Arrays Intro

Which declaration creates an array that holds 5 ints?

• int[5] hand = new int[5];
• int[5] hand = new int[];
• int[] hand = new int[5];
• int hand = new int[5];

For the array:
double[] stats = new double[3];
What is the range of the index?

• 0 to 3
• 0 to 2
• 1 to 3
• 0 to 4

//Which array will win?
string status = "Win";  
if(player[3] == 4)          
  status = "lose";
if(player[1] == 3)            
  status = "lose";
if(player[2] == 2)            
  status = "lose";

• {0,1,2,3}
• {1,3,2,4}
• {3,2,1,4}
• {3,2,4,5}

//Which array will lose?
string status = "Win";
if(player[3] == 4)          
  status = "lose";
if(player[1] == 3)          
  status = "lose";
if(player[2] == 2)          
  status = "lose";

• {3,2,4,1}
• {1,2,3,4}
• {1,2,4,3}
• {3,4,1,2}

for(int i=0; i<10; i++)
           numbers[i] = 2 * i + 1;
// Which index of the array holds the value of 5?

• 1
• 2
• 3
• 4

for(int i=0;i<10;i++)

deck[2*i] = 5;

// Which statement will not print out 5?

• Console.WriteLine(deck[18]);

• Console.WriteLine(deck[0]);

• Console.WriteLine(deck[10]);

• Console.WriteLine(deck[20]);

for(int i = 1; i<=100; i++)

numbers[i-1] = i/10;

//At what index will the first 2 occur?

• 1

• 2

• 19

• 20

for(int i = 1; i<=100; i++)

numbers[i] = i%10;

//At what index will the first 5 occur?

• 4

• 5

• 49

• 50

//cArray is filled with "c"s.

for(int i=1;i<100;i++)

if(i<11)

cArray[i] = "d";

//At what index will cArray

have its first "c"?

• 0

• 1

• 11

• 12

Which is correct declaration of a 2D array with 5 rows and 2 columns?

• int [,] arrayTwoDee = new int [ 2 , 5 ];

• int [,] arrayTwoDee = new int [ 5 , 2 ];

• int [,] arrayTwoDee = new int [ 5 ; 2 ];

• int [,] arrayTwoDee = new int [ 2 . 5 ];
