maximum values

Find the maximum value of the following numbers 4,5,2,3

Solution:

       print*, 'enter the value of m,n,p,and P'

       read*, i,j,l,m

       k=max(i,j,l,m)

       print*, 'the maximum value is', k

       end

hints: here we put i= 4,j=5, l=2 and m=3 then we automatically find out the maximum value by the given formula.
