Do not rely on side effects in operands to sizeof, _Alignof, or _Generic 102<br>EXP45-C. Do not perform assignments in selection statements 105</p> <p><b>Chapter 4: Integers (INT) 111<br></b>INT30-C. Ensure that unsigned integer operations do not wrap 112<br>INT31-C. Ensure that integer conversions do not result in lost or misinterpreted data 118<br>INT32-C.

Guarantee that storage for strings has sufficient space for character data and the null terminator 205<br>STR32-C. Do not pass a non-null-terminated character sequence to a library function that expects a string 218<br>STR34-C. Cast characters to unsigned char before converting to larger integer sizes 223<br>STR37-C. Arguments to character handling functions must be representable as an unsigned char 227<br>STR38-C. Do not confuse narrow and wide character strings and functions 229</p> <p><b>Chapter 8: Memory Management (MEM) 233<br></b>MEM30-C. Do not access freed memory 234<br>MEM31-C. Free dynamically allocated memory when no longer needed 239<br>MEM33-C. Allocate and copy structures containing a flexible array member dynamically 241<br>MEM34-C.
