Presentation 2.pptx
Presentation 2.pptxziyadaslanbey The document discusses functions in C programming. It defines functions as basic building blocks that contain a set of programming statements enclosed in curly braces. Functions provide reusability and modularity to programs. The key advantages of functions are reusability, which avoids rewriting code, and abstraction, which hides implementation details. There are two types of functions - library functions declared in header files and user-defined functions created by the programmer. Functions can return a value or not, and may or may not accept arguments.
C functions
C functionsUniversity of Potsdam A function is a group of statements that together perform a task. Every C program has at least one function, which is main(), and all the most trivial programs can define additional functions. You can divide up your code into separate functions.
CHAPTER THREE FUNCTION.pptx
CHAPTER THREE FUNCTION.pptxGebruGetachew2 Functions allow programmers to organize code into reusable blocks. A function is defined with a return type, name, parameters, and body. Functions can be called to execute their code from other parts of a program. Parameters allow data to be passed into functions, and functions can return data through return values or by reference. Inline functions avoid function call overhead by copying the function code into the calling location. Default parameters simplify function calls by automatically passing default values if arguments are omitted.
Chapter One Function.pptx
Chapter One Function.pptxmiki304759 This document provides an overview of functions in C++. It defines what a function is, how to declare and define functions, how to call functions, and the differences between passing arguments by value versus by reference. A function is a block of code that performs a specific task. Functions are declared with a return type and parameter list, and defined with a body of code. Arguments can be passed into functions either by value, where the function receives a copy of the argument, or by reference, where any changes to the argument are reflected in the original variable. Well-designed programs use modular functions to organize code into reusable components.

- Functions allow code to be modularized and reused, improving readability, debugging, and maintenance.
- A function prototype declares a function's name, return type, and parameters so it can be called before defining the implementation.
- Functions are divided into four main types based on whether they accept arguments, return values, or both. The most common type allows two-way communication by accepting arguments from the calling function and returning a value.
- When a function is called, its code is executed using copies of any arguments
Introduction to c programming
Introduction to c programmingAMAN ANAND This document provides an introduction to functions in C programming, including their motivation and benefits, syntax, components, operation, and data passing mechanisms. Functions allow code to be reused in different parts of a program or across multiple programs. They separate code into independent and reusable parts. The general syntax of a function includes its return type, name, parameters, and body. Functions are called by name with actual parameters passed in. They return control and any return value back to the calling function. Arrays can be passed to functions, which are effectively passed by reference so changes made in the function affect the original array.

Chap 5 c++
Chap 5 c++Venkateswarlu Vuggam The document discusses different types of storage classes in C++ that determine the lifetime and scope of variables:
1. Local variables are defined inside functions and have scope limited to that function. They are destroyed when the function exits.
2. Global variables are defined outside all functions and have scope in the entire program. They are destroyed when the program ends.
3. Static local variables are local variables that retain their value between function calls. Register variables are local variables stored in processor registers for faster access.
4. Thread local storage allows defining variables that are local to each thread and retain their values similar to static variables. The document provides examples to illustrate local, global, and static variables.

Building Security Systems in Architecture.pdf
Building Security Systems in Architecture.pdfrabiaatif2 Building security systems are essential for protecting people, property, and assets within a structure. These systems include a range of technologies and strategies such as surveillance cameras (CCTV), access control systems, alarm systems, security lighting, and motion detectors. Modern security solutions often integrate smart technology, allowing remote monitoring and real-time alerts through mobile devices. Access control systems, like key cards or biometric scanners, ensure that only authorized individuals can enter certain areas, enhancing both safety and privacy. Alarm systems, whether triggered by unauthorized entry, fire, or environmental hazards, play a critical role in emergency response. Additionally, video surveillance acts as both a deterrent and a tool for investigating incidents. An effective building security system is carefully planned during the design phase, taking into account the building's size, purpose, and potential risks. Ultimately, robust security systems are vital for ensuring peace of mind, protecting lives, and preserving valuable assets.

Functions in c++, presentation, short and sweet presentation, and details of functions
- 2. Function Dividing a program into functions. ■ a major principle of top-down, structured programming. ■ To reduce the size of the program. ■ Code re-use. ■ Like C++ operators, a C++ function can be overloaded to make it perform different tasks depending on the arguments passed to it.
- 3. Introduction Void show(); /* Function declaration */ void main() { show(); /* Function call */ } void show() /* Function definition */ { /* Function body */ }
- 4. The main() Function The main() returns a value of type int to the operating system by default. The functions that have a return value should use the return statement for termination. Use void main(), if the function is not returning any value.
- 5. Function Prototyping The prototype describes the function interface to the compiler by giving details such as: The number and type of arguments The type of return values. ■ It is a template ■ When the function is called, the compiler uses the template to ensure that proper arguments are passed, and the return value is treated correctly.
- 6. Each argument variable must be declared independently inside the parentheses. Float avg (int x, int y); // correct float avg (int x, y) ; // illegal ■ In a function declaration, the names of the arguments are dummy variables and therefore they are optional.
- 7. Call by Value Function call passes arguments by value. The called function creates a new set of variables and copies the values of arguments into them. The function does not have access to the actual variables in the calling program and can only work on the copies of values.
- 8. Call by Reference When we pass arguments by reference, the formal arguments in the called function become aliases to the actual arguments in the calling function. This means that when the function is working with its own arguments, it is actually working on theoriginal data.
- 9. Advantages of Functions Easier to Code Easier to Modify Easier to Maintain Reusability Less Programming Time Easier to Understand
- 10. Importance of Function A program may need to repeat the same piece of code at various places. It may be required to perform certain task repeatedly. • The program may become very large if functions are not used. The real reason for using function is to divide program into different parts
- 11. Function Overloading ■Can enables several function ■ Of same name ■ Of different sets of parameters (at least as far as their types are concerned) ■ Used to create several functions of the same name that perform similar tasks but on different data types
