Question 39

Easy

A database validation script needs to verify that a string stored in a variable named $serial_number\text{serial\_number}$ has the correct length. The number of characters in $serial_number\text{serial\_number}$ must be calculated and assigned to an integer variable named $num_chars\text{num\_chars}$ .

Which pseudo-code statement correctly performs this action?

$num_chars←LEN(serial_number)\text{num\_chars} \leftarrow \text{LEN}(\text{serial\_number})$

$serial_number←LEN(num_chars)\text{serial\_number} \leftarrow \text{LEN}(\text{num\_chars})$

$num_chars←LENGTH(serial_number)\text{num\_chars} \leftarrow \text{LENGTH}(\text{serial\_number})$

$num_chars←serial_number.length\text{num\_chars} \leftarrow \text{serial\_number.length}$
