There is two number in two variables. We have to swap the position of the numbers. For example, the
 |
Swap |
variable
x holding integer value
5 and another variable
y holding the integer value
10. Now we have to swap the position of those two numbers.
We can use another
temporary variable to store the value of
x.
 |
Swap fig: 01 |
Now we have a backup copy of the value of
x into the
temp variable.
So we can now give the value of
y to
x.
 |
Swap fig: 02 |
Yes, we have done half of our job!!
x is now holding the value of
y. Now time to assign the value of
x into
y. Remember, we have saved the value of
x into the
temp variable in
figure 01. So now put the temp value to
y.
 |
Swap fig: 03 |
Oh yes. Now look..! We have successfully swapped the value of
x to y and the value of
y to x.
Now it's time to check what we understand. Write a program to swap two number:
