Try this: (Compiled but untested.)

const int numReadings = 100;
const int analogInPin = A0;  
int inputReading [numReadings];

void setup() 
{
  Serial.begin(115200); 
}

void loop()
{
  for (int i = 0; i < numReadings; i++) {
    inputReading [i]= analogRead(analogInPin); // roughly 9kHz sampling
  }
  
  for (int i = 0; i < numReadings; i++) {    
    float voltage = ((inputReading[i]/1023.0)*5.0);                             
    Serial.println(voltage);  
  }
}
