4. Introduction to Programming? Definition of Programming? Is the art of writing computer programs. What is Programming Language? A programming language is a language that a computer can understand and provides a programmer an environment to write and execute programs in it . Examples of Computer Languages C, C ++, Java, Ajax, Fortran, Pascal, Ruby etc

5. Generations in Computer Languages First Generation : Machine Language, is a language that consists of 1’s and 0’s Second Generation: Assembler language consisting of instructions like LOAD, ADD Third Generation: High level language (HLL) a bit easy to understand e.g. C, C ++, J ava, C obol 4GL: equivalent to human specific language e.g. SELECT NAME FROM RECORDS WHERE NAME=“JOHN”;

6. Types of Programming Languages Read and make your own notes on the types of programming languages ? Procedural Programming Languages : Object-Oriented Programming Languages : Scripting Programming Languages :

7. Definition of Key Terms: Syntax: Syntax of a programming language means the rules that dictate how exactly the vocabulary elements of the language can be combined to form statements . Semantics: The semantics of a statement in a programming language define what will happen when that statement is executed. In other words, semantics refer to the meaning of the statement . Program Errors: Errors associated with computer Programs

8. Types of Programming Errors Logical errors: The program runs, compiles normally but produces wrong results . Runtime errors: Occur during execution of a computer program and cause program to abort abnormally. E.g. infinite looping or division by zero Compile time errors: E rrors that are identified at compile time using the compiler, they include syntax and wrong data types

9. Program Development & Top Down Design During Program development, the following steps must be followed: Understand the problem Analyzing the problem we're given Dissect the problem into manageable pieces Developing a solution technique (algorithm) Documenting the program/technique Translating (implementing) the technique into code Compiling and running the program Testing the results with appropriate data

10. What is Top down Approach? Take a problem, divide it into smaller logical sub-problems, and remember how they fit together. For each sub-problem, divide it into still smaller sub-problems. Continue sub-dividing until each little problem is small enough to be easily solved. Solving a collection of small problems thus allows us to solve one much larger problem.
