Answer:
From -2147483647 to 2147483648.
Step-by-step explanation:
A 32 bit integer has 2^32 = 4294967296 possible values. A signed integer has positive and negative values as well as the zero.
Of these values (2^32)/2 will be positive, (2^32)/2 - 1 will be negative and one will be the zero.
Therefore the range is from -(2^32)/2 + 1 to (2^32)/2.
This can also be expressed as from -2147483647 to 2147483648.
