Go Lab [3] – type ,Pointer ,zero value, array, slice ,variadic function, map

Temp in The City

1. Type Declaration:
   • Define a new type Temperature which is an alias for float64.
   • Create a variable roomTemp of type Temperature and initialize it to a suitable value.
2. Pointer:
   • Write a function increaseTemp that takes a pointer to Temperature and increases its value by a given amount.
3. Zero Value:
   • Declare a variable defaultTemp of type Temperature without initializing it. Print its value to demonstrate the zero value of a float64.
4. Array:
   • Create an array weekTemps of type Temperature with a length of 7, representing temperatures for a week.
5. Slice:
   • Create a slice weekendTemps from the weekTemps array that includes only temperatures for the weekend.
6. Variadic Function:
   • Write a function averageTemp that calculates the average temperature. It should take a variadic Temperature slice as an argument.
7. Map:
   • Create a map tempByCity where keys are city names (as string) and values are Temperature.
   • Add at least three city-temperature pairs to the map, and then iterate over the map to print each city and its corresponding temperature.
8. Putting it All Together:
   • Use the increaseTemp function to increase the temperature of a city in tempByCity.
   • Update the weekTemps array based on new data and recalculate the average using averageTemp.
