1. Chapter 7: Array

3. Array: Introduction
Many application require the processing of multiple data items that have common characteristics
Array is the best option of variable to store such data which shares common name
An array is a collection of data items, all of the same type, accessed using a common name.
An array is a datastructure containing number of data value, all of which have the same datatype
Common name is followed one or more subscripts

4. Array: Declaration
Similar to normal variable but size should be defined
Syntax:
data_type array_name[size]
Example:
int roll[50];

5. Array: initialization

6. Getting values from user in array
Can be done using loop
Eg:

8. Example 1: Program to enter n element in array and display their sum

9. Example 2: Program to enter array and display in reverse order
Program to find maximum and minimum number in array
Program search a element in array

10. Example 3: Program to convert lowercase to uppercase

11. Best Appreciation Ever Made

12. Multi-dimentional Array
Syntax:
data_type array_name[size1][size2]….[]
Can be effectively used using n-nested loop

13. Multi-dimentional array example
Program to add, subtract two matric
Program to Transpose matrix
Program to find lower and upper triangular matrix
Program to replace all no diagonal element to zero
Program to find sum of all element in matrix
Program to find sum of diagonal element
