C++ :: Coding And Debug Time Per LOC

Mar 23, 2013

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:

Code: #include <iostream>
#include <fstream>
#include <string>
#define SPACE_SEARCH 10
using namespace std;

[code].....

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?

Im having problems coding this
A = P(1 + r/n)nt

//Declared test cases
float principal = 200000.00, annualInt = 0.03;
float years = 10.0;

float calcInterest1(float principal, float years, float annualInt) {
float interest1;
float nt = annualInt*12;
float A = principal+annualInt;//Accrued Amount
interest1 = (A = (principal*(1+years/100))pow(nt));// A = P(1 + r/n)nt
return interest1;

C/C++ :: Falling Object Error When Coding

Mar 4, 2014

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.

Sample Output (This program has no input)

Seconds Distance
================
1 16.1000
2 64.4000
3 144.9000
4 257.6000
5 402.5000
6 579.6000
7 788.9000
8 1030.4000
9 1304.1000
10 1610
11 1948.1000
12 2318.4000

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);

[Code] ....

which gave me this error:

1>------ Build started: Project: Lab 6, Configuration: Debug Win32 ------
1> Source.cpp
1>c:usershanahdocumentsschoolprogamming ilab 6lab 6source.cpp(27): error C2065: 'fallingdistance' : undeclared identifier

C++ :: Coding A Loop Inside A Class To Use In Main

Feb 22, 2013

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');

C Sharp :: Coding For Quantities In Online Shopping Carts?

Jan 11, 2013

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?

C# :: Audio Visualization For RGB STRIP

Apr 7, 2015

I have a RGB STRIP connected to Arduino, when im communicating via Serial. All works great! So next i wanted to make some audio visualisation.. So i found some samples etc.. and then i created the Audio Visualisation via C# using BASS.NET, when R has been BASSes, G medium frequency and B high frequency. But isnt looking good, so i started thinking, what 3 variables in song has can use, but this is bad idea.. I got idea to change to random color when its get "beat" or BASS hit some value. I tryied 4 hours of doing it, searching, programming... But i cant do it...

So, my question is how to detect the beat or just anything event for Audio Visualisation. Best output form WASAPI. Only what i can do is get FFT and Audio Spectrum from WASAPI by BASS.NET, but thats all. My audio skills is so low for this.

C++ :: Giving Audio Input To A Program

Sep 27, 2013

I want to give audio-input to a FFT code (KissFFT) written in C, on a real-time basis. While I can give a simple test signal (like sine wave) by writing the sine function as input, I am not sure how I should convert an audio-signal (e.g.: song) into a form that can be taken as input by the KissFFT C code.

C++ :: Radio Station - Streaming Audio On The Web

Jan 22, 2013

work for a radio station as their webmaster, and we have been looking into online streaming options for the last few months for our website. Pretty much everyone charges a monthly fee for this type of service and I feel like it is something I am capable of doing myself.

At the station we have a computer dedicated to operating the music/talk. On this computer there is a program that ques all the music, ads, ect.. This would be my audio source: Either the program playing all the music, or the computer itself.

The problem I have been pondering all night is how would I access this input source? The only audio input I am familiar with accessing is .mp3 or .wav files. How can I code my program to access this audio the program is producing and stream it to people on the web?

C++ :: Audio Programming (wave Format)

May 31, 2012

I have problem with this code:

Code:
#include <string>
#include <fstream>
#include <iostream>
#include <cstdlib>
using namespace std;
// multiplier
const double MULTIPLIER = 0.0000001;

[Code] .....

It should cut wav files into smaller pieces using text file .lab (the values multiplied by * 0.0000001 gives time in second. For example, i have such file with recorded yes and no: [URL] ..... and such boundaries [URL] .... It all should be in the same folder, then, after puting "yesno.wav" into command line and press enter it should gives 2 files with yes and no words. But it doesnt - i obtained one file with silent and one short sound. The record is recorded by Audacity, default sample rate 44100, default sample format 16-bit.

C :: Can Play Audio Without Extra Window Showing?

Jul 7, 2013

I got this code from a wiki that taught me how to make C code that plays audio, and with a few changes I was able to get it to take a command-line argument as the music file name. Here it is

Code:
#include <stdio.h>
#include <stdlib.h>
#include <SDL/SDL.h>
#include <SDL/SDL_mixer.h>

int main(int argc, char *argv[])

[Code] ....

The only problem is, even though I guess it needs to create a window to work with SDL, is there any way you could hide it or something so the user can't see it? I don't really want to see it ( I'm planning on running it from Batch files or C applications as an easy way to play an audio file once ), because if I did, I might as well just use a default audio player instead.
