C++ Types Of Array

The Various types of Array are given below:-

(1) One Dimensional Array
(2) Two Dimensional Array
(3) Three Dimensional array
(4) Character Array of String

(1) One Dimensional Array

The one dimensional array or single dimensional array is the simplest type of array that contains only one row for storing data.

array_name[size]; 

int a[];

#include
void main()
{         
int i,a[5]={20,30,40,50,60};        
for(i=0;i<5;i++)
{      
cout<<"No Is " << [i];    
}      
} 

output:
No Is 20
No Is 30
No Is 40
No Is 50
No Is 60

(2) Two Dimensional Array

The Two Dimensional array is used for representing the elements of the array in the form of the rows and columns and these are used for representing the matrix.A Two Dimensional Array uses the two subscripts for declaring the elements of the Array

array_name[size1][size2]; 

int a[][];

#include
void main()
{
   int i,j,a[2][3];
   for(i=0;i<2;i++) 
   {
      for(j=0;j<3;j++) 
	  {
         cout<<"Enter value for a[%d][%d]:" << i << j;
         cin>>a[i][j];
      }
   }
   cout<<"Two Dimensional array elements:";
   for(i=0;i<2;i++) 
   {
      for(j=0;j<3;j++) 
	  {
         cout<< a[i][j];
         if(j==2)
		 {
            cout<<"\n";
         }
      }
   }
}

output:Two Dimensional array elements:
1 2 3
4 5 6

(3) Three Dimensional array or Multidimensional array

A Three dimensional Array is used when we wants to make the two or more tables of the Matrix Elements for Declaring the Array Elements.

array_name[size1][size2][size3]; 

int a[][][];

#include
void main()
{
int i, j, k;
int a[3][3][3]=
{
{{1,1,1},{1,1,1},{1,1,1}},
{{2,2,2},{2,2,2},{2,2,2}},
{{3,3,3},{3,3,3},{3,3,3}}
};
cout<<"Array Elements\n\n";
for(i=0;i<3;i++)
{
    for(j=0;j<3;j++)
    {
        for(k=0;k<3;k++)
        {
        cout<< a[i][j][k];
        }
        cout<<"\n";
    }
     cout<<"\n";
}
}

output:Two Dimensional array elements:
1 1 1
1 1 1
1 1 1

2 2 2
2 2 2
2 2 2

3 3 3
3 3 3
3 3 3
