      A user needed help with the following as it was returning errors:

      #include <SmartInventor.h>
      int a = 0;
      int b = 1 / a;
      void setup() {
        // put your setup code here, to run once:
        Serial.begin(57600);
        SmartInventor.DCMotorUse();
        int left = anologRead(19);
      }
      
      void loop() {
        // put your main code here, to run repeatedly:
      
        while (a < 10) {
          a = a + 1;
          b = a * a + a;
          Serial.println(a);
          Serial.println(b); Serial.println("test");
          delay(1000);
          if (Serial.available() > 0) {
            Serial.println((char)Serial.read());
          }
        }; 
        
        for (int c = 0; c < 10; c++) {
          Serial.println(c);
          delay(1000);
          SmartInventor.DCMotor(M1, CCW, 100);
        }
      
        while (left < 500) {
          Serial.println(left);
          SmartInventor.DCMotor(M1, CCW, 100);
        }
        SmartInventor.DCMotor(M1, CW, 1000);
        Serial.println("end");
        SmartInventor.DCMotor(M1, STOP, 10);
        delay(5000);
      }

              delay(5000);
            }
            

            Please note that you are only able to have "1" void setup, and 1 void loop method.

              The solution to this error is as follows:

              The problem regarding this error, is actually that the code declares a variable "int left". This cannot be used as the library <SmartInventor.h> uses this variable already. As a result the user has to rename the variable so that the code can function. something like left_ir_sensor or l_sensor will suffice/not interfere with the library that the user has added.
