Hi Upendra, Here my_matrix is an array and you are trying to get first element length and this loop will run number of times. i.e you first element of an array is 'ABC' then my_matrix[0].lenth retutns 3 and loop will run 3 times. Put debugger and check values, you will be able to see values.

Hi, In your program my_matrix[0].Length refer to string length means it will calculate length of string of first word or number which is stored in array. my_matrix.length refer to array length ang calculate number of element in array. For Array.length and string.length refer following document: https://www.geeksforgeeks.org/how-to-find-the-length-of-an-array-in-c-sharp/ https://www.geeksforgeeks.org/c-sharp-string-properties/
