 Deklarasi banyak,i,x
array int nilai [20]
deklarasi string nama

inputkan banyak mahasiswa
for (int i=1;i<=banyak;i++){
input nama;
input nilai mahasiswa i
if (nilai[20]>=80 || nilai[20]<=100)
ceta nilai = A
else if (nilai[20]>=60 || nilai[20]<80)
cetak nilai = B
else if (nilai[20]>=40 || nilai[20]<60)
cetak nilai = C
else if (nilai[20]>=20 || nilai[20]<40)
cetak nilai = D
else if (nilai[20]>=0 || nilai[20]<20)
cetak nilai = E
end for

CPP nya :
#include <iostream> /* run this program using the console pauser or add your own getch, system("pause") or input loop */ using namespace std; int main(int argc, char** argv) { int banyak, i,x; int nilai[20]; string nama; cout<<"Masukan Banyak Mahasiswa :"; cin>>banyak; for (int i=1;i<=banyak;i++){ cout<<"nama Mahasiswa :";cin>>nama; cout<<"Masukan nilai :";cin>>nilai[20]; if (nilai[20]>=80 || nilai[20]<=100){ cout<<"\n Nilai "<<nilai[20]<<"Adalah A"; } else if (nilai[20]>=60 || nilai[20]<80){ cout<<"\n Nilai "<<nilai[20]<<"Adalah B"; } else if (nilai[20]>=40 || nilai[20]<60){ cout<<"\n Nilai "<<nilai[20]<<"Adalah C"; } else if (nilai[20]>=20 || nilai[20]<40){ cout<<"\n Nilai "<<nilai[20]<<"Adalah D"; } else if (nilai[20]>=0 || nilai[20]<20){ cout<<"\n Nilai "<<nilai[20]<<"Adalah E"; } cout<<"\n========================================================================\n"; } return 0; }
