patambay para sa mga future assingment namin sa java

flowchart pa lang kasi kami ngayun eh
 
Sir Raymundpogi may project po kasi kami , nakakahiya mang magpatulong pero alam kong sisiw lan to para sa mga katulad nyo (EE student from FEU , di ko naman major yn at Comp. Engr. lan ang may kelangan nyan hanggang higher yr) :slap:

Bale po addition of binary ang project namin para sa microsoft visual studio 2010 (.c)
Mag iinput ng 5 binary numbers ang prof. namin kahit anu (binary 0,1) , halimbawa 0001110,0001110,1100,00011110,0101 tapos ang magiging output yung sagot nyan ng addition of binary , ganun lan po , sana matulungan nyo ako :help: :help: :help:

Kakapalan ko na po ang mukha ko samahan nyo na rin po ng FLOWCHART after nyo magawa after kasi mapa run , ieexplain sya through FLOWCHART ,..

Salamat po talaga kung sino makatulong :clap:

hindi pa po namin pinag aralan yang Micosoft Visual Studio sir. Hehe, at wala pa po akong background diyan kasi sa Web Dev po ako nakatutok ngayon. I think meron pong thread dito sa Programming section ang makakatulong sayo at kung wala man, pwede ka po magcreate para sa "agarang aksyon".. :thumbsup:
 
Sir, Sakin naman po ang problema lang sa java calculator ko is halimbawa nag add ako ng 2 numbers like 1+1 ang answer na binibigay sakin is "2.0" imbis na "2" lng

Cast your double value to int when printing. Ie: (int)total

A program to demonstrate the search, suppose you have a text file name: "Data.txt" that contains the ff fields : Student # , FName , LName, MI, Course & Year . Make a Program that recieve in input ( student # or Last name) from the user, search these data from your file then display the matching record on screen as well as write this into another file: "Data_Findlist.txt"



pa Help po
 
Lagay mo sa list ang data mo paps saka search mo na lang ng sequential. .equals() gamitin mo pag string.
 
GUYS paturo naman dito kailangan na namin ksi gumawa nito until 12midnight pasahan c++ or java thanks :)

EXP5

Quick sort. It starts with choosing a partitioning element called the pivot. The elements will be divided according to the pivot, one part contains elements that are less than or equal to the pivot, the other part contains elements that are greater than the pivot. New pivots are chosen until arrays contain only 1 or 2 elements when necessary comparisons are performed.

Create a program that implements quick sort. Any programming language can be used. Create a function/method that uses the concept of quick sort. Pivot shall always be the first element in the array. Show the number of comparisons and the value of the set of elements per pass. Maximum number of elements is 15.

http://*** BANNED LINK - DO NOT POST ***/fWnAj9PF

mga sir pa help naman sa program ko, file handling , yung mag add ako ng info if may duplicated na sya sa student number or sn palang dapat error na sya , di ko talaga mahanapan ng way panu lagyan ng command na kung may duplicate ehh may sabi na sya file already exist :noidea:
 
nice thread sir..dito ako mag-aaral kapag may hindi aq alam sa c++ namin..:excited::excited::excited:
