Merging codes togther

Hello guys please help me for contact two codes to gather please

first code of
temperature :thermometer:
And
glucose.
And
Screen also


:thermometer: Code of Temperature :point_down:

#include <Adafruit_MLX90614.h>
Adafruit_MLX90614 mlx = Adafruit_MLX90614();
void setup() { Serial.begin(9600);

Serial.println("Adafruit MLX90614 test");

if (!mlx.begin()) {
Serial.println("Error connecting to MLX sensor. Check wiring.");
while (1);
};
}
void loop() {
Serial.print("C = "); Serial.print(mlx.readObjectTempC()); Serial.println("C");
delay(500);}


Code of glucose :point_down:

// include the library code:

// initialize the library with the numbers of the interface pins
Adafruit_LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

void setup()
{

   while (millis() < 3000)

{

if(digitalRead(13==HIGH))

{

//Read the Alcohol max value

for(i1=0;i1<90;i1++)
{

Serial.print(i1);
Serial.print(" : ");
Serial.println(tab1[i1]);

  if(tab1[i1]>max_1)
                    {

                     indice_max1 = i1;
                    }
}

  Serial.print("max1=");

}

Serial.print("max2=");

Serial.print(indice_max2);
Serial.print(" : ");
Serial.println(max_2);

}

}

MAXG1=max_1;
MAXG2=max_2;

//Alcohol
X1=(MAXG1*180)/1023;
Serial.print("X1=");
Serial.print(X1);
Serial.println("ppm");

// Propane

Serial.print(X2);
Serial.println("ppm");

Y=aX1+bX2+c;
Serial.print("Y=");
Serial.print(Y);
delay(5000);
lcd.print("Glycemia : ");
lcd.setCursor(0, 1);
lcd.print(Y);
lcd.print(" mg/dl");
}

void loop()
{
// set the cursor to column 0, line 1
// (note: line 1 is the second row, since counting begins with 0):
// print the number of seconds since reset:
}


And here code of screen TPT

Code of screen :point_down::point_down:

if (ID == 0xD3D3) ID = 0x9481; //force ID if write-only display
tft.begin(ID);
tft.setRotation(1);

}

void loop(void)

}

void showmsgXY(int x, int y, int sz, const GFXfont *f, const char *msg)
{
int16_t x1, y1;
uint16_t wid, ht;
// tft.drawFastHLine(0, y, tft.width(), WHITE);

Read the forum guidelines to see how to properly post code and some hints on how to get the most from this forum.
Use the IDE autoformat tool (ctrl-t or Tools, Auto format) before posting code in code tags.

Please include the entire error message. It is easy to do. There is a button (lower right of the IDE window) called "copy error message". Copy the error and paste into a post in code tags. Paraphrasing the error message leaves out important information.

Combine codes.
Merging codes.

Please edit your post to add code tags.

In order to merge program codes, you have to first go through each program and make sure that you understand what each line of the program does.
