Urgent with the C++ assignment... pls help

tzeteng — Thu, 12 Oct 2006 22:10:41 +0800

Assigned to read each line of the data files (vehicles.dat) that contains sth like this...

AE45005 car
AS88925 lorry
AS15511 van
ASASAS lorry
.....etc

I have to file in them then sort the plate numbers into separate files according to vehicle type<--that's for file out display.. like "car.dat"... in C++ programme my display will have to display the number of each type of vehicles. I've done half a little bit which I doubted correct or not..

#include <conio.h>
#include <stdlib.h>
#include <fstream.h>
#include <string.h>
#include <stdio.h>

void main()

{

ifstream file_in("vehicles.dat");

if (file_in.fail())
{
cerr<<"File not found in disk.";
}

else
{
ofstream file_out1("car.dat"),file_out2("van.dat");
ofstream file_out3("lorry.dat"), file_out4("motorcycle.dat");
char data1[1000], data2[1000], data3[1000], data4[1000];

file_out1<<endl<<"\tType of Vehicles - CAR "<<endl;
file_out2<<endl<<"\tType of Vehicles - MOTORCYCLE "<<endl;
file_out3<<endl<<"\tType of Vehicles - LORRY "<<endl;
file_out4<<endl<<"\tType of Vehicles - VAN "<<endl;

char type = "apple";
for (int i=1; !file_in.eof(); i++)
{
file_in.getline(data1,1000);
file_out1<<endl<<"\t"<<i<<"\t"<<data1;
file_in.getline(data2,1000);
file_out2<<endl<<"\t"<<i<<"\t"<<data2;
file_in.getline(data3,1000);
file_out3<<endl<<"\t"<<i<<"\t"<<data3;
file_in.getline(data4,1000);
file_out4<<endl<<"\t"<<i<<"\t"<<data4;
}
}

getch();

}

Please help...

Please check my simple code..

#include <iostream.h>
#include <math.h>
#include <conio.h>

void main()

{
int speed;
float height;
char weather;

cout<<"Please enter the speed of wind" <<endl;
cin>>speed;
cout<<"Please enter the height of waves" <<endl;
cin>>height;
cout<<"Please enter the weather condition, T for thunder, R for rain, O for others" <<endl;
cin>>weather;

if (speed >= 45)||(height >= 3)||(weather=='T')
cout<< endl << "The condition is dangerous.";

else if (30 < speed <= 45)||(1.5 < height <=3)||(weather='R')
cout<< endl <<"The condition is cautious.";

else if (speed <=30)||(height<=1.5)||(weather=='O')
cout<< endl <<"The condition is safe.";

else
cout<<"Invalid";

getch();

}

I don't understand why I get Expression Syntax and Ambigous...error...
it indicates there's an error in the "if" parts

[WTA] Statics Question.... Please help

tzeteng — Fri, 04 Aug 2006 21:41:29 +0800

Can anyone try to solve this?

I got stuck here

3 T cos @ = 400, T = tension of each spring, @ = angle of spring with vertical axis
L sin @ = 0.5
L cos @ = h
tan @ = 0.5/h

with L = length of spring

T = 1000 times x where x is the stretch length

3000x cos @ = 400
x = L - 0.5
3000 (L-0.5) cos @ = 400
3000 (h) - 1500 cos @ = 400
3000 (h) = 400 + 1500 cos @
h = (400 + 1500 cos @) / 3000

and the I don't know how...

Furthermore I just directly used 1000 N/m stiffness given, maybe I should increase the value of stiffness since they are like in parallel arrangement...

Can I use a paid domain name with free hosting? Are the compatible together?

[WTA] Domain Name

tzeteng — Mon, 22 May 2006 23:31:10 +0800

Sorry but i don't know where to post... my question is about paid domain name registration... I saw a lot registration provided by many company.. Is it necessary to get new paid domain from a trusted company? Is it possible that I will lose my domain if that company is close?

For example I saw this

https://www.godaddy.com/gdshop/registrar/co...5Fhdr=&display=

How much usually it costs? about RM30sth annually?

I would also like to know the annual fee for webhosting....

What about lowyat.net?

For IPTA applicants who know this...

tzeteng — Sun, 23 Apr 2006 20:53:21 +0800

I'm currently waiting for my IPTA result which they say probably will be announced by the end of June.... But I would like to ask all the ex-IPTA applicants here if they got their first choice or not? I'm not sure how do the selections work... is it very hard to get the "First Choice" ?

Life in Local Public Universities of Malaysia

For those who have/had been experiencing the life in local University in Malaysia, mind to share the experiences with us? Maybe about some significant incidents.... or lecturers, etc..

I would also like to know... the first year we get admitted into the U, must we stay in the hostel there? And if we're going to stay there... is there internet connection available in every room? Can we buy desktop computer or laptop and bring there?
