Study Notes
Operators
- Perform operations on variables and values.
- Categories include:
- Arithmetic Operators: + (addition), - (subtraction), * (multiplication), / (division).
- Comparison Operators: == (equal to), != (not equal to), > (greater than), < (less than).
- Logical Operators: && (logical AND), || (logical OR), ! (logical NOT).
Data Types
-
Primitive Data Types: Basic types provided by programming languages to hold simple values.
- int: Stores integer values (e.g., 10, -20).
- float: Stores floating-point numbers (e.g., 3.14, -2.5).
- char: Stores a single character (e.g., 'A', 'b').
- bool: Stores Boolean values (true/false).
-
Reference Data Types: More complex types that refer to objects, storing addresses of actual data.
- Arrays: Collections of elements of the same type (e.g., int arr = {1, 2, 3, 4, 5}).
- Strings: Sequences of characters (e.g., string name = "John" in C++).
- Classes: Custom data types created by programmers (e.g., class Car { public: string model; int year; }).
Variables
- Defined as named storage locations in memory that can hold values that may change.
- Act like labeled boxes for storing data.
- Example usage:
int age = 25;(age holds the value 25)float height = 5.9;(height holds the value 5.9)char grade = 'A';(grade holds the character 'A').
Basic C++ Code Example
- Demonstrates the use of primitive data types:
- Variables defined for integer, float, character, and boolean types.
- Example of printing values using
cout.
Analogies for Understanding
- Data types are compared to containers for different kinds of data (e.g., boxes for toys, books, or liquids), emphasizing the need for proper data storage types in programming.
Refined Definitions
- Data Types: Specify the type of data a variable can hold (e.g., integers, floats, characters).
- Variables: Named storage in memory that can be modified during program execution.
Software Development Lifecycle (SDLC)
- Involves steps such as Planning, Software Design, Building Software, Testing Software, and Deploying Software.
- Each step involves specific actions that ensure effective software development and deployment.
Challenges in Software Testing
- Various challenges may arise, including lack of user feedback, incomplete requirements, or software bugs.
- Address challenges by engaging users early, defining clear requirements, and conducting comprehensive testing protocols.
Requirement Gathering for Projects
- Emphasize the importance of understanding stakeholder needs through direct communication and iterative feedback.
- Methods may include interviews, surveys, or focus groups to ensure clarity in gathered requirements.
