this ERD for Online Library management system . the diagram attached

account No. ....... Pin No........Name........Balance
ex: a0910........21996........james........210.000

1) write a program to store data instance for 50 customers , and sort in the order of account no and take a report of all customers.

2) To store a data in a file .

i admire Senior members and their comments & suggestions.

i am just trying to discuse with them .
i want answer for my problem

there is more :(

there are a mistakes i dont know how to solve it .. i am trying :(

#include<stdio.h>
#include<conio.h>
 
void main()
{
 float total,average, s;
 int i;
 int a;
 clrscr();
  printf("Enter the numbers : ");
 scanf("%d",&a);
 for ( i=0;i<a ; i++)
 {
  total=total+a;
  s=s+1;
  }
   average =total/s;
 printf("The sum of numbers are %f and the average is %f",total,average);
}

i need another solution for for looping

thaaaaaanx WaltP ;

i am still trying

#include<stdio.h>
#include<conio.h>
 
int main()
{
 float total,average;
 int s;
 float a;
 clrscr();
do
{
total=total+a;
  s=s+1;
}
 while((scanf("%f",&a)>0));
 average =total/s;
 printf("The sum of numbers are %f and the average is %f",total,average);
}

the problem that i need to use this program in another way
for example : for looping , do-while looping

hello every body

i have a problem with a c program .
the question that ( write a c program that reads a real numbers untill error then calculate the sum and the average of all numbers )

i have solve it with a while looping . and i need it with adiffrent looping .

#include<stdio.h>
 
void main()
{
 float total,average;
 int s;
 float a;
 
 while((scanf("%f",&a)>0))
 {
  total=total+a;
  s=s+1;
 }
 average =total/s;
 printf("The sum of numbers are %f and the average is %f",total,average);
}

How r u every body.
I have some qoustions:
1)What is the difference between an instance data field and a static data field??

2) Also I have assignment and i wont to add txt on text area and when add new one txt it must appear in next line of text area ???

hi every one
i want C program to store 10 characters in alphabetical order using merge sort and quick sort?

and another program to input 10 names ,maximom of 25 characters ,using merge sort and quick sort?

come-on ... why u r not want 2 be helpfull ..

i ask 4 help ..

We are not here to give you the solution. We are here to help you find the solution if you show initial effort. Where's the effort ? Tells us what have you searched on the net about threads in Linux/Windows. What you are only putting effort in is writing useless posts without following what others are tyring to tell you.

thats mean u want all things what i have found it in the net .
i saw many things . but it diffecult to found spisific information about the operating systems. so, could u advice me ??

waaaaaaw . i think we r here 2 help each other . if i know the solution . i'll not ask 4 help .

And is your report getting done?

what u mean ???

am waiting 4 help .. :(

So write it. It's your homework and this has nothing to do with Java.

i dont know.
where can i put it ??

write a report on threads in operating systems such as Linux and windows XP ?

see attached file

hi

i have question .

what data type of time ??

Hi ,
how are you?
please, could you help me to solve this question?
which is a part of the compitision's questions.
I am waiting for your respond!

in this code give me another solving it not work correctly

public void initializeColor() {
        // TODO Auto-generated method stub
        double a =Math.random()*10;
        if(a<7.0)
            color=normal;
        else
            color= abnormal;

    }

yeah you do.. not necesarilly ours though.
if I read over this code you've posted, it seems that in the comments you can write flawless (or almost flawless) english, while in your posts, you only reach to the level of my 2-year old cousin's english, and he has never even heard english, let alone tried to speak/write it.

this gives me the idea that you did not write this code, this was given to you as your assignment, or as aid by someone who did you one huge favour.

stop trying to cheat your way through, and put some effort in it yourself.

this shows you haven't even read your assignment, so, why should we?

upon my word I wrote this code and no one given to me as my assignment, or anything else >> please choose your word carefully>>
And I'm sorry to ask help from you>>

my friend could u help me by give me the code of print array at least!!!

hi my frinds ,,,

what happen..there is no one want to help .. i do not why ,, i need only this progam ,, i stay in daniweb mor than one week and no one want 2 help ,,i do not no why ,,

please our frinds ,,, do not forget me

i need the idea

hey ddanbe ;

my problem is i want to solve the program >>

hey my frinds ...

there are 227 views and no one want to help me >>

as we know if the person dose not know how to find what he or she want . he/she has to ask others >>>

and i come to to ask my frinds .. not to teach me hot to write .

the general idea is: you analyse your assignment, check what kind of data (variables, Objects, ...) you'll need, what kind of actions must be performed on them, ...

then, you start creating your Objects, after which you create the code that uses them, you compile and run it

h'm sure i'll do these steps >>>

but i need more explaination

i need only the idea to solve it >> and i will do it by myselfe >>>
