Computer Programming 1 - Introduction to Programming

It is a sequence of statements intended to accomplish a task. It is a set of instructions for a computer to follow.

​Programming

Is the process of creating a set of instructions that tell a computer how to perform a task. Programming can be done using a variety of computer programming languages, such as JavaScript, Python, and C++.

Computer Programming 1 - Introduction to Programming

​These are the languages that deal with a computer’s hardware

components. There are two (2) common low-level languages: machine language and assembly language.

• It is the language that the computer can directly understand. It is the most basic set of instructions that the computer can execute.

• Machine language programs are written into binary codes (0,1).

​

​Computer Programming 1 - Introduction to Programming

• It is a symbolic form of machine language that is easier for people to read, such as ADD AX DX. This makes use of instructions in mnemonic form.

​These are the programming languages that use natural languages, such as the English Language. A high-level language has its own syntax.​

rules of the language, for example, print or write is used to produce and output.​

• these are program statements that carry out tasks that the program has to perform, for example, print this word or add these two (2)numbers.

errors that occur when the syntax of the program is correct but the expected output is not.

high-level languages

It is a problem-solving technique used in solving programming problems. It is a step-by-step problem-solving process in which a solution is arrived at in a finite amount of time.

​​The problem-solving process in the programming environment involves the following steps:

1. Problem Analysis: Analyze the problem and outline the problem and its solution requirements.

2. Algorithm Design: Design an algorithm in a programming language.

3. Coding: implement the algorithm in a programming language.

4. Execution: Verify that the algorithm works.
