Well done, you have learned to check if the number is Even or Odd!
You can view the code of the above program in ‘Python’ by selecting ‘Python’ as an Editor.
What Exactly are Functions?
A unction is a loc o code hich is made up o a set o steps that result in a single specific action.
The programmer ill gi e a simple name to this specific unction as gi ing a simple name to a
function, increases the chances that the set of steps can be easily reused again and again in the
program.
Function Parameters
Function parameters are variables local to the function, taken as input to do a task when the function
is called and are part o the definition. Arguments are the alues that are passed on to the unction
received by the function as a parameter. A function can have more than one parameter, and in this
case order in which arguments are passed matters.
So Function parameters are the names listed in the unction definition and Function arguments are
the real values passed to (and received by) the function.
Example:
To calculate the volume (V) of a cuboid, you need three variables length (L), breadth (B) and height
(H). The formula to calculate the volume of a cuboid is V = L * B * H.
