Question about Arrays.

  
char Array[10];
int num;
for( int i = 0; i < 10; i++ )
   Array[i] = 0;
for( i = 0; i < 10; i++ )
{
   num = rand()%9;
   while( Array[num] != 0 )
      num = rand()%9;
   Array[num] = i+1;
}
  

  
int Array[10];

// Initialize to the desired set of numbers

for(int i=0;i<10;++i)
	Array[i]=i+1;

// Shuffle

for(int i=9;i>0;--i){
	int j=rand()%(i+1);
	int temp=Array[i];
	Array[i]=Array[j];
	Array[j]=temp;
}
