Arjun was a second-year computer science student, and he had a problem. His team’s semester project—a handheld digital weather station—was due in two weeks. The hardware was ready: sensors, an LCD screen, a microcontroller. But the firmware was a disaster.
Arjun held up a dog-eared copy of Padma Reddy's book. "This isn't a book you read from start to finish," he said. "It's a toolkit. You keep it on your desk. When you face a problem—memory is tight, code is slow, pointers are misbehaving—you flip to the technique you need. It's the difference between knowing C and thinking in C."
The senior smiled and pulled out a thick, worn paperback with a faded blue cover: C Programming Techniques by Padma Reddy.
