Introduction
To ensure a clear and logical approach before coding, computer program planning involves defining the problem, designing a solution, and outlining the steps using tools like flowcharts, algorithms, and pseudocode.
Concept of Problem Solving
The process of recognizing and overcoming problems or challenges is known as problem-solving. It includes determining the issue, obtaining data, coming up with solutions, analyzing the options, and putting the best one into action.
Essential Elements of Solving Problems:
Problem Identification:
Problem identification is the process of identifying and precisely defining the problem or difficulty.
Information Gathering:
Compiling pertinent facts, figures, and information to comprehend the background of the issue.
Solution Generation:
Solution generation is the process of generating ideas and creating possible methods or solutions.
Evaluation and Selection:
Evaluating each solution's viability, efficacy, and any repercussions. Implementation: Putting the selected course of action into practice while keeping an eye on its effects.
Problem Definition
In computer science, "problem definition" refers to the act of properly expressing a particular problem within the solution space. Determining the starting state, the desired state, and the state transformations necessary to arrive at the ultimate solution are all part of it.
This is the initial stage of program development. This helps us comprehend the issue that needs to be addressed by the program. That is, the problem is identified and comprehended in this. The problem is formally defined in this step. This covers every aspect, including input/output, memory and processing requirements, error handling, and more.
Important Elements of the Problem Definition:
Statement of the Problem:
A succinct and understandable explanation of the issue that has to be resolved.
Inputs and Outputs:
Defining what the program will accept as input and what it should generate as output is known as inputs and outputs.
Constraints:
Determining any restrictions or limitations on the issue, like memory, time, or resource limitations.
Assumptions:
Any presumptions regarding the input data, output data, or the issue at hand should be stated explicitly.
Expected Behavior:
Outlining the program's expected behavior, including how to handle failures and edge cases.
