Prime number is a number that has only two factors i.e. the number itself and 1. For example, 2 , 3 , 5, 7 , 11 , 13 , 17 , 19 , 23 , 29….
Here we are given a number, and we need to find whether the given number is prime or not.
Input : A number Output : “The number is prime ” OR “The number is not prime” based on the number.
Example −
Input : 23 Output : The number is prime
ALGORITHM
Step 1 − Loop from 2 to n/2, i as loop variable
Step 2 − if number is divisible, print “The number is not prime” and flag = 1;
Step 3 − if flag != 1, then print “The number is prime”.
Step 4 − Exit.
PROGRAM
number=53 i=2 flag=0 while test $i -le `expr $number / 2` do if test `expr $number % $i` -eq 0 then flag=1 fi i=`expr $i + 1` done if test $flag -eq 1 then echo "The number is Not Prime" else echo "The number is Prime" Fi
OUTPUT
The number is Prime
