There are two types of arrays :
1)One Dimensional Array
2)Multi or Double Dimensional arrays
Programs for 1d array
1)Simple array program
class abc
{
static void Main()
{
string[] names=new string[5];
for(int i=0;i<5;i++)
{
System.Console.WriteLine("Enter name of People");
names[i]=System.Console.ReadLine();
}
for(int i=0;i<5;i++)
{
System.Console.WriteLine(names[i]);
}
}}
2)Reverse an array
class abc
{
static void Main()
{
int[] a={45,66,43,12,85};
for(int i=0;i
System.Console.WriteLine(a[i]);
}
System.Array.Reverse(a);
System.Console.WriteLine("reverse is");
for(int i=0;i
System.Console.WriteLine(a[i]);
}
}
}
Two dimensional arrays
1)Program for Populationa and sector
using System;
class abc
{
static void Main()
{
int[ , ] population = new int [5,2];
for(int i=0;i<5;i++)
{
Console.Write("Enter secttor no. ");
population[i,0]=Convert.ToInt32(Console.ReadLine());
Console.Write("Enter Population ");
population[i,1]=Convert.ToInt32(Console.ReadLine());
}
for(int i=0;i<5;i++)
{
Console.WriteLine("{0} population is {1}",population[i,0],population[i,1]);
}
}
}
2)Transpose of a matrix
class abc
{
static void Main()
{
int[ , ] matrix = new int[4,4];
int[ , ] matrix2 = new int[4,4];
for(int j=0;j<=3;j++)
{
for(int i=0;i<=3;i++)
{
System.Console.Write("Enter Element {0},{1} : ",j,i);
matrix[j,i]=System.Convert.ToInt32(System.Console.ReadLine());
}
}
for(int j=0;j<=3;j++)
{
for(int i=0;i<=3;i++)
{
System.Console.Write(matrix[j,i]);
}
System.Console.WriteLine("");
}
System.Console.WriteLine("its transpose is");
for(int j=0;j<=3;j++)
{
for(int i=0;i<=3;i++)
{
matrix2[i,j]=matrix[j,i];
}
}
for(int j=0;j<=3;j++)
{
for(int i=0;i<=3;i++)
{
matrix[i,j]=matrix2[i,j];
}
}
for(int j=0;j<=3;j++)
{
for(int i=0;i<=3;i++)
{
System.Console.Write(matrix[j,i]);
}
System.Console.WriteLine("");
}
}
}
