Its depends upon the complier but generally int size is 2 bytes.

We can use modifier also for enhancing the size of int as given below:

There are two modifier for INT date type

1. unsigned                      (2 bytes)

2. long                             (4 bytes)

unsigned int x;   unsigned x;   (These both statements are same in C language and size is 2 bytes)

Becasue INT is by default data type in C language.

long int x;      long x;              (These both statements are same in C language and size is 4 bytes)

There are various ways using operators and expressions. The simplest way is always recommended with some physical world scenarios. 

As you asked for algorithm only.

Declare and initialize two variables first, second

Step 1 → Add first  and second and store to first

Step 2 → Subtract second from first and store to second

Step 3 → Subtract second from first and store to first

Swap completed.

Insight: 

Assuming variable having value first=10 and second=20

Now adding first with second and storing the result 10+20=30 in first.

Now subtracting the second which is still 10 from first and storing the result 30-10=20 in second

Here we achieved the initial swap

Then subtracting second which is 20 from first 30-20=10 and storing the result in first complene the final swap as now value inside variable first is 10 and second is 20.

Thank you
