Here I discuss about array. How it works and its application.

2. What Is Array ??
 Collection Of same type of data.
 Data Type ( Int, float, double, char).
 Saves data in a sequence.
 Examples:
 1. Employees Info of an organization.
 2. Score of students of a class.
 3. Table of daily rainfall data.
 4. Temperature record of hours.

3.  Three Types Of Array
 One Dimensional Array(1-D)
 Two Dimensional Array(2-D)
 Multi Dimensional Array(A[s1][s2[s3][s4]…)

4.  Initialization:
 Type Array_name [Size];
 Type Array_name [Size] = {list of Values};
 Example:
 int A[10];
 int A[5] ={50,60,70,80,90};
 User Define:
 int A[n]; [Size of Array declare by User.]

5. Two Dimensional Array(2-D)
 Initialization:
 Type Array_name[row_size][column_size];
 Type Array_name[row_size][column_size]={{s1},{s2},{s3}};
 Here s1,s2,s3 refers to sets of number.
 Example:
 int A[3][3] ;
 int A[3][3] = {{10,20,45},{42,79,81},{89,9,36}};
 User Define:
 int A[r][n];
 Value of {r,n} given by user .

6.  Initialization:
 Type Array_name[s1][s2][s3]…..[sm];
Example:
int survey [3][5][3];
float table [5][4][5][3];
Pros & Cons:
Two dimensional array often
consider as multi dimensional array.
Multi dimensional array is derived
from basic C Language.
Multi Dimensional array
Example

7.  One Dimensional Array(1-D):
 Loops runs from 0 to n-1 th index.
 Sorting might involve if data was ask in sorting mode.
How 1-D array insertion Works:
For 0 to n-1
{input value;(Using scanf)}
int A[5]

8. Insertion In An Array
 Two Dimensional Array(2 - D):
 Loops runs
for 0 to row – 1
{for 0 to column – 1
input value;(scanf) }
How It works:
int A[3][4];
Step 1 Step 2 Step 3

9.  One Dimensional Array(1-D):
 User given input.
 Search for data
 Runs in the loops looking for the given input.
2 Condition: Found or Not found
Found condition:
Example: search: 4 (Found if available).
 Not Found (Print Not Found)
ORIGIN (Array) After Deletion

10. Two Dimensional Array(2D)
 User Given Input(search: 12)
 Process:
Runs inside the loops looking for element.
Condition:
If found delete the input value and replace by ‘0’
Else print not found.
Example: Before After
