Consider the following code segment:

a = input("Enter the value of a:")
b = input("Enter the value of b:")
print(a + b)

If the user runs the program and enters 11 for a and 9 for b then what will the above code display?

Consider the following code segment:

a = input()
b = int(input())
c = a + b 
print(c)

When the program is run, the user first enters 10 and then 5, it gives an error. Find the error, its reason and correct it

Consider the following program. It is supposed to compute the hypotenuse of a right triangle after the user enters the lengths of the other two sides.

a = float(input("Enter the length of the first side:"))
b = float(input("Enter the length of the second side:"))
h = sqrt(a * a + b * b)
print("The length of the hypotenuse is", h)

After adding import math to the code given above, what other change(s) are required in the code to make it fully work ?

Consider the following program. It is supposed to compute the hypotenuse of a right triangle after the user enters the lengths of the other two sides.

a = float(input("Enter the length of the first side:"))
b = float(input("Enter the length of the second side:"))
h = sqrt(a * a + b * b)
print("The length of the hypotenuse is", h)

When this program is run, the following output is generated (note that input entered by the user is shown in bold):

Enter the length of the first side: 3
Enter the length of the second side: 4
Traceback (most recent call last):
h = sqrt(a * a + b * b)
NameError: name 'sqrt' is not defined

Why is this error occurring? How would you resolve it ?
