SWAPPING OF VALUES (Using 3rd Variable)

SWAPPING OF VALUES

(Using 3^rd Variable)

AIM:

            To write a Shell Program to swap two values using 3^rd variable.

ALGORITHM:

Step 1: Read the Values of ‘a’ and ‘b’

Step 2: Swap the values of ‘a’ to the third variable ‘temp’    

Step 3: Swap the value of ‘b’ to ‘a’ and ‘b’ to ‘temp’

Step 4: Print the swapped values of ‘a’ and ‘b’

Step 5: Stop.

SHELL PROGRAM:

echo "Enter Two Numbers"

read a b

temp=$a

a=$b

b=$temp

echo $a $b

SAMPLE OUTPUT:

Enter Two Numbers

12 10

10 12

RESULT:

            Thus the program to swap two values using 3^rd variable was executed and the output was verified.
