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

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];
