  • Question
  • What will the function randomize() do in Turbo C under DOS?


  • Options
  • A. returns a random number.
  • B. returns a random number generator in the specified range.
  • C. returns a random number generator with a random value based on time.
  • D. return a random number with a given seed value.

  • Correct Answer
  • returns a random number generator with a random value based on time. 

    Explanation
    The randomize() function initializes the random number generator with a random value based on time. You can try the sample program given below in Turbo-C, it may not work as expected in other compilers.

    /* Prints a random number in the range 0 to 99 */
    
    #include <stdlib.h>
    #include <stdio.h>
    #include <time.h>
    
    int main(void)
    {
        randomize();
        printf("Random number in the 0-99 range: %d\n", random (100));
        return 0;
    }
