Question

The statement z = 'expr 5 / 2' would store which of the following values in z?

1) 0
2) 1
3) 2
4) Cannot be determined

Answer 1

In a Unix-based system, the statement 'expr 5 / 2' assigns the result of the integer division of 5 by 2 to the variable z; thus, the value of z would be 2 as integer division truncates the decimal.

Step-by-step explanation:

The statement z = 'expr 5 / 2' appears to be from a scripting or programming context and is likely aimed at assigning a value to the variable z. In most Unix-based systems where expr is used for expression evaluation in shell scripts, this would evaluate the integer division of 5 by 2. Assuming that expr follows traditional integer division rules, the result would be 2, because integer division truncates the decimal part and only returns the integer quotient.
