Fluid flow when x,y,z are at 0 I'm creating a small video in which I have a glass and fluid as water to flow into the glass.

Now in my domain I do get a continuous fluid flow if I change the x,y,z direction coordinates under the domain but I get  fluid flow like water drops when x,y,z are 0.

The scene needs the flow of water directly over the glass but I don't get continuous smooth flow.

Any help would be appreciated here.

Regard,
The x,y,z values in the fluid domain settings define the effect of gravity on the simulation. Values of 0,0,0 mean the fluid is floating in space. A Z value of -9.81 is used to approximate earths gravity.

You have a couple of options for the object used as the starting point of the fluid, setting the type to fluid gives you a single "blob" of fluid with a total volume equal to the size of the mesh while a type of inflow will give you a constant flow of fluid coming in. The initial velocity here defines the direction the fluid first moves, a negative z value will have it fall straight down, while changing the x and y values can get it to flow diagonally into your cup.
