C passing array to function

Passing Array to Function in C
Array Definition :
Array is collection of elements of similar data types .
Passing array to function :
Array can be passed to function by two ways :

1. Pass Entire array
2. Pass Array element by element

Let us discuss both of them one by one :
1 . Pass Entire array

• Here entire array can be passed as a argument to function .
• Function gets complete access to the original array .
• While passing entire array Address of first element is passed to function , any changes made inside function , directly affects the Original value .
• Function Passing method : “Pass by Address“

• Here individual elements are passed to function as argument.
• Duplicate carbon copy of Original variable is passed to function .
• So any changes made inside function does not affects the original value.
• Function doesn’t get complete access to the original array element.
• Function passing method is “Pass by Value“
