That night, Arjun rewrote his weather station code. He replaced bulky struct arrays with bit fields. He used shift operators to read raw sensor data. He learned "circular buffers" from Chapter 10 to handle continuous data streams without memory leaks.
Arjun opened it. Chapter 7 was titled: "Bit Manipulation and Memory-Efficient Structures."
Two weeks later, the weather station booted in 0.3 seconds. It ran for 48 hours straight without a single crash. The professor called it "elegant, low-footprint C."
"I need to fix my C code," Arjun mumbled. "But I don't need another syntax guide. I need techniques ."
