Answer:

a) TRUE.

Explanation:

The statement is true.We can declare a variable but not initialize it there we can initialize it afterwards when we want to use.On declaring the variable type it tells the compiler to reserve the memory according to the size required for the data type.When we initialize the memory is allocated to that variable.

How many bit strings of length 12 contain the substring 111000?
ELEN [110]

Answer:

448 strings

Explanation:

Each bit string can be filled by two ways either 0 or 1. If the bit strings of length contain the substring '111000' we therefore need a substring of length 6.

The selection of bits starts from the 1st bit to 7th bit enclosing the substring 111000 and ensuring that the length 6 are all filled. So, there will be  7 ways to contain this substring.

The total ways to contain this substring = 7*2^6 =448

Therefore 448 strings of length 12 contain the substring '111000'.
