Some Things i didn’t know

• variable name - extern variable only significant to 6 letters in some cases

Can someone explain internal/external variable names?

• U, L at the end of integer
  • U can be added to represent unsigned number
  • L can be added to represent a Long number
  • ex. UL is for unsigned long
• storage allocator
  • Reusing freed memory
  • First fit vs Best fit - malloc uses first fit
  • brk vs mmap

brk / mmap
