Question
Select the correct answer
In C, what is the result of the expression sizeof(float)
?
Options
- 284
- Compiler-dependent
Solution
Break Down the Problem
- Identify the expression to analyze:
sizeof(float)
. - Understand what
sizeof
does in C: it returns the size (in bytes) of a data type.
Relevant Concepts
- In C, the
sizeof
operator yields the size of a data type or object in bytes. - The size of
float
is typically defined by the C standard, but it can be platform-dependent.
Analysis and Detail
- The size of
float
is usually 4 bytes on most systems (e.g., on 32-bit and 64-bit architectures). - Hence, evaluating
sizeof(float)
will commonly return4
.
Verify and Summarize
- The options provided are
284
andCompiler-dependent
. - Based on common compilers and the C standard, the size of
float
is always 4 bytes, not284
and it's not strictly compiler-dependent as it will generally follow the standard.
Final Answer
The result of the expression sizeof(float)
is 4.
