If you want Java, you could do it all pretty easily with Java 7 (JavaFX for GUI and Media/MediaPlayer). For outside libraries with Java 6, JLayer and mp3transform are pretty fancy.Hi Programming-GAF,
I want to build a better programming portfolio than just school projects that I have from college and the first thing that came to my mind was MP3 player. I don't know where to begin and what language would be best for a MP3 player. Preferably, I would want to work with Java. I also don't have any experience with GUI other than working with front-end HTML/CSS so it will be entirely new to me. Can someone point in the right direction to get started on such a project?
Thanks
Non-member friend functions are coupled to the class like members are and should probably be in the implementation file with all the members.
PYTHON/PYGAME RELATED
Pretty picture of my game thus far:
- (void)orientationDidChanged: (NSNotification *)notification {
UIDeviceOrientation devOrientation = [UIDevice currentDevice].orientation;
if (UIDeviceOrientationIsLandscape(devOrientation)) {
UIStoryboard *main = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
HorizontalController *horizontal = [main instantiateViewControllerWithIdentifier:@"horizontal"];
[B][self presentViewController:horizontal animated:YES completion:nil];[/B]
} else if (UIDeviceOrientationIsPortrait(devOrientation)) {
[self dismissViewControllerAnimated:YES completion:nil];
}
}Is JavaFX a library or built in Java SDK?
#include <iostream>
#include <math.h>
#include <iomanip>
using namespace std;
int main()
{
const int MAX_ITERATION = 21;
double sum, totalSum;
double x = 3.0;
double y = 0.0;
for (int i = 0; i < MAX_ITERATION; i++, x+=2, y+=1)
{
if (i % 2 == 0)
{
sum -= (1.0/(x * pow(3,y)));
}
else
{
sum += (1.0/(x * pow(3,y)));
}
}
totalSum = sqrt(12) * (1 - sum);
cout << totalSum << endl;

SSLVerifySignedServerKeyExchange(SSLContext *ctx, bool isRsa, SSLBuffer signedParams,
uint8_t *signature, UInt16 signatureLen)

goto fail;

}You have an appropriate tag. Also, it's impressive what a difference a nice background makes.
You can get everything set up pretty easily, including the GUI maker, by getting e(fx)clipse and making a JavaFX Project.
I know it's not preferred style, but this is why I always use braces.
Are you not initializing sum?I'm in need of some help. I'm trying to calculate Pi using the Liebniz Series.
Here's what I have so far:
Code:#include <iostream> #include <math.h> #include <iomanip> using namespace std; int main() { const int MAX_ITERATION = 21; double sum, totalSum; double x = 3.0; double y = 0.0; for (int i = 0; i < MAX_ITERATION; i++, x+=2, y+=1) { if (i % 2 == 0) { sum -= (1.0/(x * pow(3,y))); } else { sum += (1.0/(x * pow(3,y))); } } totalSum = sqrt(12) * (1 - sum); cout << totalSum << endl; }
I'm using a for loop to do it, and the nested if loop is supposed to alternate between adding and subtracting. I've been trying to get this to work for a while now. I get 2.49657 which obviously isn't right. Could someone give me a nudge in the right direction? Just a hint please, I'd like to tackle this primarily on my own merits... but I've hit a road block atm.
If the first two if statements fall through, the 3rd goto will be executed.
My experience has been that using single-line if/while/for expressions leads to bugs. You might be able to handle it, but in several large-scale projects with multiple developers I've seen a lot of bad errors as a result of doing that, and no corresponding errors from an excess of braces and whitespace. You don't even get RSI from it any more, as your IDE will put them in for you.
Like I said, we've got different stylistic preferences here, I suspect, and there's probably not a definitive 'right' way to do most of these things.
Personally, I like Bumblebee as an example. Its consequences are more immediately understandable. It would have been caught by end to end acceptance tests on some of the projects I worked on (though admittedly, not all).
I'm kinda surprised g++ says nothing even with -Wall -Wextra.
#for Fedora / Red Hat
sudo yum install valgrind
#or for Ubuntu / Debian
sudo apt-get install valgrind
valgrind ./calcpi
#or whatever you named your program
#instead of calcpiI'll probably butcher the argument, because I don't agree with it, but some people like it because:
Nice one JetBrains, gotta love them turning Apples mistake into a marketing opportunity
