Soal-soal Latihan Array Borland C++ (Tutorial)

Bagi rekan-rekan Ay-TI yang ingin belajar mendalami pemrograman C++, berikut ini saya posting contoh soal latihan untuk pemrograman C++ .
Silahkan di pelajari yaa,
Lumayan Buat Belajar Latihan Soal biar nanti pas UAS kagak pada nyontek atau nge'BED  :D.


Dibawah ini adalah soal2 latihan pra UAS Manajemen Informatika ataupun Komputer Akuntansi,

semoga bisa membantu rekan-rekan semua.
