Thread: Formatted input

I want to input two variables like a/b.One book suggest this as

Code:

int a,b;
char dummychar;
cin>>a>>dummychar>>b;

Can anyone explain why above code gives the desired result.Also is there any other way out.In C we used to do it as

Code:

scanf("%d/%d",&a,&b);

Also please give me a link to other aspect of formatted input in C++.
