COMPILER DESIGN

Detailed explanation-1: -Program development life cycle (PDLC) The process containing the five phases of program development: analyzing, designing, coding, debugging and testing, and implementing and maintaining application software.

Detailed explanation-2: -In programming, sequence is a basic algorithm: A set of logical steps carried out in order. Computers need instructions in the form of an algorithm in order to complete a desired task, and this algorithm must have the correct order of steps, or sequence.

Detailed explanation-3: -The first step is to examine the problem carefully to try to identify what qualifies as a solution. A single problem may have many different solutions, but they will all have something in common. So here you’re trying to work out exactly what your program will be required to do. and display the result for the user.

Detailed explanation-4: -Just like the sequence of events in a story, sequencing in programming is all about the order of the instructions. It’s about deciding which step comes first, second, third, and so on. It’s imperative to get the order right, or you could end up with a code that doesn’t work or does something entirely unexpected.
