Final answer:
A structured program consists of sequence, selection, and loop structures in computer programming.
Step-by-step explanation:
A structured program, in the context of computer programming, refers to a program that is organized and written in a systematic manner. It typically consists of three main structures - sequence, selection, and loop.
The sequence structure is the simplest structure and represents the order in which the instructions or statements are executed. It follows a straight-line flow where one statement is executed after another.
The selection structure allows the program to make decisions based on certain conditions. This is done using if statements, if-else statements, or switch statements to selectively execute code blocks.
The loop structure allows for the repetition of a certain block of code until a particular condition is met. There are different types of loops like for loop, while loop, and do-while loop for achieving different kinds of repetition.
