#include <iostream.h>

int main ()
{
char customerName,code,A,B,C;
int childNum,adultNum;
double rate,discount,totalPrice,a,c;
const double PriceA=95.00;
const double PriceB=100.00;
const double PriceC=120.00;

if (code=='A'||code=='a')
{

}

else if (code=='B'||code=='b')
{

{

rate=PriceC;
}
else
{
cout<<"Please Enter A Valid Code"<<endl;
}

if (adultNum==5)
{
discount=0.1;
}

else if (adultNum && childNum>5)
{
discount=0.25;
}

else if (adultNum && childNum>=15)
{
discount=0.3;
}

totalPrice=((a+c)-discount)+rate;

this is the code i got so far but it doesnt work

How does it fail?

Code tags would make the code more readable here.

int a, b, c;
...
a && b < c

That is a fail. It looks at 'a' first. If 'a' converts to false, then the result is false. Only if 'a' converts to true, the rest is evaluated, and the rest is 'b<c'. That is a boolean too. You probably did mean:
(a+b) < c

I don't understand discount "a". It seems to apply to only one very specific case.

Your equation for totalPrice is way of from how percentages operate.

help me..still cant get it right..:(

[junkz]

you must create new variable
ex.
int ab;

and than give value ab
ab=adultNum +childNum;


and than, change parameter
if else(ab>=5)
{
.... .....
}

my problem now,it cannot run,when i try to run,it only can run to enter the name,then the rest are not...guysss,,help me..this is my first time to study this kind of subject,c++.

[keskiverto]

char customerName;
cout<<"Enter Your Name:"<<endl;
cin>>customerName;

Line 3 extracts only one non-whitespace character from stream -- the first letter that you write.
Even if you would have std::string customerName, you would still get only the first word. Study std::getline.

does my code is wrong?anyone?please correct it for me..realy cant understand about this

[keskiverto]

Yes, your code is wrong. I did point to one error in my previous post.

If you understand nothing and we correct your code, then you still understand nothing. That is not the purpose of your study, and it is complete waste of our time.

i think the souce code like this,,

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

int main ()
{
const int max=100;
char customerName[max],code;
int childNum,adultNum,ac;
double rate,discount,totalPrice,a,c;
const double PriceA=95.00;
const double PriceB=100.00;
const double PriceC=120.00;

cout<<"Enter Your Name:"<<endl;
cin.getline(customerName,max);
cout<<"Enter The Number of Children:"<<endl;
cin>>childNum;
cout<<"Enter The Number of Adult:"<<endl;
cin>>adultNum;
cout<<"*Package Destination Package Code*"<<endl;
cout<<"*Pulau Redang:A*"<<endl;
cout<<"*Pulau Perhentian:B*"<<endl;
cout<<"*Pulau Kapas:C*"<<endl;
cout<<"Choose Your Destination By Enter The Code:"<<endl;
cin>>code;

ac=childNum+adultNum;

if (code=='A'||code=='a')
{
a=adultNum*30.00;
c=childNum*15.00;
rate=PriceA;
}

else if (code=='B'||code=='b')
{
a=adultNum*30.00;
c=childNum*20.00;
rate=PriceB;
}

else if (code=='C'||code=='c')
{
a=adultNum*20.00;
c=childNum*10.00;
rate=PriceC;
}
else
{
cout<<"Please Enter A Valid Code"<<endl;
}

double tP=a+c+rate;

if (adultNum==5)
{
discount=0.1;
totalPrice=tP*discount;
}

else if (ac>5)
{
discount=0.25;
totalPrice=tP*discount;
}

else if (ac>=15)
{
discount=0.3;
totalPrice=tP*discount;
}
else
{
totalPrice=tP;
}



cout<<"\n====================================================="<<endl;
cout<<"\nCustomer's Name:"<<customerName<<endl;
cout<<"\nNumber of Children:"<<childNum<<endl;
cout<<"\nNumber of Adult:"<<adultNum<<endl;
cout<<"\nTransportation:"<<code<<endl;
