Well now I will tell u the way how to create a data c ++ is an index !!!!
ok we live can make learning cauuuuuuu also thanks !!!!

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

using namespace std;

int main ()
{
    jml1 float, jml2, jml3, jml4, end, UTS, UAS, assignments, quizzes;
    cout << "unikdata44.blogspot.com" << endl;
    cout << "Do not forget to end with a semicolon" << endl;
    cout << "Enter the value of UTS:";
    cin >> uts;
    cout << "Enter the value of UAS";
    cin >> lever;
    cout << "Enter the value TASKS";
    cin >> task;
    cout << "Enter the value QUIZ:";
    cin >> quiz;
    cout << endl;
    jml1 = uts * 35/100;
    jml2 = UAS * 35/100;
    jml3 = task * 10/100;
    jml4 = quiz * 20/100;
    cout << "UTS (35%):" << endl << jml1;
    cout << "UAS (35%):" << endl << jml2;
    cout << "DUTY (10%):" << endl << jml3;
    cout << "QUIZ (20%):" << endl << jml4;
    end = jml1 + jml2 + jml3 + jml4;
    cout << "The final value is" jml1 << << "" << jml2 << "" << jml3 << "" << jml4 << "" << endl << end;
    cout << "Value index you are";
    if (end> = 85 && end <= 100) {
        cout << "A" << endl;
    } Else if (end> = 70 && end <85) {
        cout << "B" << endl;
    } Else if (end> = 50 && end <70) {
        cout << "C" << endl;
    } Else if (end> = 40 && end <50) {
        cout << "D" << endl;
    } Else {
        cout << "E" << endl;
    }
    getch ();
    return 0;
}

Nah sekarang gua bakal kasih program peminjaman buku
Jangan lupa lu setiap memulai membbuat "include" soalnya gua pernah lupa nulis dan alhasilnya...

GAGAL ( ERROR ) !!!!
langsung aja ke pelajarannya !!


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

using namespace std;

int main()
{
    system("color f0"); // ini kenapa gua pakai syste color soalnya gua mau bikin latar background white
    int jml, total;
    char pil;
    cout << "====================\n";
    cout << "TUGAS JURNAL NOMOR 2\n";
    cout << "  Harga Sewa Komik  \n";
    cout << "====================\n\n";
    cout << "Masukan Jenis Member <A/B/C> : ";
    cin >> pil;
    cout << "Masukan Jumlah Komik : ";
    cin >> jml;
    if(pil=='a' || pil == 'A'){
        if(jml < 5 && jml > 0){
            total = jml * 1000;
            cout << "Harga total adalah : Rp." << total << endl;
        }else if( jml  >= 5 && jml < 10){
            total = jml *  500;
            cout << "Harga total adalah : Rp." << total << endl;
        }else{
            total = jml * 250;
            cout << "Harga total adalah : Rp." << total << endl;
        }
    }else if(pil == 'b' || pil == 'B'){
        if(jml < 5 && jml > 0){
            total = jml * 2000;
            cout << "Harga total adalah : Rp." << total << endl;
        }else if( jml  >= 5 && jml < 10){
            total = jml * 1000;
            cout << "Harga total adalah : Rp." << total << endl;
        }else{
            total = jml * 500;
            cout << "Harga total adalah : Rp." << total << endl;
        }
    }else if(pil == 'c' || pil == 'C'){
        if(jml < 5 && jml > 0){
            total = jml * 5000;
            cout << "Harga total adalah : Rp." << total << endl;
        }else if( jml  >= 5 && jml < 10){
            total = jml * 2500;
            cout << "Harga total adalah : Rp." << total << endl;
        }else{
            total = jml * 1000;
            cout << "Harga total adalah : Rp." << total << endl;
        }
    }else{
        cout << "Maaf kode member tidak valid" << endl;
    }
    getch();
    return 0;
}

simak aja gan kali aja bisa bantu !!!

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

using namespace std;;

int main()
{
    system("color f0");
    int angka;

    cout << "====================" << endl;
    cout << "TUGAS JURNAL NOMOR 1" << endl;
    cout << "   Kelipatan Angka  " << endl;
    cout << "====================" << endl;

    cout << "Masukan angka : ";
    cin >> angka;
    if(angka%3==0){
        cout << "Angka " << angka << " merupakan kelipatan 3" << endl;
    }else if(angka%7==0){
        cout << "Angka " << angka << " merupakan kelipatan 7" << endl;
    }else{
        cout<<"Angka bukan kelipatan 3 atau 7";
    }
    getch();
    return 0;
}
