The document shows the values of two variables, a and b, both before and after attempting to swap their values using a function. In the first example, the swap fails as the values remain the same at 100 and 200. In the second example, the swap succeeds as the values are now reversed at 200 and 100. The document notes that the swap function uses pointers to the variables' addresses to directly modify the original variable values.

7. Max value is : 200

12. Before swap, value of a :100
Before swap, value of b :200
After swap, value of a :100
After swap, value of b :200

15. Before swap, value of a :100
Before swap, value of b :200
After swap, value of a :200
After swap, value of b :100

19. Before swap, value of a :100
Before swap, value of b :200
After swap, value of a :200
After swap, value of b :100
NOTE:
Calling a function to swap the
values.
&a indicates pointer to a ie.
address of variable a and
&b indicates pointer to b ie.
address of variable b.

21. Total value is :300
Total value is :120
