Help with sending the serial out values to an LCD in code

I have been working on a depth measurement system using a pressure sensor and an arduino, i have got a code but am wondering how i could send the serial.print values in the code to an LCD screen? i have attached a file with the code i have got, any help would be amazing.

float temperature_c, temperature_f;
double pressure_abs, pressure_relative, altitude_delta, pressure_baseline;


double base_altitude = 1655.0; // Altitude of SparkFun's HQ in Boulder, CO. in (m)

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

    sensor.begin();

  Serial.println(temperature_c);

double altitude(double P, double P0)

Which LCD display do you have ?
Can you write text to the LCD ?

The principle is simple. Create an instance of the LCD, then in loop() position the LCD cursor, print a label then print the corresponding value as you do with Serial.print(). Perhaps do not print during each pass through loop() but at a greater interval or when a value changes.

You will need to include an LCD library, create an instance of LCD and set the instance up. The examples in the library should show how to do that for your particular LCD and interface. Once set up, use the library print and write methods to send data to the LCD. Here is the library that I use LCD library

I don't have an LCD screen yet will be purchasing in the next few days, just a basic one. In the serial monitor the Temp,pressure(abs),pressure relative and pressure change values are constantly being refreshed, all i was aiming to do was to get those 4 values refreshing on the LCD screen in real time, i've only recently starting using arduino coding so am still learning. Thankyou for reply's, all help is needed..

Look at the LCDs with I2C backpacks. They only require 2 pins to interface (versus 6 to 10 for parallel interface).
