STEP 1: Start the program.
STEP 2: Declare the class as Prime with data members,
STEP 3: Consider the argument constructor Prime() with integer
STEP 4: To cal the function calculate() and do the following steps.
STEP 5: For i=2 to a/2 do
STEP 6: Check if a%i==0 then set k=0 and break.
STEP 7: Else set k value as 1.
STEP 8: Increment the value i as 1.
STEP 9: Check whether the k value is 1 or 0.
STEP 10:If it is 1 then display the value is a prime number.
STEP 11:Else display the value is not prime.
STEP 12:Stop the program.
Enter the number: 7
