Class 11 Computer Science Arrays (Part-II) Notes and Questions
Question 1 Define Multi-dimensional arrays.
Ans: Arrays which have more than one subscript or index value to access any element, is called multi-dimensional
array. These arrays can be 2 Dimensional or 3 Dimensional. For example:
Q:2 What are the different ways to define two dimensional arrays?
Ans: Two dimensional array is a multidimensional array. It is also called Matrix. It stores values in tabular form. It
means it store values in rows and columns as shown below. The different ways to define two-dimensional arrays are
Q:3 What is the importance of #define row 10?
Ans: #define is a pre-processor directive. It is used to define symbolic constants in the C program. In the given
example: #define row 10, a symbolic constant named row with value 10 is defined. During the execution of whole
program, value of row will be fixed, i.e. 10. We can not change the value of row during program execution. If we
change the value of row during design time, all occurrences of constant row will automatically changed to the new
value. We need not to change manually every occurrence of constant row in the program.
