How can i be good at c++? what are the tasks or challenges that beginners should try for improving their quality of code?

Answer 1

Everyday. Every spare minute. No t.v. no parties. In other words... get a thick notebook and take tons of notes or use another computer to be your notebook. And don't rush through anything. Take your time and practice, practice, practice coding until you FULLY UNDERSTAND the parts you are studying. Most of all...ENJOY! And before you know it you'll be a programmer that only needs to see the doc page of the language you're studying. Remember. One language at a time and one you like. Best of luck to you.
