EPISODE 7: Typecasting in C: Safe, Unsafe & Dangerous

C gives you the power to reinterpret memory any way you want.
That same power can make you a systems engineer —
or crash your program silently.
In Episode 7 of Tech Strong with Shobhit, we break down Typecasting in C the right way — from a memory, CPU, and hardware perspective, not just syntax.
In this short but deep episode, you’ll understand:
What typecasting really does (interpretation vs conversion)
Implicit casting vs explicit casting
When casting is safe — and when it silently loses data
Why narrowing casts are dangerous
Why pointer casting is where real bugs live
How endianness, alignment, and CPU architecture matter
When pointer casting is actually valid (MMIO, hardware registers, firmware)
Why volatile is critical in embedded systems
We’ll also cover misaligned pointer access, undefined behavior, and the golden rules every C programmer must remember.
This episode is especially useful if you’re preparing for:
Embedded systems & firmware roles
System programming interviews
Low-level C / C++ development
OS, kernel, or driver work
