Answer:
b. Associativity
Explanation:
Associativity specifies the order in which operators are processed vis a vis operands/values in an expression. For example: Consider the expression: a + b + c. Here a + b is evaluated first before adding the result with c as the '+' operator is left associative. The default associativity can also be overridden by the use of parentheses. For example a + (b + c) . In this case b+c will be evaluated first.
Answer:
c) 2^32 times as many values can be represented.
Explanation:
It's funny, this problem comes from a real-life situation, except it wasn't really foreseen :-) And we will encounter a similar problem in less than 20 years.
The difference in terms of storage capacity from 32-bit integers and 64-bits integers is huge.
A 32-bit integer can store (signed) numbers up to 2,147,483,647. (so over 2 BILLIONS)
A 64-bit integer can store (signed) numbers up to 9,223,372,036,854,775,807 (9 BILLIONS of BILLONS)
Answer:
That it
Explanation:
There have been mass extinctions during the Cenozoic as there were during the Mesozoic and Paleozoic, but not as many animals and plants have disappeared. Finally, humanity appeared during the last two million years.The human lineage only diverged from our most recent common ancestor about 5 million years ago; less than half of 1% of that time, and modern Homo sapiens is only between 200,000 and 50,000 years old, depending on your definition.
