Solving a problem is meaningless if you can't convert it to a workable code in a contest that covers all the edge cases. Solving a problem, writing its code in an efficient language is a must for a problem solver. And currently, the fastest known coding language for a competitive programmer is undoubtedly C++. We will go through each C++ concepts needed for a competitive programmer in order to ace in contests and problem solving.

Who Can Join This Course?

Good logic sense. Familiarity with at least one programming language will even boost your learning, but it is not mandatory.

সবার প্রথমে মিনহাজুল ইসলাম শরীফ ভাইয়াকে ধন্যবাদ দিয়ে শুরু করতে চাই , ভাইয়ার প্রায় সাত বছর প্লাস কনটেস্ট প্রোগ্রামিং এর অভিজ্ঞতা আছে ভাইয়ার কাছে ক্লাস করার সময় মনে হচ্ছিল কোন পরিচিত বড় ভাইয়ের কাছে শিখতেছি তার ব্যবহার অনেক বন্ধু সুলভ , ভাইয়ার কাছে শিখেছি প্রোগ্রামিং মাইন্ডসেট । আমি মনে করি প্রোগ্রামিং শেখার আগে প্রোগ্রামিং মাইন্ডসেট সম্পর্কে ক্লিয়ার কনসেপ্ট রাখতে হবে কারণ আপনার মাইন্ডসেট যতক্ষণ পর্যন্ত ক্লিয়ার না থাকবে প্রোগ্রামিং সম্পর্কে lআপনি শেষ পর্যন্ত ধরে রাখতে পারবেন না শুরুতে অনেক আগ্রহ থাকে কিন্তু সময়ের সাথে তা হারিয়ে যায় তাই আমি মনে করি "একজন লার্নার এর কাছে প্রোগ্রামিং হচ্ছে একটা মাইন্ডসেট এবং ডিসিপ্লিন " আমাদের সিলেবাসের যা কিছু ছিল তা সবই শেষ করেছি কিন্তু সিলেবাসে ছিল না একজন প্রোগ্রামার এর ইন্টায়ারলাইভ জার্নি টা কেমন হবে ? আমাদের ইনস্ট্রাক্টর খুব সুন্দর করে আমাদের সামনে উপস্থাপন করেছে । ক্লাসের বাইরে এইসব তথ্য একজন বিগেনার জন্য খুবই গুরুত্বপূর্ণ l সব শেষে আবারো শরীফ ভাইকে ধন্যবাদ দিতে চাই কোর্স শেষ হওয়ার পরও আমাদের কে সাপোর্ট দেওয়ার জন্য।

This course is very helpful for those who's are going to start cp carrier. I have learned many topics that I don't know. Our instructor Sharif Minhazul Islam is very friendly and he teaches us every single topic very nicely. His problem solving technique also motivate me I highly recommended for these course.

The course was well organized and the syllabus was perfect. I definitely learned some new topics from the course. But because of my university pressure, I had to be irregular from the course and I regret this. The course teacher is a nice and kind person. He loves to teach and cooperate with the students. But I don't know why I felt a lack of energy in his voice. But he is a really nice and cooperative teacher. Maybe, I couldn't feel the learning enthusiasm. I would say if Devskill announces the specific teacher's name and information on who is going to conduct the specific batch before taking the registration, it would be nicer.

Our course teacher Sharif Minhazul Islam is very knowledgeable in Competitive Programming. He's also very helpful. The way he teaches is top-notch. I learned a lot from this course about C++ and competitive programming. For anyone who has never done any programming in life can also learn computer programming from this course.
