cout<<"Jumlah Bilangan 1 + Bilangan 2 = "<<sum;
return 0;
}
8. Kasus 8
#include <iostream>
using namespace std;
int main(int argc, char *argv[])
{
float jumlah_es, jumlah_ayam, harga_total;
cout<<"Masukkan Jumlah Ayam Goreng = ";
cin>>jumlah_es;
cout<<"Masukkan Jumlah Es Teh = ";
cin>>jumlah_ayam;
cout<<"Harga Ayam Goreng = 15.000 \n";
cout<<"Harga Es Teh = 2.000 \n";
harga_total=2000*jumlah_es+15000*jumlah_ayam;
cout<<"Harga Total = "<<harga_total;
return 0;
}
9. Kasus 9
#include <iostream>
using namespace std;
int main()
{
char nama_depan[30],nama_belakang[30], nim[30];
float nt1, nt2, nt3, nt4, nt5, average;
//nt = nilai tugas
cout<<"Masukkan Nama : ";
cin>>nama_depan>>nama_belakang;
cout<<"Masukkan NIM : ";
cin>>nim;
cout<<"Masukkan Nilai Tugas 1 : ";
cin>>nt1;
cout<<"Masukkan Nilai Tugas 2 : ";
cin>>nt2;
cout<<"Masukkan Nilai Tugas 3 : ";
cin>>nt3;
cout<<"Masukkan Nilai Tugas 4 : ";
cin>>nt4;
cout<<"Masukkan Nilai Tugas 5 : ";
cin>>nt5;
average=(nt1+nt2+nt3+nt4+nt5)/5;
cout<<"\n";
cout<<"==============================================\n";
cout<<"Nama : "<<nama_depan<<nama_belakang<<"\n";
cout<<"NIM : "<<nim<<"\n";
cout<<"Nilai Tugas 1 : "<<nt1<<"\n";
cout<<"Nilai Tugas 2 : "<<nt2<<"\n";
