Q2.Program to find solution of quadratic equation.

import cmath
a=float(input("enter a"))
b=float(input("enter b"))
c=float(input("enter c"))
d=(b**2)-(4*a*c)
sol1=(-b-cmath.sqrt(d))/(2*a)
sol2=(-b+cmath.sqrt(d))/(2*a)
print(sol1,sol2)

Output
>>>

    n=n//10
    
if (num%s==0):
    print(str(num)+ "is harshad number")
else:
    print(str(num)+" is not harshad number")
    
Output
>>>
