static void Main(string[] args)
{
int[ ][ ] jaggedArr = new int[ ][ ]
{
new int[ ] {1,8,2,7,9},
new int[ ] {2,4,6},
new int[ ] {33,42}
};
int x = jaggedArr[2][1];
Console.WriteLine(x);
}
}
}

Answer 1

Because of [2][1]

Here row wise index is 2 and column wise index is 1. So will check in third array where on 1st index value is 42

Answer 2

Imagine an array which contains 3 other arrays.

The outer array has indices. And all inner arrays has indeces.

jaggedArr[0][x] means the first inner array -> 1,8,2,7,9
jaggedArr[0][0] = 1
jaggedArr[0][1] = 8
jaggedArr[0][2] = 2
jaggedArr[0][3] = 7
jaggedArr[0][4] = 9

jaggedArr[2][x] means this array: 33,42
inside this array the value of index 1 is 42
-> jaggedArr[2][1] = 42
