In software engineering there are two approaches which are followed by coding techniques

Structured programming techniques:-

In this programming approach codes are given some structures, it involves writing codes in blocks. It involves extensive use of selection (branching statement like if-else, case), sequence (line by line commands) and repetition (use of for loop, while, do-while) of blocks.

It breaks down larger programs into smaller so that it executes some task.

Procedural programming technique:-

It shares same features as structured but it implements procedural or subroutines to execute common functionality.
