Program C++ Konversi suhu

Buka aplikasi DEV-C++ lalu salin source code dibawah ini:

 

#include<iostream>

using namespace std;

 

int main(){

              cout<<"Konversi suhu"<<endl;

             

              double celcius, kelvin, farenheit, hasil;

              cout<<"pilih jenis suhu:\n [1. celcius]\n [2.kelvin]\n [3.fahrenheit]\n masukkan jenis suhu : ";

              cin>>pilih;

//           jenis suhu yg di inginkan

    if(pilih == 1){

//           CELCIUS

              cout<<endl;

              cout<<"[celcius]\nsuhu yang mau di konversikan \n [1.kelvin]\n [2.fahrenheit]\n suhu : ";cin>>celcius2;

Membuat kalkulator berbasis web

     Pertama buat dulu 1 file tipe .html lalu copy source code dibawah :

<!DOCTYPE html>

<html>

    <head>

        <title>Kalkulator sederhana</title>

    </head>

    <body>

        <form name="kalkulator">

            <table border="1">

                <th colspan="2">Kalkulator sederhana berbasis web</th>

                <tr>

                    <td>masukkan angka 1 : </td>

                    <td><input type="text" name="angka1" id="angka1"></td>

                </tr>

                <tr>

                    <td>masukkan angka 2 : </td>

                    <td><input type="text" name="angka2" id="angka2"></td>

                </tr>

                <tr>

                    <td>pilih operator [+, -, /, *] : </td>

                    <td><input type="text" name="operator" id="operator"></td>

                </tr>

                <tr>

                    <td colspan="0"><input type="button" value="submit" onclick="proses();"></td>

                    <td><p id="demo"></p></td>

                </tr>

            </table>

        </form>

    <script src="kalkulator.js" lang="javascript"></script>

    </body>

</html>

jika sudah maka buat lagi 1 file dengan tipe .js lalu copy isi source code dibawah :

function proses() {

    var angka1 = parseInt( kalkulator.angka1.value);

    var angka2 = parseInt( kalkulator.angka2.value);

    var operator = kalkulator.operator.value;

    var hasil = parseInt("");

    if (operator == '+') {

        hasil = angka1 + angka2;

        document.getElementById("demo").innerHTML = hasil;

    } else if (operator == '-') {

        hasil = angka1 - angka2;

        if (angka1 < angka2) {

            alert("angka1 harus lebih besar dari angka2");

        } else {

            document.getElementById("demo").innerHTML = hasil;

        }

    } else if (operator == '*') {

        hasil = angka1 * angka2;

        document.getElementById("demo").innerHTML = hasil;

    } else if (operator == '/') {

        hasil = angka1 / angka2;

        document.getElementById("demo").innerHTML = hasil;

    }

}
