(Convert milliseconds to hours, minutes, and seconds) Write a function that converts milliseconds to hours, minutes, and seconds using the following header: def convertMillis(millis): The function returns a string as hours:minutes:seconds. For example, convertMillis(5500) returns the string 0:0:5, convertMillis(100000) returns the string 0:1:40, and convertMillis(555550000) returns the string 154:19:10. Write a test program that prompts the user to enter a value for milliseconds and displays a string in the format of hours:minutes:seconds. Sample Run Enter time in milliseconds: 555550000 154:19:10

I am writing the Python program. Let me know if you want the program in some other programming language.

def convertMillis(millis):  #function to convert milliseconds to hrs,mins,secs

   remaining = millis  # stores the value of millis to convert

   hrs = 3600000  # milliseconds in hour

   mins = 60000  # milliseconds in a minute

   secs = 1000  #milliseconds in a second

   hours =remaining / hrs  #value of millis input by user divided by 360000

   remaining %= hrs  #mod of remaining by 3600000

   minutes = remaining / mins  # the value of remaining divided by 60000

   remaining %= mins  #mod of remaining by 60000

   seconds = remaining / secs  

#the value left in remaining variable is divided by 1000

   remaining %= secs  #mod of remaining by 1000

   print ("%d:%d:%d" % (hours, minutes, seconds))

#displays hours mins and seconds with colons in between

def main():  #main function to get input from user and call convertMillis() to #convert the input to hours minutes and seconds

   millis=input("Enter time in milliseconds ")  #prompts user to enter time

   millis = int(millis)  #converts user input value to integer

   convertMillis(millis)   #calls function to convert input to hrs mins secs

main() #calls main() function

Explanation:

The program is well explained in the comments mentioned with each line of code. The program has two functions convertMillis(millis) which converts an input value in milliseconds to hours, minutes and seconds using the formula given in the program, and main() function that takes input value from user and calls convertMillis(millis) for the conversion of that input. The program along with its output is attached in screenshot.
