Switch and Case in c++ - a blog of a local hero wannabe

oh yea to create option on c++ we can use this function. swicth and case in c++ is just like case..of in pascal and php i think. here is the example :

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

void main()
{
int *a=new int;
int *b=new int;
int *c=new int;
int pilih;
int menu;
do{
    clrscr();

cout<<"menu pilihan"<<endl;
cout<<"1.keliling & luas segitiga siku-siku"<<endl;
cout<<"2.volume & luas bola"<<endl;
cout<<"3.keluar"<<endl;
cout<<"masukkan pilihannya:";
cin>>pilih;

switch (pilih) {
    case 1:cout<<"hitung segitiga"<<endl;
    cout<<"alas segitiga:";
    cin>>*a;
    cout<<"tinggi segitiga:";
    cin>>*b;

    *c=sqrt((*a**a)+(*b**b));
    cout<<"keliling segitiga:"<<*a+*b+*c<<endl;
    cout<<"Luas segitiga:"<<1.5**a**b;

break;
    case 2: cout<< "hitung bola"<<endl;
                    cout <<"Jari - Jari : ";
                    cin>>*a;
                    cout << "Volume : "<<((4/3)*3.14**a**a**a)<<endl;
                    cout << "Luas Selimut : "<<(4*3.14**a**a)<<endl;
                    break;
}
getch();
}
while(pilih!=3);
getch();
delete a,b,c;
}
