int n=12345;How many bytes in a text file will store the value of n ?Select one:a.7b.5c.4d.6e.2

Break Down the Problem

1. Identify the data type of n and its representation in a text file.
2. Understand how many characters are needed to represent the integer n in text.

Relevant Concepts

1. The integer n = 12345 consists of digits.
2. Each digit takes up one byte when represented in ASCII encoding.

Analysis and Detail

1. The integer n has 5 digits: 1, 2, 3, 4, and 5.
2. In a text file, each digit is typically stored as a single character, which corresponds to one byte.

Verify and Summarize

• Since 12345 has 5 digits and each digit takes 1 byte, the total number of bytes required is: $\text{Total Bytes} = \text{Number of Digits} = 5$

Final Answer

The correct answer is b. 5.
