Lecture01Xafran

Computer is a programmable machine that can store, process, and retrieve data under the control of instructions. It consists of hardware and software. There are six logical units in every computer: input, output, memory, CPU, ALU, and secondary storage. Computer languages include machine language, assembly language, and high-level languages like C++. A C++ program goes through editing, preprocessing, compiling, linking, loading, and execution phases. Programs are made up of definitions, declarations, and functions to solve problems in a structured manner. Testing and debugging is done to eliminate bugs and logic errors in programs.

Function C programmingAppili Vamsi Krishna

The document discusses C functions, including their definition, types, uses, and implementation. It notes that C functions allow large programs to be broken down into smaller, reusable blocks of code. There are two types of functions - library functions and user-defined functions. Functions are declared with a return type, name, and parameters. They are defined with a body of code between curly braces. Functions can be called within a program and allow code to be executed modularly and reused. Parameters can be passed by value or by reference. Functions can return values or not, and may or may not accept parameters. Overall, functions are a fundamental building block of C that improve code organization, reusability, and maintenance.

Here are the key points about scanf(): - scanf() is used to read/input values from the keyboard or standard input device. - It follows the same format specifier conventions as printf() for data types (%d for int, %f for float, %c for char etc). - The address of operator & is used before variables in the argument list to tell scanf() to store the input directly into the memory location of the variables. - This is necessary because normally function arguments in C are passed by value, so scanf() would just get a copy of the variable instead of modifying the original one. The & takes the address to allow direct modification. So in summary, scanf

The document discusses loops in computer programming. It defines loops as blocks of code that are repeatedly executed. There are two main types of loops: counter-controlled loops, where the number of iterations is defined in advance, and sentinel-controlled loops, where the number depends on a condition. Common loop structures in C include the for, while, and do-while loops. The for loop allows predefined or open-ended repetition. The while loop executes until a condition is false. The do-while loop guarantees at least one iteration even if the condition is initially false.

Mesics lecture 4 c operators and experssionseShikshak

Operators in C allow operations to be performed on operands. Common operators include arithmetic, relational, logical, and bitwise operators. Operators have precedence and associativity that determine the order of operations. The conditional operator (?:) evaluates a condition and returns one of two expressions. Operators are used to perform calculations, comparisons, assignments, and logical tests in C programs.

Mesics lecture 5 input – output in ‘c’eShikshak

1. There are two main ways to handle input-output in C - formatted functions like printf() and scanf() which require format specifiers, and unformatted functions like getchar() and putchar() which work only with characters. 2. Formatted functions allow formatting of different data types like integers, floats, and strings. Unformatted functions only work with characters. 3. Common formatted functions include printf() for output and scanf() for input. printf() outputs data according to format specifiers, while scanf() reads input and stores it in variables based on specifiers.

Mesics lecture 3 c – constants and variableseShikshak

The document discusses various types of constants and variables in C programming. It describes primary constants like integer, real, and character constants and defines rules for constructing each type. Secondary constants include arrays, pointers, structures, and unions. Variables represent unknown values that can change during program execution. The document outlines naming conventions and rules for defining variables. It also covers C data types like integer, floating point, characters, and void and provides details on their sizes and ranges. Initialization of variables through assignment at declaration or dynamically at runtime is also summarized.

Lecture18 structurein c.ppteShikshak

The document discusses structures in C programming. It defines a structure as a collection of variables of different data types grouped together under a single name. Structures allow programmers to create custom data types by combining existing types. The document provides examples of defining, declaring, initializing and accessing members of structures, and also discusses arrays of structures and nested structures.

