The Official Programming Thread

[Hassan]

so there are alot of software engineers or students who are enrolled in this field who perform programming on daily basis. Nowadays, programming is related to almost all the fields so people other than BSSE students also have to study programming. I am studying electrical engineering and they want me to study programming. I already know the basics, now i will be studying it in detail so if i or anyone else will be needing help regarding programming they may use this thread. However i will be learning and discussing programming with you guys. Looking forward to some cooperative guys.

If anyone needs help regarding any concept, i can help out

 

[StrikerX]

Damn... totally forgot about making this sort of thread...
[MENTION=4177]NaNoW[/MENTION] forgive me sensei Anyways, I'll write up something tonight or tomorrow. Also, should the thread stay here or better would be Software/Game Development and Programming ?



@others I'll make a draft for the first post and you guys can pitch in on what more to add and remove.

 

[Salvation]

let this thread stay here in my opinion since it will be used for learning purposes only, and not to forget that Education section is visited more often than the Software development section. Let that one serve its purpose for professional development purpose only i guess?

You have my permission :batman:

 

[Shary Bhallu TC]

Am also studying C Language and CAO in Electrical Engg. It's a good idea to make this thread, and will help many people including me (I hope).

 

[Gizmo]

Cool. I'm learning programming now too so I guess this is the right time for such a thread.

Yeah sure, that section is in the bottom so most people miss it as well ...

I think in any programming website..Codecademy.com should be mentioned ..its a pretty great site..

do you know Ruby? Im currently learning it from codeacademy... if i'll run into any problem i'll be sure to ask here....

I wanted a thread like this for a long time... and i'll say put it in the software development section as many people who know programming or are making games/softwares should remember that section very well... and personally i think i've seen many people there who know a lot and i don't see them in this section... just my opinion..
I already had a thread there where i asked about C# queries and i remember many people were helping me there so that'd be a good place...

If anybody needs Raspberry pi (a modern sexy controller with hdmi output) then contact me. I bought it last year for my Final Year Project and programmed it in python. It still has the programming of my FYP that is Heads Up Display. Ill post a picture of the controller and video of my project.

Ok so here is some really stupid problem i am stuck at. If someone could help it would be really appreciated.
I am working on a test android app just for learning purposes. The first two activities work fine, the translation animations work fine, opacity animations work fine, database works fine. But when I jump to the third activity, it pops up and is blank.
here is the XML code for UI

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

            android:layout_height="wrap_content"
            />
        
    </LinearLayout>

I am using Layouts within Layout. Overlapping Layout would be appropriate? Anyway the purpose is to slide the above layout so that the layout underneath appears.

Here is the code in my java class.

public class UpdateInventory extends Activity {

	Button insertShirt, insertTrouser,insertSuit, insertTie,back;
	EditText shirtColor,shirtTexture,TextureColor;
	Spinner color,texture,textureColor;
	LinearLayout optionToInsert,InsertShirt,InsertTrouser,InsertSuit,InsertTie,layout_base;
	
	private String[] shirtColors={"Beige","Tan","Khaki","Gray","Charcoal","Navy Blue","Medium Blue","Azure","Cyan","Forest Green","Olive","Light Green",
			"Lime","Coral","Pink","Light Purple","Purple","Indigo","Maroon","Crimson","Red","White","Brown","Black"};
	
	protected void OnCreate(Bundle savedInstanceState){
		super.onCreate(savedInstanceState);
		setContentView(R.layout.update_inventory);
		
		insertShirt=(Button) findViewById(R.id.btnInsertShirt);
		insertTrouser=(Button) findViewById(R.id.btnInsertTrousers);
		insertSuit=(Button) findViewById(R.id.btnInsertSuit);
		insertTie=(Button) findViewById(R.id.btnInsertTie);
		back=(Button) findViewById(R.id.btnBack3);
		
		color=(Spinner) findViewById(R.id.spinner_color);
		texture=(Spinner) findViewById(R.id.spinner_texture);
		textureColor=(Spinner) findViewById(R.id.spinner_texture_color);
		
		shirtColor=(EditText) findViewById(R.id.InsertShirtColor);
		shirtTexture=(EditText) findViewById(R.id.InsertShirtTexture);
		TextureColor=(EditText) findViewById(R.id.InsertTextureColor);
		
		optionToInsert=(LinearLayout) findViewById(R.id.layout_optionToInsert);
		InsertShirt=(LinearLayout) findViewById(R.id.layout_InsertShirt);
		InsertTrouser=(LinearLayout) findViewById(R.id.layout_InsertTrouser);
		InsertSuit=(LinearLayout) findViewById(R.id.layout_InsertSuit);
		InsertTie=(LinearLayout) findViewById(R.id.layout_InsertTie);
		layout_base=(LinearLayout) findViewById(R.id.layout_base);
		layout_base.setBackgroundColor(Color.RED);
		
		insertShirt.setOnClickListener(new View.OnClickListener() {
			
			@Override
			public void onClick(View v) {
				// TODO Auto-generated method stub
				TranslateAnimation animate= new TranslateAnimation(0,optionToInsert.getWidth(),0,0);
				animate.setDuration(500);
				//animate.setFillAfter(true);
				optionToInsert.startAnimation(animate);
				optionToInsert.setVisibility(View.GONE);
				fadein(InsertShirt);
				InsertShirt.setVisibility(View.VISIBLE);
			}
		});
	}
	
	public void fadein(View v)
	{
		Animation animation = AnimationUtils.loadAnimation(getApplicationContext(), R.anim.fadein);
		v.startAnimation(animation);
	}
}

here is the android Manifest Code, which of course works fine for previous two activities and this one loads fine as well

<manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="com.example.suitup"
    android:versionCode="1"
    android:versionName="1.0" >


    <uses-sdk
        android:minSdkVersion="14"
        android:targetSdkVersion="19" />


    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

        <activity
            android:name="com.example.suitup.MainMenu"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MainMenu" />


                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
        </activity>
        
        <activity
            android:name="com.example.suitup.UpdateInventory"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.UpdateInventory" />


                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
        </activity>
        
    </application>


</manifest>

I don't understand where the problem is? I have spent almost two hours but I cannot understand why the contents in the third activity won't appear?
It would be great if someone would help!

 

[Gizmo]

I have a C++ problem. I'm learning about pointers atm and I did this:

int Table(int a, int b){

int **p_p_table;

 p_p_table = new int*[a];

 for(int i=0; i<a; i++){

    p_p_table[a] = new int[b];


 }

 for(int i=0; i<a; i++){

    for(int j=0; j<b; j++){


        p_p_table[i][j] = i*j;
    }
    }

    for(int i=0; i<1; i++){

        for(int j=0; j<b; j++){

            cout << p_p_table[i][j] << "  ";
        }
        cout << " " << endl;
    }




}

int main ()
{
 int height;
 int width;

 cout << "Enter the Dimensions of the table: ";
 cin >> height;
 cin >> width;

  Table(height,width);


}

Basically, It's suppossed to be a function that let's the user create a multiplication table of their desired dimensions but whenever I run it and entert he dimension the program crashes because I'm not allocatting the memory correctly, How exactly do I do that?
