Question

What statement is executed the most × (just the piece of code that is executed the most)? Without recompiling, run the profiled program again and run gcov again. The statistics should now represent both runs together. The counts are set back to zero only when you recompile.

a) While loop
b) If statement
c) For loop
d) Switch statement

Answer 1

Without specific gcov output data, a general answer would be that loop statements, like while loops and for loops, are executed more often than if or switch statements due to their repetitive nature.

Step-by-step explanation:

The question seems to be related to the use of the gcov tool, which is a test coverage program used for monitoring the execution of a program and identifying the most frequently executed parts of the code. The specific piece of code that is executed the most is not explicitly stated in the context, as this would depend on the actual program code that is being profiled.

Without recompiling the program, running it again, and using gcov afterward, would accumulate the coverage statistics across multiple program executions. If you are asked about which statement is executed the most, typically one would look at the gcov output to determine this. However, the loop statements such as while loops and for loops are generally executed more frequently than if statements or switch statements, because they are designed to repeat code blocks multiple times.
