Deconstruct #include <iostream>, int main(), std::cout, and return 0.

Master the sacred semicolon rule, whitespace rules, and single/multi-line developer comments.

Master memory boxes: int, double, float, char, bool, and std::string.

Master writing output and reading interactive keyboard input from users.

Perform math calculations, division quirks, modulo remainders, and ++/-- shortcuts.

Master conditional decision-making using comparison operators (==, !=, >, <, >=, <=).

Combine multiple boolean conditions with AND, OR, and NOT.

Cleanly handle menu choices, day codes, and keyboard inputs with case, break, and default.

Repeat blocks of code as long as a boolean condition remains true.

Master 3-part iteration: initialization, condition check, and increment step.

Terminate loops early with break, and skip unwanted iterations with continue.

Break complex programs into clean functions with parameters, return types, and prototypes.

Understand how the & reference symbol modifies original variables and saves memory.

Store sequences of elements in fixed-size contiguous memory blocks with zero-based indexing.

Master modern resizable arrays with push_back(), size(), and range-based for loops.

Master std::string methods: length, substring, find, concatenation, and getline.

Demystify C++ memory addresses, pointer variables, and the dereference operator.

Bundle related variables into custom data models using struct and dot notation (.).

Unite variables, control flow, functions, structs, and vectors into a complete banking engine.
