Final answer:
A structured program in computer science consists of sequence, selection, and iteration structures, which form the basis for all logical program algorithms and efficient software development.
Step-by-step explanation:
A structured program includes only combinations of the three basic structures: sequence, selection, and iteration. These are fundamental constructs in the field of computer science and are used to create more complex algorithms and programs. The sequence structure refers to executing statements one after another, in the order they appear. Selection involves making decisions and executing different code branches based on conditions, often represented by if-else statements. Lastly, iteration is the repetition of a block of code, commonly done through loops such as for-loops or while-loops.
Understanding these three structures is vital in computer programming as they enable programmers to control the flow of execution and build logical solutions to problems. By thoroughly grasping these concepts, one can develop efficient and effective programs, making them fundamental building blocks in the realm of software development
