How do I get random swapping in arrays?

[psychoticbear]

I'm trying to figure out how to randomly swap different elements in an array of structures, but I'm stuck. Wondering if anyone could help me out.

This is what I have so far:

void shuffle()
{
   Music temp;
   unsigned int currentTime = (unsigned)time(0);

   srand(currentTime);
   
   for (int i = 0; i < NUM_SONGS; i++)
   {
      songs[i] = temp;
	  i = (rand() % NUM_SONGS) + 1;
	  temp = songs[i];
	  
   }
}

Any help is appreciated!

If you don't want to use library function, just look at the implementation example.
