Reading 2 voltages simultaneously with Arduino

I've got the code from the Adruino-Examples-Basic-ReadAnalogueVoltage file, but I want to read 2 voltages (A0 and A1) at the same time and display them. I just want to test if my Mega is faulty on the analog but don't know coding, and don't really want to spend 3 months learning it for a 3 min test. Any simple hacks.

// the setup routine runs once when you press reset:
void setup() {
// initialize serial communication at 9600 bits per second:
Serial.begin(9600);
}

// the loop routine runs over and over again forever:
void loop() {
// read the input on analog pin 0:
int sensorValue = analogRead(A0);
// Convert the analog reading (which goes from 0 - 1023) to a voltage (0 - 5V):
float voltage = sensorValue * (5.0 / 1023.0);
// print out the value you read:
Serial.println(voltage);
}

Thanks
