របៀបហៅអនុគមន៏ Calling Function

អនុគមន៏ប្រៀបបានជាកូនកម្មវិធីដែលគេចងក្រងឡើងដើម្បីងាយស្រួលក្នុងការហៅវាមកប្រើប្រាស់វិញក្នុងកម្មវិធីដែលបង្កើតឡើងដោយអ្នកសរសេរកម្មវិធី។ថ្ងៃនេះខ្ញុំនឹងយកការហៅអនុគមន៏មួយចំនួនមកធ្វើការបង្ហាញជូន។

ខ្ញុំនឹងបង្កើតកម្មវិធីមួយសម្រាប់ទាញយកអនុគមន៏មកធ្វើការគណនាដូចជា៖
បើខ្ញុំចុចលេខមួយណាវានឹងទាញយកអនុគមន៏ដើម្បីធ្វើការគណនាៈ

8. រកបូកស្វីនៃចំនួនសេស
9. រកចំនួនហ្វាក់តូយែល Factorial
10. អត្រាប្តូរលុយពីរៀលទៅដុល្លា ឬ ដុល្លាទៅរៀល។

ជាដំបូងយើងត្រូវបង្កើតកូដនៃការគណនាទាំងអស់ជាអនុគមន៏មួយជាមុនសិន។
