Loop tu run 4 kali.
1 + 4 sebab cin yang 1st tu luar loop. sebab tu nampak cam 5.
kalau aku, aku akan buat camni.

[code]#include <cstdlib>
#include <iostream>

using namespace std;

int main(int argc, char *argv[])
{

int j, score[5], max = 0;
cout << "enter 5 scores ...\n";

for (j = 0; j < 5; j++)
{
cout << "score number " << j + 1 << " : ";
cin >> score[j];

if (score[j] > max )
max = score[j];
}

cout << "\n\nThe highest score is : " << max << endl;

system("PAUSE");
return EXIT_SUCCESS;

}[/code]

defaultkan dulu max kepada 0.
lagi satu, kalau nak lagi cantik, j ngan array tu buat dynamic.
so suruh user yang masukkan berapa byk scores yg dia nak.
jadi takdela fix 5 je untuk array.

#include <iostream.h>
void main ()

{

int i, angka [6] = {1,2,3,4,5,6} ;

for ( i=0 ; i<6 ; i++ )

{ angka[i]=i+1 ;
cout << "masukkan integer : " <<angka[i]<<endl ;


}

}

macammane nk jadikan output coding ny dalam reversed order??
output yang ak dapat sebelum reversed order..

masukkan integer :1
masukkan integer :2
masukkan integer :3
masukkan integer :4
masukkan integer :5
masukkan integer :6

[ahaksz! 44]

reverse counter dari 5 ke 0..


[code]
for ( i=5 ; i != -1 ; i-- ){

cout<<"Reversed: "<<angka[i]<<endl;

}
[/code]

EDIT:

tapi yang pelik sikit dekat sini..

[font="Courier New"]int i, [b]angka [6] = {1,2,3,4,5,6}[/b] ;

[b]angka[i]=i+1[/b] ;[/font]

first tu dah initialize array [font="Courier New"][b]angka[/b][/font] tu apa element dalam dia..
then dalam loop tu buat yang sama..[s]array size pun rasa salah tu..
kalo ikot [font="Courier New"][b]angka [6][/b][/font], element dalam angka mesti ada 7 sebab index start dari 0 sampai 6..[/s]

sy da dpat coding da tok reversed order 2..wat sendiri td..:

#include <iostream.h>
void main ()
{
int i,angka [6] = {1,2,3,4,5,6} ;
for ( i=0 ; i<6 ; i++ )
{ angka[i]=i+1 ;
cout << "masukkan integer : " <<angka[i]<<endl ;
}
for ( i=0 ; i<6 ; i++ )
{ angka[i]=6-i ;
cout <<"susunannya adalah :" <<angka[i]<<endl ;
}
}

tp sy buat coding 2..betul mcm ape output dy dkehendaki..

[s]yap memang betul tapi cuba comment dulu line ni

[font="Courier New"][b]angka[i]=6-i ;

angka[i]=i+1 ;[/b][/font]

and then run..[/s]

woot.. maap.. salah paham dengan coding.. memang betul dah coding bro hamster91..cuma rasanya value yang di declare dekat array [b]angka [6] = {1,2,3,4,5,6}[/b] tak pakai pun..

Macam kata ahaksz28, nampaknya takde guna value assignment kat angka tu.

default:
cout<<"the code you have entered does not valid"<<endl;

cout<<"the net price is:RM"<<cash<<endl;
cout<<"the instalment price is:RM"<<instalment<<endl;
}

return 0;
}







ape yang salah pada coding sy ny??
sy nk run program xbole la...
mslh kat formula ke????

[ahaksz! 44]

err.. nape pakai char ek.. tak pakai String?

[hamster91 0]

haa???string??
erm..sy blaja c++ xgune string pn..char je..

formula untuk case 'I' tu betul ke??
sy wat mini projek untuk system pembelian kereta..

[ahaksz! 44]

hmmm.. kenapa tak declare variable [font="Courier New"][b]code[/b][/font] macam biasa je.. no need [font="Courier New"][b][50][/b][/font].. so just declare jadi [b][font="Courier New"]char code;[/font][/b]


[quote]switch ([b][font="Courier New"]code[/font][/b]){

case 'C':
cash=[b][font="Courier New"]normal_price-(0.3*normal_price);[/font][/b]
break;

case 'I':
month=year*per_year;
instalment=normal_price*month;
interest=instalment+30;
break;

[font="Courier New"][b]default:
cout<<"the code you have entered does not valid"<<endl;
}[/b][/font]

cout<<"the net price is:RM"<<cash<<endl;
cout<<"the instalment price is:RM"<<instalment<<endl;[/quote]

default tu patut sampai [b][font="Courier New"]cout<<"the code you have entered does not valid"<<endl;[/font][/b] je.. kalo tak output yang 2 lagi kat bawah tu takkan display unless user salah tekan huruf selain C or I.. one more thing kalo boleh tambah untuk lowercase c dengan i..mean even user tekan lowercase c still program tu accept input sebagai Cash..

contoh:
[quote]
case 'C':
[b][font="Courier New"]case 'c':[/font][/b]
cash=normal_price-(0.3*normal_price);
break;[/quote]


err..actually nanti memang akan calculate installment juga ke kalo dah pilih Cash?
if not better letak [b][font="Courier New"]cout[/font][/b] yang last tu dalam case memasing.. kalo tak even pilih Cash installment punya output still keluar..

contoh:
[quote]
case 'C':
[b][font="Courier New"]case 'c':[/font][/b]
cash=normal_price-(0.3*normal_price);
[b][font="Courier New"]cout<<"the net price is:RM"<<cash<<endl;[/font][/b]
break;[/quote]

and lastly kalo boleh make sure each variable yang di declare initialize kan value dia..
macam normal_price, salary, year, month tu equal to 0.. kalo tak macam sekarang ni bila last nanti dia akan keluar nombor pelik2 time result dia kalo condition salah..


p/s sorry kalo solution ni lari dari soalan or skop sistem yang nak dibuat..

boleh x sape2 tulung pelbagaikn lg fungsi progrm ny slaen dpd bole kire cara bayaran pmbelian kete je..
sebb lect kate kalo g byk fungsi g bgus.. ;D
soe lme x msk forum..bz ngn mcm2 mini projek..huhuhu
