Finding and getting data from a static table (Vectorized Data Query)

To give you more information my table is like this :

I rather hope that's not really so, because it makes no sense at all. If all your "Z" and "Y" values are the same, what's the point of having two of them?

As-is, you don't seem to have Y as a function of X and Z, or Z as a function of X and Y, like you said you did. You have X and V as a function of an index number that goes from 1 to n.

OK here is:

1) You select y or z from menu of your program.This will be manual selection.
2) You are getting x values from a sensor to cpu
3) You are matching this x value with y or z according to your first sellection in step 1

For example :

x y z
1 11 23
2 10 22
3 9 26
4 7 20
. . .
. . .
192 34 24

1) I selected y so i will use y values for my next matching operations.
2) I got x value (lets say 4) from a sensor automaticaly
3) then i should match x and y for 4. So result will be 7.

The problem is values are not mathematical they are random so i could not write formulas. I need matching form table as fast as i can.

That is a one-dimensional lookup, and it seems like all x values between 1 and 192 are represented. So instant lookup...

struct {
    unsigned y,z;
} my_table[] = {
    {11,23},
    {10,22},
    ...
};

my_y_result = my_table[x-1].y;
my_z_result = my_table[x-1].z;

You may optionally define y = 0 and z = 1 and have a two-dimensional array:

unsigned my_array[][2] = {
    {11,23},
    {10,22},
    ...
};

my_y_result = my_table[x-1][0];
my_z_result = my_table[x-1][1];
