In the line that reads “println ( float ( lines [currentPoint] ) ) ;”, which of the following is the best description of what “float” does?

Converts lines[currentPoint] to an integer.

Converts an element of lines to a number with a fractional part.

Selects a random line to print

Converts the variable currentPoint to a number with a fractional part

Converts lines[currentPoint] to an integer.

Converts an element of lines to a number with a fractional part.

Selects a random line to print

Converts the variable currentPoint to a number with a fractional part

Ans)Converts an element of lines to a number with a fractional part.

Reason:

Here according to the question lines is an array and currentPoint is an index pointing to the elements of an lines array.

so lines[currentPoint] is the element in the lines array and we are type casting that element value into float type number.

So "Converts an element of lines to a number with a fractional part." is right
