time_t t; Which one of the following statements will properly initialize the variable t with the current time from the sample above
-
t = ctime();
-
time( &t );
-
t = localtime();
-
t = clock();
time(&t) correctly initializes t with the current time. The time() function takes a pointer to a time_t variable and stores the current time there. Option B is correct. ctime() converts a time value to a string, localtime() converts to local time structure, and clock() returns processor time used - none of these initialize t directly.
To properly initialize the variable t with the current time, you can use the time() function from the ctime library.
Option A) t = ctime(); - This option is incorrect because the ctime() function returns a string representation of the current time, not the actual time value.
Option B) time( &t ); - This option is correct because it calls the time() function and passes the address of t as an argument, allowing time() to store the current time value in t.
Option C) t = localtime(); - This option is incorrect because the localtime() function converts a time value into a broken-down time structure, not the current time.
Option D) t = clock(); - This option is incorrect because the clock() function measures the processor time, not the current time.
The correct answer is Option B.
