3. Defination A compiler is a specialized program that translates high-level programming code written in a source language into machine code or an intermediate code that can be executed by a computer. The primary purpose of a compiler is to convert human-readable code into a format that a computer can understand and execute . Compiler /

4. How compiler works Semantic Analysis Syntax Analysis Lexical Analysis Source Code Intermediate Code Generation Code Optimization Code Generation and linking OUTPUT The syntax analysis phase checks the arrangement of tokens to ensure they form valid expressions and statements according to the language's grammar rules. The compiler checks the meaning of the code using semantic analysis .. For example, it checks data types, variable declarations, and function calls C ompiler's first phase is lexical analysis or scanning. The source code is broken down into individual tokens, such as keywords, identifiers, literals, and operators. This phase also removes comments and whitespace. . The compiler translates the optimized intermediate code into machine code If the program consists of multiple source files or modules, the compiler may link them together to create a single executable file . . Some compilers generate an intermediate code, which is a lower-level representation of the source code. This intermediate code is easier to optimize and can be platform-independent, allowing for portability The process begins with a programmer writing code in a high- level programming language such as C, C++, Java , or Python. This code is referred to as the source code The compiler performs various optimizations on the intermediate code to improve the efficiency of the generated machine code. Optimization techniques aim to reduce execution time, memory usage, or both . The final output of the compilation process is an executable file that can be run on the target computer. This file contains the translated machine code and any necessary information for the operating system to execute the program.

5. WHAT IS LINKER A linker is a software utility that combines one or more object files generated by a compiler into a single executable program or library. When a program is compiled, the source code is translated into machine code, resulting in one or more object files. These object files contain the machine code instructions, data, and other information needed to execute the program. ROLE OF LINKER

6. TYPES OF LINKER Contents Performance Contents Performance Performs linking at the time the program is loaded or during its execution. Dynamic linking allows multiple programs to share a single copy of a library, saving memory space. Dynamic linking can occur either when the program is loaded into memory (load-time linking) or when specific functions are called during execution (run-time linking ).. RUN TIME LINKER COMPILE TIME LINKER Performs linking at the time of compilation, combining all necessary object files into a single executable before the program runs. The resulting executable is self-contained and does not rely on external files during execution .

10. IDE USES It is a software application that provides comprehensive facilities to programmers for software development. An IDE typically includes a source code editor, a debugger, build automation tools, and other features that make the process of writing, testing, and debugging code more efficient and streamlined. The goal of an IDE is to provide a centralized environment that helps developers manage the entire software development life cycle, from writing code to testing and deployment

12. INTRODUCTION TO PF Programming is the process of designing and building an executable computer program to accomplish a specific task. It is a fundamental skill in today's technology-driven world, enabling individuals to communicate with computers and create software applications that solve problems, automate tasks, and facilitate various functionalities. . PROGRAMMING An algorithm is a step-by-step procedure or set of rules designed to perform a specific task or solve a particular problem. Algorithms are the building blocks of programming Programming languages are formal systems designed for instructing computers. They provide a way for humans to communicate instructions to machines. Examples include Python, Java, C++, and JavaScript. Syntax refers to the set of rules that dictate how programs written in a specific programming language should be structured. Proper syntax is crucial for the program to be understood and executed by the computer. Variables are containers for storing data values. They have names and can hold different types of information, such as numbers, text, or boolean values.

13. INTRODUCTION TO PF Control structures determine the flow of execution in a program. Common control structures include loops (repeating a set of instructions) and conditionals (executing specific instructions based on certain conditions). Functions are reusable blocks of code that perform a specific task. They help in organizing code, making it more modular and easier to maintain Programming languages support various data types, such as integers, floating-point numbers, strings, and more. Understanding data types is essential for managing and manipulating information within a program. Debugging is the process of identifying and fixing errors or bugs in a program. It involves analyzing the code, identifying the issue, and making corrections to ensure the program functions as intended . An IDE is a software application that provides comprehensive tools for writing, testing, and debugging code. It includes features like code editors, compilers, and debuggers to streamline the development process . Problem solving is fundamentally about solving problems. It requires breaking down complex issues into smaller, manageable tasks and then implementing solutions through code.

14. Basic structure of C language The basic structure of a C programming language program follows a specific format. A C program consists of a series of statements written within a set of curly braces. Here's a simple breakdown of the basic structure of a C program : # include < stdio.h > // Include necessary header files // Function prototype (if needed) // This informs the compiler about the existence of the function before it is defined. // It's not necessary for all functions. // Example: void my Function (); // The main function intmain () { // Declarations and statements go here // Example: Print "Hello, World!" to the console printf (" Hello, World!\n"); // Return statement return 0; }

15. Basic structure of C language Header files #include < stdio.h >: This line includes the standard input/output header file ( stdio.h ). It's necessary for using functions like print f and scan f . Other header files may be included for additional functionality . Function Prototype (Optional ): Function prototypes inform the compiler about the existence of a function before it is defined. It's not required for all functions, especially for the main function. If you define your own functions, you may include prototypes before the main function. // Example: // void myFunction (); Main Function : int main() { ... }: The main function is the entry point of a C program. Execution begins from here. The int before main indicates that the function returns an integer value. The curly braces {} enclose the body of the function Declarations and Statements : Declarations involve specifying the data types of variables and functions. Statements are instructions that the program executes. These can include variable declarations, assignments, conditionals, loops, and function calls . // Example: Variable declaration and assignment int age = 25;

16. Basic structure of C language printf Function : printf ("Hello, World!\n");: This statement prints "Hello, World!" to the console. The \n represents a newline character . Return Statement : return 0;: The return statement ends the main function. The 0 typically indicates a successful execution. Other values may be used to indicate errors
