the OnCreate event I create an ActiveX control. The dll is hosted inside an executable of mine. In this scenario everything works fine!
The dll is also called from an external executable and then a Debug Assertion in OCCSITE.cpp occurs when I create the ActiveX control. I suspect that in the executable there is no AfxOleInit. I spend some time with this problem and tried to CoInitialize, OleInitialize, AfxOleInitModule and even AfxOleInit in the dll. But all that does not change a thing. If I understand the mechanics then this is an intended behaviour and should be done in the host exe.
In my executable m_bNeedTerm is 0 and in the external one (where the ActiveX does not work) it is -1. In AfxOleInit this is explained as a special flag to prevent the dll from doing an unnecessary OleInitialize. But as I said even if I call OleInitialize myself I get the Debug Assertion and the ActiveX is not visible.
Is there anything I can do to make the ActiveX control work in the external application? Obviously I cannot Change anything in the application...
