ভাইয়া এখানে আমার একটা প্রশ্ন আছে। Radius এর বর্গ করার জন্য এখানে ব্যবহৃত হয়েছে radius * radius. কিন্তু সুত্র টার গঠন হচ্ছেঃ
3.1416 * radius * radius
আমার জিজ্ঞাস্য হচ্ছে এমন কি হতে পারে যে 3.1416 এর সাথে প্রথম radius ভ্যালু এর গুন হবার পরে তারপর দ্বিতীয়বার radius এর ভ্যালুর সাথে গুনটা হচ্ছে? যেহেতু আমরা জানি প্রোগ্রামিং এর প্রবাহ উপর থেকে নিচের দিকে ধাবিত হয় তাই প্রথমে ৩.১৪১৬ এর সাথে রেডিয়াস এর গুন হবার কথা।
বীজগনিতে আমরা ( ) ব্যবহার করে এটা সমাধান করে থাকি কিন্তু এক্ষেত্রে তো ( ) ব্যবহার হয়নি। আশা করি বোঝাতে পেরেছি। ধন্যবাদ এত সুন্দর টিউটোরিয়াল উপহার দেয়ার জন্য।