AI Changes Everything – Talk at Cardiff Metropolitan University, 29th April 2...Alan Dix

Talk at the final event of Data Fusion Dynamics: A Collaborative UK-Saudi Initiative in Cybersecurity and Artificial Intelligence funded by the British Council UK-Saudi Challenge Fund 2024, Cardiff Metropolitan University, 29th April 2025 https://alandix.com/academic/talks/CMet2025-AI-Changes-Everything/ Is AI just another technology, or does it fundamentally change the way we live and think? Every technology has a direct impact with micro-ethical consequences, some good, some bad. However more profound are the ways in which some technologies reshape the very fabric of society with macro-ethical impacts. The invention of the stirrup revolutionised mounted combat, but as a side effect gave rise to the feudal system, which still shapes politics today. The internal combustion engine offers personal freedom and creates pollution, but has also transformed the nature of urban planning and international trade. When we look at AI the micro-ethical issues, such as bias, are most obvious, but the macro-ethical challenges may be greater. At a micro-ethical level AI has the potential to deepen social, ethnic and gender bias, issues I have warned about since the early 1990s! It is also being used increasingly on the battlefield. However, it also offers amazing opportunities in health and educations, as the recent Nobel prizes for the developers of AlphaFold illustrate. More radically, the need to encode ethics acts as a mirror to surface essential ethical problems and conflicts. At the macro-ethical level, by the early 2000s digital technology had already begun to undermine sovereignty (e.g. gambling), market economics (through network effects and emergent monopolies), and the very meaning of money. Modern AI is the child of big data, big computation and ultimately big business, intensifying the inherent tendency of digital technology to concentrate power. AI is already unravelling the fundamentals of the social, political and economic world around us, but this is a world that needs radical reimagining to overcome the global environmental and human challenges that confront us. Our challenge is whether to let the threads fall as they may, or to use them to weave a better future.

1. www.eshikshak.co.in

2. Popularity of ‘C’ ● Robust ● Efficient and fast ● Portable ● Structured Programming www.eshikshak.co.in

3. Character Set ● A character can a number, alphabet, or any special symbol to represent information Alphabets A, B, ….., Y, Z a, b, ……, y, z Digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 Special symbols ~ ‘ ! @ # % ^ & * ( ) _ - + = |{}[]:;"'<>,.?/ www.eshikshak.co.in

4. Constants, Variables and Keywords ● A combination of character set’s numbers, alphabets and special symbols forms constants or variable or keywords Alphabets, Numbers and Special Symbols Constants Variables Keywords www.eshikshak.co.in

5. Constants ● A value that does not change during the execution of programming. Constants Primary Secondary Constants Constants www.eshikshak.co.in

6. Variables ● Variables in C have the same meaning as variables in algebra. That is, they represent some unknown, or variable, value. x=a+b z + 2 = 3(y - 5) ● Remember that variables in algebra are represented by a single alphabetic character. www.eshikshak.co.in

7. Keywords auto double int struct break else long switch case enum register typedef char extern return union const float short unsigned continue for signed void default goto sizeof volatile do if static while www.eshikshak.co.in

8. Program Structure in C ● EACH complete C program is composed of: ● Comment statements ● Pre-processor directives ● Declaration statements ● One or more functions ● Executable statements www.eshikshak.co.in

9. C Syntax and Hello World #include inserts another file. “.h” files are called “header” files. They contain stuff needed to interface to libraries and code in other “.c” files. Can your program have What do the < > more than one .c file? mean? This is a comment. The compiler ignores this. #include <stdio.h> The main() function is always /* The simplest C Program */ where your program starts int main(int argc, char **argv) running. { Blocks of code (“lexical printf(“Hello Worldn”); scopes”) are marked by { … } return 0; } Return ‘0’ from this function Print out a message. ‘n’ means “new line”. www.eshikshak.co.in

10. Comment Statements ● Formal Comments: /* Comment ….. */ ● Used for detailed description of functions or operations (for our benefit, not compiler’s). ● Can take multiple lines in source file. www.eshikshak.co.in

11. Pre-Processor Directives #include -- header files for library functions Example: #include <stdio.h> Note Space #define -- define constants and macros Examples: #define e 2.7182818 #define pi 3.14159265359 Note Spaces www.eshikshak.co.in

12. Declarations ● Declarations tell the compiler what variable names will be used and what type of data each can handle (store). ● Example declarations: int a, b, c ; float r, p, q ; double x, y, z ; char m, n ; www.eshikshak.co.in
