How can we develop the logic used in programming???

Answer 1

before starting coding, pick pen and paper and note down the key points of problem and try to minimize the steps. then put that points into algorithm then program it.

it will increase your logic.

Answer 2

Practice and reference. Don't be reluctant to refer to how other people solve problems. You can come up with your own algorithm to solve a specific task (and it can be rewarding), but it is as fine to learn algorithms from other sources and apply it to solve your problems.
