I wanted to know if I could convert the following if else statement into a switch statement in c++. If I can could someone please tell me how, as currently I am getting errors the way I have written it.

This is the if else statement i am trying to convert into a switch statement.

if ( t>=10 && t <=18 ) {
        blue=0; green=1; red=1;
        xb_led=0; xg_led=1; xr_led=1;

    } else if ((t >18 && t<=22)||(t>22 && t<=25)) {
        green=0; blue=1; red=1;
        xg_led=0; xb_led=1; xr_led=1;
    } else {
        red=0; green=1; blue=1;
        xr_led=0; xg_led=1; xb_led=1;
    } 

This is what I have converted it to but I get an error.

switch(t) {

        case t >=10 && t<=18:
        blue=0; green=1; red=1;
        xb_led=0; xg_led=1; xr_led=1;
        break;

        case t >18 && t<=22|| t>22 && t<=25:
        green=0; blue=1; red=1;
        xg_led=0; xb_led=1; xr_led=1;
        break;

        case t >25:
        red=0; green=1; blue=1;
        xr_led=0; xg_led=1; xb_led=1;
        break;             

    }
