How do i store a cin value to two different variables?

this is what i did but its not working.

I assume you don't actually want both the variables to contain the same thing?
Depending on what exactly you are trying to read here, you could set a delimiter to read what you want

yeah its gonna take in a month/year

RevanOP•9/30/22, 11:01 PM

and they are seperated by a /

Eakam•9/30/22, 11:01 PM

So read until the / to get the month

Eakam•9/30/22, 11:02 PM

And then read until the end of the line to get the year

RevanOP•9/30/22, 11:05 PM

so this?

RevanOP•9/30/22, 11:07 PM

yeah no that does not work

Eakam•9/30/22, 11:16 PM

Oh, that's not what I meant

RRevan this is what i did but its not working.

The thing with using cin.ignore('/') first is that it will read and discard everything until it finds the '/'

RevanOP•9/30/22, 11:17 PM

So I have to use cin.ignore(‘\n’) in the same line to ignore the end of the line ?

Eakam•9/30/22, 11:18 PM

ignore does not ignore one thing. It ignores everything until it find what you specify

RevanOP•9/30/22, 11:19 PM

So I don’t want it to ignore the first two numbers before /

Eakam•9/30/22, 11:20 PM

Yea, you want to read those number before you ignore the '/'

RevanOP•9/30/22, 11:21 PM

cin>>variable1>>cin.ignore(‘/‘)>>variable2 ?

Eakam•9/30/22, 11:28 PM

I am not sure if that syntax will work but that is what you want to do

Eakam•9/30/22, 11:36 PM

Actually that might not work since the first argument to ignore() is supposed to be the number of characters you want to ignore

RevanOP•9/30/22, 11:50 PM

this works for me but the assignment says i need to do this all in one line

RevanOP•9/30/22, 11:50 PM

is there a short form for this?

Eakam•9/30/22, 11:57 PM

Haven't done c++ in a while but you can't chain these?

RevanOP•9/30/22, 11:57 PM

my c++ knowledge is about 1 month. whats a chain?

RevanOP•9/30/22, 11:57 PM

unless chaining is c program thing as well then its my fault

Eakam•9/30/22, 11:58 PM

Like this cin >> tempExpMon >> cin.ignore(...rest of code

Eakam•9/30/22, 11:58 PM

Same way you have put the ignore and tempExpYear on one line

Eakam•9/30/22, 11:59 PM

Though if that doesn't work, you could read that character into something else I suppose

RevanOP•9/30/22, 11:59 PM

yeah i get this when i try that

Eakam•10/1/22, 12:00 AM

Ah, so it isn't possible to do that. Unfortunate

RevanOP•10/1/22, 12:00 AM

oh well it works the other way so its all good

RevanOP•10/1/22, 12:00 AM

thanks for all the help
