Jumlah barang banyak sintak C++

buat program untuk menghitung jumlah barang dengan inputan:

1. harga barang

2. jumlah barang

proses :

diskon = 10% dari total pembayaran

output:

total bayar = total pembayaran-diskon

#include<conio.h>

#include<iostream.h>

void main()

{

int a,b;

float c,d;

cout<<"masukkan harga barang = ";cin>>a;

cout<<"masukkan jumlah barang = ";cin>>b;

c=(a*b)*0,1;

d=(a*b)- c;

cout<<"maka totalnya ="<<d<<endl;

getch();

}

============================================================

#include<conio.h>

#include<iostream.h>

struct hitung{

int a,b;

float c,d;

    };

void main()

{

hitung harga;
