Berikut adalah contoh program nested if sederhana

#include<conio.h>
#include<iostream>
#include<stdio.h>
main()
{
awal:
clrscr();

char kode,ukuran,*merk,input;
int harga,sub,jumbel;

cout<<"                 Penjualan Baju Di Toko Nested"<<endl;
cout<<"          +*+*+*+*+*+*+*+*+*+*+*+*+*+*+*+*+*+*+*+*+*+*+"<<endl;
cout<<endl;
cout<<"Pilih Kode Baju [1/2]     :";cin>>kode;
cout<<"Pilih Ukuran Baju [S/M/L] :";cin>>ukuran;

if(kode=='1')
    {merk="H&R";
   if(ukuran=='S')
   harga=45000;
else if(ukuran=='M')
    harga=46000;
else
    harga=47000;
   }
else
    {merk="Adidas";
   if(ukuran=='S')
   harga=50000;
else if(ukuran=='M')
        harga=51000;
else
        harga=52000;
      }
clrscr();                                                                      
cout<<"                 Penjualan Baju Di Toko Nested"<<endl;
cout<<"          +*+*+*+*+*+*+*+*+*+*+*+*+*+*+*+*+*+*+*+*+*+*+"<<endl;
cout<<endl;
cout<<"Daftar Penjualan Baju"<<endl;
cout<<endl;
cout<<"Merk Baju   :"<<merk<<endl;
cout<<"Ukuran Baju :"<<ukuran<<endl;
cout<<"Harga Baju  :"<<harga<<endl;



cout<<"Jumlah Beli  : ";cin>>jumbel;
cout<<endl;
sub= harga*jumbel;
cout<<"Jumlah Bayar ="<<sub<<endl;
cout<<endl;
cout<<"Mau Input Data Lagi?";cin>>input;
if(input=='y'||input=='Y')
goto awal;
else
goto akhir;

akhir:

}
