C++ Substring for Integers or setting max width for Integers?

[VaultV3]

Hi , I'm currently working on a project for my c++ course in which a user enters 3 different numbers for a date. The program then will ask them which of the following formats would they like their output. 

1. 10/7/14

2. October 7, 2014

3. 7-Oct-2014

 

I can handle everything but the first option. If the user entered 2014 for his/her year, how would i make sure the program only displays 14 instead of 2014?

You grab the whole line, and separate each into 3 strings through substringing such that

string day = "10", month = "7" and year = "2014"

for year, simply check for size of the string.

if(year.size() == 4)

   substring one more time to extract the last 2 digits

you can then use stringstream or stoi to convert and check day/month

month first depending on year(if leap feb has 29) then day depending on month

if you want to extract the last two digits of a number, you can just work on the integer using modulo

2014 % 100 = 14

 

this way the user can enter the year in whatever format, because

2014 % 100 = 14

14 % 100 = 14

Thank you SO MUCH. I completely forgot about that operator, and thanks for the simple solution. Much appreciated.
