Which of the following statements are correct about the C#.NET code snippet given below?
int[ , ] intMyArr = {{7, 1, 3}, {2, 9, 6}};- intMyArr represents rectangular array of 2 rows and 3 columns.
- intMyArr.GetUpperBound(1) will yield 2.
- intMyArr.Length will yield 24.
- intMyArr represents 1-D array of 5 integers.
- intMyArr.GetUpperBound(0) will yield 2.

Option:1 Correct because the dimensions are 2 rows and 3 columns.
Options:2 Correct because the upper bound in the array means the first element in an array of the mentioned index.
As intMyArry. GetUpperBound (0) means intMyArray[1][0].
Options:2 Correct because the upper bound in the array means the first element in an array of the mentioned index.
As intMyArry. GetUpperBound (0) means intMyArray[1][0].

Hi,
Please share the answer.
If int[, ,]a={3,2,3}.
Then what is the length of a?

int[ , ] intMyArr = this gives us idea of getting a two dimensional matrix.
So ans 1 is right.
So ans 1 is right.

By examining syntax of this array it is clear that - this is a 2-D array with 2 rows and 3 columns.
GetUpperBound(0) returns the upper bound for the indexes of the first dimension of the Array, and GetUpperBound(1) returns the upper bound of the last dimension of the Array.
GetUpperBound(0) returns the upper bound for the indexes of the first dimension of the Array, and GetUpperBound(1) returns the upper bound of the last dimension of the Array.

How intMyArr.GetUpperBound(1) will yield 2. the output of this statement should be 7 how come it is 2. It is represents rectangular array of 2 rows and 3 columns.

@Natasha, It will yield 2 because there are two rows in this two dimensional array. Index starts from 0 so intMyArr.GetUpperBound(0) will yield upper bound 1 and intMyArr.GetUpperBound(1) will yield upper bound 2.

Yes first one is the right answer. Because array declared as a second array.

int[ , ] z = {{7, 1, 3}, {2, 9, 6}};
Console.WriteLine("Rank (Dimensions)1 UP {0} LOW {1} Rank 2 UP {2} LOW {3}",z.GetUpperBound(0),z.GetLowerBound(0),z.GetUpperBound(1),z.GetLowerBound(1));
GetUpperBound => Returns index of the last element of the specified dimension in the array.
GetLowerBound => Returns index of the first element of the specified dimension in the array.
Output:
Rank (Dimensions)1 UP 1 LOW 0 Rank 2 UP 2 LOW 0.
Console.WriteLine("Rank (Dimensions)1 UP {0} LOW {1} Rank 2 UP {2} LOW {3}",z.GetUpperBound(0),z.GetLowerBound(0),z.GetUpperBound(1),z.GetLowerBound(1));
GetUpperBound => Returns index of the last element of the specified dimension in the array.
GetLowerBound => Returns index of the first element of the specified dimension in the array.
Output:
Rank (Dimensions)1 UP 1 LOW 0 Rank 2 UP 2 LOW 0.
