• Word

• String

• Nibble

• Byte

How many characters can a processor handle in a 16-bit word size at a time?

• 4 characters

• 2 characters

• 8 characters

• 16 characters

What is the primary difference between a word and a string in computing?

• A word is numeric, and a string is a series of characters.

• A word is fixed-length binary data, and a string is variable-length characters.

• A word is for text, while a string is for numbers.

• They are essentially the same.

In a 32-bit system, how many bits are in a word?

• 16 bits

• 8 bits

• 64 bits

• 32 bits

A character array is terminated by which special character in C strings?

• '\n'

• '\t'

• '\0'

• ' '

Which of the following best describes the term 'word' in a computing context?

• The basic unit of communication between systems

• A fixed-size unit of data used by the processor

• A combination of strings

• The smallest part of a string

The strncpy function differs from strcpy because:

• It copies a string completely without specifying length.

• It appends characters to a string.

• It allows the number of characters to be copied to be specified.

• It deletes characters from a string.

What does strncat do?

• Concatenates entire strings.

• Concatenates up to N characters of a source string to the destination.

• Deletes characters from a string.

• Copies characters to a string.

If you want to compare only the first 5 characters of two strings, you use:

• strcmp

• strcpy

• strlen

• strncmp

The function strlen calculates:

• The number of words in a string

• The total memory size of the string including the null terminator

• The number of characters in a string excluding the null terminator

• The number of special characters in a string
