Question 1

What function is used to copy a string in C?

A

strcpy()

B

strcat()

C

memcpy()

D

strncpy()

Correct Answer: A

Explanation:

strcpy() is used to copy a string in C.

Question 2

When working with specialized programming considerations in C, what is a common method used to optimize code for performance?

A

Compiler optimization

B

Loop unrolling

C

Function inlining

D

Parallel processing

Correct Answer: C

Explanation:

Function inlining is a common method used to optimize code for performance by replacing a function call with the body of the function itself at the call site.

Question 3

C

To initialize the argument list pointer to the first variable parameter.

D

To retrieve the next argument from the argument list.

Correct Answer: B

Explanation:

The va_end macro is used to end the processing of the variable argument list.

Question 5

When dealing with specialized programming considerations in C, what is the role of compiler flags?

A

Compiler flags control optimization levels
