Do not shift an expression by a negative number of bits or by greater than or equal to the number of bits that exist in the operand 138 INT35-C. Use correct integer precisions 143 INT36-C. Converting a pointer to integer or integer to pointer 145 Chapter 5: Floating Point (FLP) 151 FLP30-C. Do not use floating-point variables as loop counters 152 FLP32-C. Prevent or detect domain and range errors in math functions 154 FLP34-C. Ensure that floating-point conversions are within range of the new type 163 FLP36-C. Preserve precision when converting integral values to floating-point type 166 Chapter 6: Arrays (ARR) 169 ARR30-C. Do not form or use out-of-bounds pointers or array subscripts 170 ARR32-C. Ensure size arguments for variable length arrays are in a valid range 180 ARR36-C. Do not subtract or compare two pointers that do not refer to the same array 182 ARR37-C. Do not add or subtract an integer to a pointer to a non-array object 184 ARR38-C. Guarantee that library functions do not form invalid pointers 187 ARR39-C. Do not add or subtract a scaled integer to a pointer 196 Chapter 7: Characters and Strings (STR) 201 STR30-C. Do not attempt to modify string literals 202 STR31-C. Guarantee that storage for strings has sufficient space for character data and the null terminator 205 STR32-C. Do not pass a non-null-terminated character sequence to a library function that expects a string 218 STR34-C. Cast characters to unsigned char before converting to larger integer sizes 223 STR37-C. Arguments to character handling functions must be representable as an unsigned char 227 STR38-C. Do not confuse narrow and wide character strings and functions 229 Chapter 8: Memory Management (MEM) 233 MEM30-C. Do not access freed memory 234 MEM31-C.
