Study Notes
Introduction to C++ Programming
- Facilitates a well-structured approach to program design
- Processes information and displays results
- The text provides examples of displaying messages, obtaining user input, performing calculations, and making decisions
First C++ Program: Printing a Line of Text
- A simple program that displays a line of text
- Illustrates key features of the C++ language
Comments in C++
- Comments are used to explain code to other programmers and make the program more readable
- Ignored by the compiler
- Single-line comments start with //
- Multi-line comments start with /* and end with */
Control Statements
- Basic problem-solving techniques are important for writing programs
- The
ifandif...elsestatements allow for choosing between different actions - The
whilestatement allows for repeated code execution - There are two types of repetition: counter-controlled and sentinel-controlled
- Increment, decrement, and assignment operators are used to manipulate variables
Introduction
- Understanding the problem thoroughly before writing code is crucial for successful problem solving
- Carefully planning your approach to solve the problem helps write effective code
- Being familiar with available programming building blocks simplifies program development
- Following good programming principles leads to well-structured and maintainable code
Control Structures
- Programs execute statements sequentially by default
- Transfer of control refers to changing the execution flow from a sequential order
- Structured programming eliminates the use of
gotostatements - Structured programming is characterized by the use of three main control structures:
- Sequence structure
- Selection structures
- Repetition structures
Control Structures (Cont.)
- Only three control structures are needed for structured programming:
- Sequence structure (default sequential execution)
- Selection structures (
if,if...else,switch) - Repetition structures (
while,do...while,for)
- The three control structures (sequence, selection, repetition) are considered single-entry/single-exit statements
- These control statements can be combined in two ways:
- Control statement stacking (connecting the exit point of one to the entry point of the next)
- Control statement nesting (placing one control statement inside another)
C++ Keywords
- C++ keywords are reserved words that have specific meanings within the language
- They cannot be used as identifiers (variable names, function names, etc.)
- There are keywords common to both C and C++
- There are keywords specific to C++ only
if Selection Statement
-
ifstatements are used to execute code conditionally - An
ifstatement checks a condition and executes the code within its block only if the condition is true - The
ifstatement is also known as the single-selection statement - If the condition is false, the code within the
ifstatement is skipped
