Which of the following statements uses the computer’s clock to initialize the random number generator? A. srand(time); B. srand(time(NULL)); C. time(srand); D. time(srand(NULL));

srand(time);
srand(time(NULL));
time(srand);
time(srand(NULL));

The correct answer is A. srand(time);

The srand() function initializes the random number generator with a seed value. The time() function returns the current time as a number of seconds since the Unix epoch (January 1, 1970, at UTC). Therefore, the statement srand(time); uses the computer’s clock to initialize the random number generator.

The statement srand(time(NULL)); also uses the computer’s clock to initialize the random number generator, but it uses the current time in the local time

zone instead of UTC.

The statements time(srand) and time(srand(NULL)) are both incorrect. The time()

function returns a number of seconds, but the srand() function expects a pointer to an integer. Therefore, these statements will cause a compiler error.
