Two-dimensional arrays

1. Defining a two-dimensional array

Int [,]myarray =new int[ Several one-dimensional arrays, number of arrays ];

An array can have more than one dimension. For example, the following declaration creates a two-dimensional array of four rows and two columns (which can be understood as 4 1 -dimensional arrays, with 2 elements in the array ):

Int [,] myarray=new int[4,2];

Int [,] myarray=new int[4,2] {{1,2},{3,4},{5,6},{7,8}};

The value is

Int i= myarray[0,0]

The output result I is:1

Int i=myarray[0,1]

The output result I is:2

Multidimensional arrays

An array can have more than one dimension. For example:

Int[,,] myArray = new int [2,4,2]

{{1,2},{3,4},{5,6},{7,8}}

{{9,10},{11,12},{13,14},{15,16}};

Enter class size, create an array based on the number of people

Storage language, math, English score

Ask for the average score for everyone

Console.Write (" Please enter class number:");

int a = Int. Parse (Console.ReadLine ());

double[,] Fenshu = new double[a, 3];

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

//{

Console.Write (" Please enter " + (i + 1) + " personal language score:");

Fenshu[i, 0] = double. Parse (Console.ReadLine ());

Console.Write (" Please enter " + (i + 1) + " personal math score:");

Fenshu[i, 1] = double. Parse (Console.ReadLine ());

Console.Write (" Please enter " + (i + 1) + " personal English score:");

Fenshu[i, 2] = double. Parse (Console.ReadLine ());

//}

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

//{

Double sum = fenshu[i, 0] + fenshu[i, 1] + fenshu[i, 2];

Console.WriteLine (" the" + (i+1) + " the average score of the individual is:" +SUM/3);

//}

Five candidate Monitor, a vote. (Enter 1-5 to indicate which person to support)

Finally check the number of votes to see which one wins

int[] Piao = new INT[20];

//console.writeline (" Span style= "font-family: Microsoft Jacob Black;" > Vote for squad leader, enter 1~5 which one is supported!

Console.WriteLine ("1: Zhang San 2: John Doe 3: Harry 4: Zhao Liu 5: Feng qi ");

for (int i = 0; i < 20;i++)

//{

Console.Write (" please " + (i+1) + " individual to vote:");

Piao[i] = Int. Parse (Console.ReadLine ());

//}

int fei = 0;

Int[] Shu = new int[] {0, 0, 0, 0, 0};

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

//{

Switch (Piao[i])

//    {

Case 1:

shu[0]++;

Break

Case 2:

shu[1]++;

Break

Case 3:

shu[2]++;

Break

Case 4:

shu[3]++;

Break

Case 5:

shu[4]++;

Break

Default

fei++;

Break

//    }

//}
