# Multidimensional Arrays

The multidimensional array is also known as rectangular arrays in C++. It can be two dimensional or three dimensional. The data is stored in tabular form (row ∗ column) which is also known as matrix.

## C++ Multidimensional Array Example

Let's see a simple example of multidimensional array in C++ which declares, initializes and traverse two dimensional arrays.

snippet
```#include <iostream>
using namespace std;
int main()
{
int test[3][3];  //declaration of 2D array
test[0][0]=5;  //initialization
test[0][1]=10;
test[1][1]=15;
test[1][2]=20;
test[2][0]=30;
test[2][2]=10;
//traversal
for(int i = 0; i < 3; ++i)
{
for(int j = 0; j < 3; ++j)
{
cout<< test[i][j]<<" ";
}
cout<<"\n"; //new line at each row
}
return 0;
}```

Output:

Output
5 10 0 0 15 20 30 0 10

## C++ Multidimensional Array Example: Declaration and initialization at same time

Let's see a simple example of multidimensional array which initializes array at the time of declaration.

snippet
```#include <iostream>
using namespace std;
int main()
{
int test[3][3] =
{
{2, 5, 5},
{4, 0, 3},
{9, 1, 8}  };  //declaration and initialization
//traversal
for(int i = 0; i < 3; ++i)
{
for(int j = 0; j < 3; ++j)
{
cout<< test[i][j]<<" ";
}
cout<<"\n"; //new line at each row
}
return 0;
}```

Output:"

Output
2 5 5 4 0 3 9 1 8
