An introduction to software assertions and Design by Contract (DBC) methodology in the context of embedded programming. Covers what assertions are, how the C standard assert facility works (with GCC demos), and the critical distinction between programming errors (bugs) and exceptional conditions. Explains why defensive programming hides bugs, while assertions act like fuses in electrical circuits — detecting failures loudly rather than masking them. DBC, pioneered by Bertrand Meyer, frames assertions as contractual obligations between software components validated automatically at runtime. Part 2 will cover applying assertions and DBC in embedded C/C++.
