Const int inf 0x3f3f3f
WebIn practice, constant initialization is performed at compile time, and pre-calculated object representations are stored as part of the program image (e.g. in the .data section). If a variable is both const and constant initialized, its object representation may be stored in a read-only section of the program image (e.g. the .rodata section) WebUse 0x3f3f3f to represent infinity.
