Evolution of Programming Languages: From Machine Language to High-Level Languages, Essays (university) of Programming Languages
An overview of the evolution of programming languages, starting from machine language and moving on to high-level languages. It covers the concepts of interpreters, compilers, and translators, and introduces the python programming language. Students will learn about the differences between low-level and high-level languages, as well as the various paradigms of programming. The document also includes examples of code in machine language, assembly language, and high-level languages (c and python), and discusses the advantages of functional programming.

Objectives
Describe the evolution of programming languages from machine language to high-level languages. ❑ Understand how a program in a high-level language is translated into machine language using an interpreter or a compiler. ❑ Learn about computer language paradigms. ❑ Introducing Python programming and arithmetic expressions ❑
Introduction
Introduction To write a program for a computer, we must use a computer language. A computer language is a set of predefined words that are combined into a program according to predefined rules (syntax). Over the years, computer languages have evolved from machine language to assembly languages to high-level languages.

Programming language: A set of rules, words, symbols,
and codes used to write computer programs
To write a program, you need appropriate software for the programming language you will be using 7

Categories of programming languages
Low-level languages: Difficult to code in; machine
dependent
Machine language: 1 s and 0 s Assembly language: Includes some names and other symbols to replace some of the 1 s and 0 s in machine language High-level languages: Closer to natural languages Machine independent Includes 3 GLs (FORTRAN, BASIC, COBOL,C, etc.) and object-oriented languages (Visual Basic, C#, Python, Java, etc.) Visual or graphical languages: Use graphical interface to create programs 8

Code in High Level Languages (in C)
#include <stdio.h>
int main( )
int num1, num2, sum;
printf("Enter two integers: ");
scanf("%d %d",&num1,&num2);
sum=num1+num2;
printf("Sum: %d",sum);
return 0;
Code in High Level Languages (in Python)
print("Enter two integers: ")
num1=int(input())
num2=int(input())
sum=num1+num
print("Sum: ", sum)

Translators
Translation
- Programs today are normally written in one of the high-level languages.
- To run the program on a computer, the program needs to be translated into the machine language of the computer on which it will run.
- The program in a high-level language is called the source program.
- The translated program in machine language is called the object program.
