A jagged array is an array whose elements are arrays. It is recommended over a multidimensional array because the arrays that make up the elements
can be of different sizes, which avoids wasting memory space.
Noncompliant code example
int [,] myArray = // Noncompliant
{
{1,2,3,4},
{5,6,7,0},
{8,0,0,0},
{9,0,0,0}
};
// ...
myArray[1,1] = 0;
Compliant solution
int[][] myArray =
{
new int[] {1,2,3,4},
new int[] {5,6,7},
new int[] {8},
new int[] {9}
};
// ...
myArray[1][1] = 0;
