The code you provided has multiple errors.

The first error is that the type Robot is unknown. To fix this, you need to define the struct Robot before using it:

struct Robot {
    int blood;
    int x;
    int y;
};

The second error is that you are trying to access the blood member of robot without using the dot operator on a structure or union. To fix this, you need to use the dot operator:

robot.blood = 100;

The third error is similar, you are trying to access the x member of robot without using the dot operator:

robot.x = 0;

After making these changes, your code should compile without errors
