Introduction to C+ + Programming Concepts OVERVIEW OF PROGRAMMING BASICS, METHODOLOGIES, AND EXECUTION Processing a C++ Program  C++ programs need to be translated into machine language.  The translation process involves several steps.  Source Code (.cpp file)  Pre-processor Directives (#include)  Compiler: Translates to machine language  Linker: Combines object code with libraries  Loader: Loads executable into memory  Execution: Runs the program Source Code and Pre-processor Directives  Source Code: Written in.cpp files using a text editor. Example Filenames: Program.cpp, Sum.cpp, PLMUN.cpp  Pre-processor Directives: Begin with # (e.g., #include ). Compilation and Linking  Compiler:  Checks for syntax errors.  Translates source code into object code (machine language).  Linker:  Combines the object code with other necessary libraries.  Produces the executable code. Loading and Execution  Loader:  Loads the executable program into the main memory.  Execution:  The program is run and performs its tasks. Analysis-Coding-Execution Cycle Analyze the Implement the Maintain and problem and algorithm in a modify the design a programming program as solution. language. needed. Programming Methodologies Object- Structured Oriented Programmin Programmin g g Structured Programming Main Program  Definition:  Dividing a problem into smaller, manageable Module 1: Module 3: Module 2: subproblems.
