Competitive Programming - Beginner - B12
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.

What Students Said

Competitive programming is very important to improve logic building skills. I try to attend every class. I believe, if anyone practice regularly and consistently, he/she will improve In Sha Allah. Though I have some lack of solving problems in online judge, but I have been trying. The instructor was very helpful. Thank you Dev Skill and the instructor for the amazing course and providing a platform to learn programming.

Course is great, course teacher Sharif Minhazul Islam is one of the best teachers. I have learned a lot of from this course, which helps me learn about many new terms, clear our doubts, how to solved a problem, and many other things. Specially the teacher cleared the concepts so well that we did not have any difficulty in understanding them. This course is so helpful

The instructor is a fascinating mentor. Even though I have basic concepts but I had a gap. He cleared my concepts. I believe he'll help me even going forward. I wish for all the best.
