2. Analysis:

💎The existing system is evaluated. Deficiencies are identified. This can be done by interviewing users of the system and consulting with support personnel.

@Computer_science_course

3. Design:

💎The proposed system is designed. Plans are laid out concerning the physical construction, hardware, operating systems, programming, communications and security issues.


@Computer_science_course

4. Implementation

The project takes shape during the implementation phase. This phase involves the construction of the actual project result. Programmers are occupied with encoding, designers are involved in developing graphic material, contractors are building, the actual reorganisation takes place. It is during this phase that the project becomes visible to outsiders, to whom it may appear that the project has just begun. The implementation phase is the doing phase, and it is important to maintain the momentum.

💎Testing: All aspects of performance must be tested. If necessary, adjustments must be made at this stage. Tests performed by quality assurance (QA) teams may include systems integration and system testing.

💎Deployment: The system is incorporated in a production environment. This can be done in various ways. The new system can be phased in, according to application or location, and the old system gradually replaced. In some cases, it may be more cost-effective to shut down the old system and implement the new system all at once.

💎Upkeep and maintenance: This step involves changing and updating the system once it is in place. Hardware or software may need to be upgraded, replaced or changed in some way to better fit the needs of the end-users continuously. Users of the system should be kept up-to-date concerning the latest modifications and procedures.

MEME 😅😂 LOL

What Is an Algorithm?

💎Algorithm: an effective method expressed as a finite list of well-defined instructions for solving a
problem.

💎An algorithm is the list of instructions and rules that a computer needs to do to complete a task.

💎In essence, algorithms are simply a series of instructions that are followed, step by step, to do something useful or solve a problem.

@Computer_science_course

Design can be shown using algorithms.

An algorithm must possess the following properties:

💎finiteness: The algorithm must always terminate after a finite number of steps.

💎definiteness: Each step must be precisely defined; the actions to be carried out must be rigorously and
unambiguously specified for each case.

💎input: An algorithm has zero or more inputs, taken from a specified set of objects.

💎output: An algorithm has one or more outputs, which have a specified relation to the inputs.

💎effectiveness: All operations to be performed must be sufficiently basic that they can be done exactly
and in finite length.

@Computer_science_course

An algorithm may be expressed in a number of ways, including:

💎Natural language:
💎Pseudocode
💎Flow charts:

@Computer_science_course

Example 1 : 💎 An algorithm that checks lamp.

@Computer_science_course

Example 2 : 💎An algorithm that takes two numbers and finds the sum.


@Computer_science_course

Example 3: 💎An algorithm that list the multiplication table for a given number.


@Computer_science_course

2. Pseudo-code

💎fake and Informal language that helps programmers to plan an algorithm.

💎It is somewhat similar to everyday English with a feel of programming language.


@Computer_science_course

Example: 💎 a Pseudo-code for a program that calculates the factorial for a given number.

What is C++?

📌 C++ is a cross-platform language that can be used to create high-performance applications.

📌 C++ was developed by Bjarne Stroustrup, as an extension to the C language.

📌 C++ gives programmers a high level of control over system resources and memory.
