"fflush()" flush any buffered output associated with filename, which is either a file opened for writing or a shell command for redirecting output to a pipe or coprocess.
Example: fflush(FilePointer); fflush(NULL); flushes all streams.
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;
}
