**AIM:**

To write a shell program for the following:

(i) multiplication table

(ii) square of 1-10 numbers.

**ALGORITHM:**

**Multiplication table:**

· Get the numbers to be displayed for multiplication and limit of the multiplication table.

· Check using while loop.

· Calculate the result.

· Increment the variable and repeat.

· Display the value an terminate the program.

interchanging two numbers using without temporary variable:

· Using for loop read number from 1-10.

· Calculate the square of 1’s number and assign it to value.

· Repeat the step for all number one by one.

· Display the result.

· Terminate the program.

PROGRAM SOURCE CODE

(i) multiplication table:

echo ”enter a”

read n

echo “multiple”

for I in 1 2 3 4 5 6 7 8 9 10

do

m= `expr $n\*$i `

echo “$i x $n = $m”

done

(ii) square of 1-10 numbers:

for I in 1 2 3 4 5 6 7 8 9 10

do

t= `expr $i\* $i `

echo “square of $i is $t”

done

**CONCLUSION:**

Thus the shell program for displaying the multiplication table of any number and the square of 1-10 numbers are written and executed successfully.
