    C

  • Description

    The conditions for a given point to be lies on the x-axis and y-axis or on the origin are:
    a) For origin; x is equal to 0 and y is equal to 0.
    b) For y-axis; x is equal to 0 and y is not equal to 0.
    c) For x-axis; x is not equal to 0 and y is equal to 0.
    Write an algorithm to find out if given point (x, y) lies on the x-axis, y-axis or on the origin.
