i want to write a program using "for" loop, that will generate the following output.

value of a is 0, value of b is 2

value of a is 0, value of b is 4

value of a is 0, value of b is 6

value of a is 1, value of b is 2

value of a is 1, value of b is 4

value of a is 1, value of b is 6

value of a is 2, value of b is 2

value of a is 2, value of b is 4

value of a is 2, value of b is 6
