how to give variable inputs in coding

suppose i want to give an input x= 5 in the range varying from 0 to 10 and another input y=4.1 in the same range. my output is z.

 so how can i define the input and output using 'function'. 
for eg:
     function z= data(x,y)
the x and y should be given externally or is not included in the coding

thanks for helping in advance

Ambika,

I'm not sure I follow your question. Are you asking how to limit the range of the inputs or how to define a function that accepts x and y as two inputs?

If you want to limit the range, you will have to do it yourself inside the function to check that both x and y are within the range, and if not, throw an error.

If you just wanted to define the function, what you have should work. Although I would name the function something more intuitive (and relevant to what the function does, for instance addition) other than "data".

Cheers, -Venn
