Study Notes

Program Execution Analysis

Program iterates through a list, comparing each letter to a target letter.
Increments position index to move through the list.
Reads the current letter at each position.
Checks if the current letter is empty. If empty, increments listTop and updates current position.
Updates target letter from listTop.
Continues comparison, moving to the next position if the current letter does not match the target letter.

Error Types in C++

Syntax Error: Occurs when the compiler detects a violation of the programming language's rules (e.g., missing semicolons, typos).
- Results in an error message displayed by the compiler.
- Similar to grammatical errors in writing.
Warning Message: Indicates potential issues in the code, but does not prevent compilation.
- Example: Declaring a variable that is never used.
Run-time Error: An error that occurs during program execution, not during compilation.
Human Error: Errors arising from typos or misunderstanding of the logic, resulting in an incorrect output even with correct syntax.
- Example: Mistaking a subtraction for multiplication operator.

Data Types in C++

int: Represents whole numbers (positive, negative, and zero).
- Different sizes:
  - short int (2 bytes)
  - int (4 bytes)
  - long int (8 bytes)
float / double: Represents floating-point numbers (numbers with decimal points).

Memory Allocation and Initialization

Variables only allocate memory space when declared. They are not automatically initialized to a specific value (e.g. 0).
Garbage values may be present in the allocated space if the previous program didn't initialize it to 0.
It's crucial to initialize variables to prevent unexpected behavior.

Identifiers

Names given to variables and other items within a C++ program.
Must follow specific naming conventions (e.g., variable names use camelCase).

Assignment Statements

Used to assign values to variables.
Assignment always occurs from right to left.
