Detailed explanation-1: -Structured programming is a programming paradigm aimed at improving the clarity, quality, and development time of a computer program by making extensive use of the structured control flow constructs of selection (if/then/else) and repetition (while and for), block structures, and subroutines.
Detailed explanation-2: -Structure Rule Two: Sequence A sequence of blocks is correct if the exit conditions of each block match the entry conditions of the following block. Execution enters each block at the block’s entry point and leaves through the block’s exit point.
Detailed explanation-3: -Top-down approach is followed in structural programming. Explanation: The statement is true. Structural programming follows the top – down approach. Each module is further divided into sub modules.
Detailed explanation-4: -Rule 1 of Structured Programming: A code block is structured. In flow charting terms, a box with a single entry point and single exit point is structured. This may look obvious, but that is the idea. Structured programming is a way of making it obvious that program is correct.
