Question

What is the difference between the expressions val = 1234567 and val = 1.234567 * 10 ** 6?

In the first expression val is of type int, in the second val is of type float. Numerical values are different.
The value of the variable val in the first expression is different from the value of the variable val in the second expression.
In the first expression val is of type int, in the second val is of type float. Numerical value is the same.
No difference.
The two values are not equal

What are the values of the variables a, b, c and d after the following statements have been executed?

a=1

b=2

c=a+b

a = b

a = c

d=a+c

a will be 1, b will be 2, c 3 and d 6.
a will be 2, b will be 2, c 3 and d 4.
a will be 3, b will be 2, c 3 and d 6.
a will be 1, b will be 2, c 3 and d 4.
