Answer:
This is in python
Explanation:
Alter my code if you need anything changed. (You may need to create a new function to add a day to February if necessary)
months = [31,28,31,30,31,30,31,31,30,31,30,31]
monthNames = ['january','february','march','april','may','june',
'july','august','september','october','november','december']
array = []
def test(y,m,d): #Does not account for leap-year. Make a new function that adds a day to february and call it before this one
if m.lower() not in monthNames or y < 1 or d > 31:
if m.lower() == "april" or m.lower() == "june" or m.lower() == "september" or m.lower() == "november" and d > 30:
return None
elif m.lower() == "february" and d > months[1]:
return None
return None
num = monthNames.index(m.lower()) #m should be the inputted month
months[num] = d
date = months[num]
for n in range(num):
array.append(months[n])
tempTotal = sum(array)
return tempTotal + date
x = int(input("Enter year: "))
y = input("Enter month: ")
z = int(input("Enter day: "))
print(f"{y.capitalize()} {z} is day {test(x,y,z)} in {x}")
