    Code:

    ++

    ) dan penurunan (

    Code:

    —

    ).Tabel Operator penaikan dan penurunanOperatorKeteranganPenjabaranOperator penaikan (

    Code:

    ++

    ) berfungsi untuk menambahkan 

    Code:

    1

     nilai kepada nilai tujuan dan Operator penurunan (

    Code:

    —

    ) berfungsi untuk mengurangi 

    Code:

    1

     nilai pada nilai tujuan.Contoh :

    [table]

    [tr]

    [/tr]

    [/table]

    [td]12[/td][td]

    Code:

    int

    Code:

    x = 1 ;

    Code:

    x++;

    [/td]

    Contoh di atas adalah contoh bagaimana operator penaikan di gunakan, nilai 

    Code:

    x

     yang telah diinisialisasi dengan nilai 

    Code:

    1

     akan ditambahkan dengan nilai 

    Code:

    1

     dan menjadi 

    Code:

    2

     setelah menggunakan operator penaikan, dan juga sebaliknya jika mnggunakan operator penurunan.Cara kerja dari operator penaikan dan penurunan akan berbeda tergantung dari peletakanya, tanda operator penaikan atau penurunan dapat diletakan di depan operand (Prefix) atau di belakang operand (Postfix).

    Code:

    ++X

     (Prefix) adalah Nilai variabel 

    Code:

    X

     dinaikan dahulu sebelum diproses.

    Code:

    X++

     (Postfix) adalah Nilai variabel 

    Code:

    X

     diproses dahulu sebelum dinaikan.Contoh Program :

    [table]

    [tr]

    [/tr]

    [/table]

    [td]
    [/td]    		[td]
