Compiler diagnostics: “If a function contains two return statements one after another, the compiler will generate warnings.” Decide Yes or No (consider typical conforming compilers).

Introduction / Context:This question targets understanding of unreachable code detection. Two return statements in succession make the second statement unreachable. Most compilers warn about unreachable code when warnings are enabled, which is a helpful diagnostic for dead or mistaken logic.

Given Data / Assumptions:

• Code pattern: return expr1; return expr2; without intervening control transfer.
• Typical toolchains with warnings enabled (e.g., -Wall -Wextra in GCC/Clang or corresponding MSVC warnings).

Concept / Approach:The first return transfers control to the caller, so any statements immediately following cannot execute. Compilers perform control-flow analysis and issue a warning for unreachable statements. While the C standard does not require a diagnostic here, practical compilers commonly warn.

Step-by-Step Solution:Identify the code pattern with back-to-back returns.Recognize that the second return cannot run.Conclude a “Yes” answer: expect a warning about unreachable code.

Verification / Alternative check:Compile a test function with two consecutive returns under common compilers; you will typically see “warning: unreachable code” or equivalent when warnings are enabled.

Why Other Options Are Wrong:No / linker-based answers: linkers do not analyze per-statement reachability; compilers do. Optimization/debug settings are not required for the diagnostic, though settings can influence whether the warning is emitted.

Common Pitfalls:Confusing “required by standard” with “common compiler behavior”; omitting warnings flags and missing useful diagnostics.

Final Answer:Yes
