5. (5 marks) Write code for a function with the following prototype: /Addition that saturates to TMin or TMax int saturating_add(int x, int y); Instead of overflowing the way normal twos-complement addition does, satu- rating addition returns INT_MAX when there would be positive overflow, and INT_MIN when there would be negative overflow. Saturating arithmetic is com- monly used in programs that perform digital signal processing. Your function should follow the bit-level integer coding rules above
