Select the correct answerWhat is the range of values that can be stored in an unsigned char variable in C?Options0 to 2550 to 127-128 to 127-255 to 255

Break Down the Problem

1. We need to determine the range of values for an unsigned char variable in the C programming language.
2. The options given are:
   • 0 to 255
   • 0 to 127
   • -128 to 127
   • -255 to 255

Relevant Concepts

1. An unsigned char in C is a data type that can store only non-negative values.

2. The typical size of an unsigned char is 1 byte (8 bits).

3. The maximum value of an unsigned type is calculated as $2^n - 1$, where $n$ is the number of bits.

4. For an unsigned char, with $n = 8$, the maximum value would be:

   $2^8 - 1 = 255$

Analysis and Detail

1. The minimum value for an unsigned char is 0 (since it cannot be negative).
2. Therefore, the range of values that can be stored in an unsigned char is from 0 up to 255.

Verify and Summarize

• The calculated range is confirmed to be from 0 to 255.
• Reviewing the provided options, the correct answer aligns with our conclusion.

Final Answer

The range of values that can be stored in an unsigned char variable in C is 0 to 255.
