b) Rewrite this code segment using a for loop and a switch case statement instead of the while loop and if statements. Note: The functions are NOT one from our demo lab code. (5 pts) unsigned char trial = 0, tP_history [100]; while (trial < 100) { } tP = alphaTouchPad (); // returns letter A-E for touch pad tP_history [trial] = tP; if (tP == 'A') led_on(0); else if (tP == 'B') led_on (1); else if (tP == 'C') led_on(2); else if (tP == 'D') led_on (3); else if (tP == 'E') led_on(4); trial++;
