DIFFERENCE BETWEEN COMPILER AND INTERPRETER

DIFFERENCE BETWEEN COMPILER AND INTERPRETER
  •  The main difference between a compiler and an interpreter is that a compiler converts the entire source code to machine code or bytecode before execution, while an interpreter executes the source code line by line.

  • Execution Speed: A compiled program is usually faster than an interpreted program because the entire source code is translated into machine code or bytecode before execution, which eliminates the need for repeated translation of the code.

  • Memory Usage: An interpreter generally uses less memory than a compiled program because the interpreter only needs to keep track of the current line of code and the current state of the program, whereas a compiled program requires a separate executable file that is loaded into memory.

  • Portability: Interpreted languages are usually more portable than compiled languages because the interpreter can be run on any platform that supports it, whereas a compiled program must be compiled for each specific platform.

  • Debugging: Debugging an interpreted program is usually easier than debugging a compiled program because the interpreter can provide more detailed error messages and can execute the code one line at a time.

  • Development Time: Development time for an interpreted language is generally faster than for a compiled language because changes can be made and tested immediately without the need for recompilation.

  • Optimization: Compilers can perform more sophisticated optimization techniques than interpreters, which can result in faster and more efficient code.

  • Libraries: Compiled programs usually require linking to external libraries, while interpreted programs typically include libraries as part of the interpreter.

  • Interactivity: Interpreted languages are more interactive than compiled languages because they allow users to enter commands and see the results immediately.

  • Security: Interpreted languages are generally less secure than compiled languages because they allow access to the source code, which can be analyzed and exploited by attackers. Compiled languages, on the other hand, provide an extra layer of protection as the machine code is more difficult to reverse engineer.

INTRODUCTION TO LANGUAGES

 Introduction to Languages: The basic components of a computer are: Input unit Central Processing Unit(CPU) Output unit The CPU is further divided into three parts-   Memory unit  Control unit  Arithmetic Logic unit      Most of us have heard that the CPU is called the brain of our computer because it accepts data, provides temporary memory space to it until it is stored(saved) on the hard disk, performs logical operations on it, and hence processes(here also means converts) data into information.       We all know that a computer consists of hardware and software. Software is a set of programs that performs multiple tasks together. An operating system is also software (system software) that helps humans to interact with the computer system.      A program is a set of instructions given to a computer to perform a specific operation. or computer is a computational device that is used to process data under the control of a com...

 JAVA PROGRAMMING EXAMPLES Here are the programming examples of JAVA which are discussed in the video lecture of Advanced JAVA programming. Concept of Collection and Interface Introductory program import java.util.*; public class CollectionInterfaceExample {     public static void main(String[] args) {         // Creating a List         List<String> namesList = new ArrayList<>();         namesList.add("Yeshwant ");         namesList.add("Mahavidyalaya");         namesList.add("Nanded");         namesList.add("(MS)");         System.out.println("List elements:");         for (String name : namesList) {             System.out.println(name);         }         // Creating a Set         Set<Integer> numbersSet = n...

DECISION MAKING STATEMENTS IN C

Image
  Decision Making Statements : if, if else,nested if, switch statement if STATEMENT if is most basic statement of Decision making statement. It tells to program to execute a certain part of code only if particular condition or test is true. Syntax if(<condition>)     [ Statement or block of statements]; Example #include<stdio.h> #include<conio.h> void main() { int a=9; if(a<10) { printf(“a is less than 10”); } getch(); } Output a is less than 10 Constructing the body of "if" statement is always optional, Create the body when we are having multiple statements. For a single statement, it is not required to specify the body. If the body is not specified, then automatically condition part will be terminated with next semicolon ( ; ). if -else STATEMENT It is a keyword, by using this keyword we can create a alternative block for if part. Using else is always optional i.e, it is recommended to use when we are having alternate block of condition. In any prog...
