TS, panu ilabas yung sum ng first 250 prime numbers?
Like this.

Netbeans naman gamit namin..Hehe may shortcut kasi sa gui development..
@sa taas
heto lang po logic jan:
int sum=0,x=0,y=1;
for(int a=0;a<250;a++)
{
sum=(x++)+(y++);
cout<<sum<<endl;
x=y;
y=sum;
}


di ko magets..
pakiexplain po..

panu naman po 'pag gusto ko hanapin yung may 15 digits na numbers.
ex. hanapin ko yung may 15 digit na fibonacci number..
panu source code nun?

pa-subscribe din

sir pwede pa help sa project ko! Eto po! Paano po hindi mauulit yung mga word?

Nahirapan ako dito sa java. Sa gui,lalo na wala pang pc..Wew

wow.. thanks sir. buti nakita ko tong thread na to. gusto ko gumawa o mag edit ng  mga java file

ididisplay nya po lahat ng fibonacci series of numbers below 250.. Kung 15 numbers lang po ganito po siya:
int x=0,y=1,sum;

for(int z=0;z<15;z++)
{
cout<<sum=(x++)+(y++)<<"\t";
x=y;
y=sum;
}


thanks dito i got it !,
 well done tut.

Sana makarating sa mga functions  ang topic...

Sir saan pwede makahanap ng magagandang look and feel. Thanks.

sir pwedi po ito sa win7 32bit gusto ko rin matuto ng programing kaso wala po akong idea.

Creating and using an Array

Example code to create an array of integer named nums with ten elements.
int[] nums = new int[10];or
int nums[] = new int[10];
Example code of intializing every element of nums array by 2:
nums[0] = 2;
nums[1] = 2;
nums[2] = 2;
nums[3] = 2;
nums[4] = 2;
nums[5] = 2;
nums[6] = 2;
nums[7] = 2;
nums[8] = 2;
nums[9] = 2;
Note that to initialize an array element you need to first type the array name which in this case nums and then followed by an open bracket. Then followed by a number from 0 up to array length minus 1, in this case the length of the array is 10 minus 1 is equal to 9. And then followed by a closing bracket, an equal sign and a value that you want put to the current array element.

If you know a looping statement like for loop you can also use that to initialize all elements of an array. For example:
for (int i=0; i<nums.length; i++) {
    nums[i] = 2;
}
Its worth noting that when using length attribute of an array, like in nums.length, it will return the exact length of array which in this case is 10.

Lastly to access an array elements value just do something like the code below:
nums[0];
nums[1];
nums[2];
nums[3];
nums[4];
nums[5];
nums[6];
nums[7];
nums[8];
nums[9];
but note that the code above will not print anything on the screen(console/command prompt). So insteand of doing that, just put that code inside System.out.println() just like this.
System.out.println(nums[0]);
System.out.println(nums[1]);
System.out.println(nums[2]);
System.out.println(nums[3]);
System.out.println(nums[4]);
System.out.println(nums[5]);
System.out.println(nums[6]);
System.out.println(nums[7]);
System.out.println(nums[8]);
System.out.println(nums[9]);
But if you know looping statement like for loop you can use that to lessen the code above. For example:
for (int i=0; i<nums.length; i++) {
    System.out.println(nums[i]);
}
Note that the code above produces the same result of the previous code with less typing. Always remember to write your code as shorter as possible. This will not only reduce your typing of code but also will makes your debugging much more easy.

Bonus:
Example code of adding values of of all elements.
int sum = nums[0] + nums[1] + nums[2] + nums[3] + nums[4] + nums[5] + nums[6] + nums[7] + nums[8] + nums[9];
But if you know looping statement like for loop you can rewrite the previous code like the following code below.
int sum = 0;

for (int i=0; i<nums.length; i++) {
    sum = sum + nums[i];
}
That's it we're done. I hope that you learn something from this tutorial.
