"thermistor does not name a type" error message

hello i'm having difficulty trying to use the THERMISTOR library. THERMISTOR - Arduino Libraries
i'm sure it's something simple and am hoping you can give me a hint.

i downloaded the .zip file, opened it and copied all the files into a subdirectoy named "THERMISTOR-1.0.2" in the ...\ProgramFiles\Arduino\libraries directory.

here's the code in my programme:

#include <thermistor.h>

thermistor temp(0);

void setup() {
  Serial.begin(9600);
  

}

void loop() {
  int sicaklik = temp.getTemp();
  Serial.print("Sicaklik");
  Serial.print(sicaklik);
  Serialprintln(" C");
  delay(1000);
 

}

Have you tried the example that came with the library?

C++ is case sensitive; thermistor and THERMISTOR are NOT the same thing.

What is this line supposed to do?

thermistor temp(0);

"thermistor" is not declared anyplace. temp is not declared anyplace.
