Tabular Data Display from DHT and ATM

Your code formatting makes your code hard to follow, and even the IDE's auto format tool struggled, so I did a little manual formatting

#include "DHT.h"
#include <Adafruit_Sensor.h>
#include <LiquidCrystal.h>

#define DHTTYPE DHT11
#define DHTPIN 5

DHT dht(DHTPIN, DHTTYPE);

float celsius = 0;
float fahrenheit = 0;
float h = 0;
float t = 0;
float f = 0;
float hif = 0;
float hic = 0;

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

void findTemps_ATM() 
{
  float voltage = 0;
  float sensor = 0;
  sensor = analogRead(0);
  voltage = (sensor + 100) * 5000 / 1024;
  voltage = voltage - 500;
  celsius = voltage / 10;
  fahrenheit = (1.8 * celsius) + 32;
}

void findTemps_DHT() 
{
  h = dht.readHumidity();
  t = dht.readTemperature();
  f = dht.readTemperature(true);
  if (isnan(h) || isnan(t) || isnan(f)) {
    Serial.println(F("Failed to read from DHT sensor!"));
    return;
  }
  hif = dht.computeHeatIndex(f, h);
  hic = dht.computeHeatIndex(t, h, false);
}

void displayTemps() 
{
  Serial.println("\nTemperature\tCelsisus\tFahrenheit");
  Serial.println("------------------------------------------");
  for (int i = 0; i < 5; i++) {
    Serial.print("Current Temp:\t");
    Serial.print(celsius, 2);
    Serial.print("\t\t");
    Serial.println(fahrenheit, 2);
    //Serial.println(analogRead(0)); //for debugging and calibration
    delay(5000);
  } 
  delay(1000);
  Serial.println("\nHumidity\tTemp:\tCelsisus\tFahrenheit\tIndex
                 Temp:\tCelsisus\tFahrenheit");
  Serial.println("-------------------------------------------------------------------------
                 -------------------------");
  for (int i = 0; i < 5; i++) {
    Serial.print(h);
    Serial.print("\t\t\t");
    Serial.print(t);
    Serial.print("\t\t");
    Serial.print(f);
    Serial.print("\t\t\t\t");
    Serial.print(hic);
    Serial.print("\t\t");
    Serial.print(hif);
    Serial.println("\t");
    delay(5000);
  } 
  delay(1000);
}

void loop() 
{
  findTemps_ATM();
  findTemps_DHT();
  displayTemps();
  delay(1000);
}

I can't see what leads you to think

I don' t think I'll ever understand this programming construct.
