C/C++获取整型随机数

#include "time.h"
#include "windows.h"

int random(int max_range = 1)
{
	if (max_range == 1) return rand() << 16 | rand();
	return (rand() << 16 | rand()) % max_range;
}

int _tmain(int argc, _TCHAR* argv[])
{
	srand((unsigned int)time(NULL));	//Just use once at startup  for random()
	printf("Randoms: %08X  %08X  %08X \n", random(), random(), random(1000));
	return 0;
}
