Memory
Storage Classes in C
The 4 variable attributes (storage, default value, scope, lifetime) across auto, register, static, and extern storage classes.
Explore Lecture 6 →
L7
Type System
Type Casting & Type Conversion
Implicit type promotion hierarchy, explicit type casting (type)expr syntax, integer demotion, truncation, and data loss risks.

I/O Streams
Input & Output Statements
Formatted I/O (printf, scanf), format specifiers, width/precision, memory address & operator, and the Input Buffer Trap simulator.
Explore Lecture 8 →
L9
Branching
Conditional & Branch Statements
Simple if, two-way if-else, nested if-else with dangling else traps, and multi-way if-else ladder grade calculators.
Explore Lecture 9 →
L10
Selection
Switch-Case & Selection Control
Multi-way selection based on integral expressions, case label rules, fallthrough mechanics, and switch vs if-else comparison.
Explore Lecture 10 →
L11
Jumps
Jump Statements (break, continue, goto)
Deep-dive into break for early search exits, continue for iteration filtering, and goto with statement labels for nested loop breakouts.
