wat does +++ do???

Code:

main() 
{ 
    int a=10,b=20,c; 
    c = a+++b; 
    printf("%d",c); 
}

output is 30..

how does this work???

 

yes sir...forgot dat was a post increment..
so a+b n then a is incremented..
thank u sir..

 

Just to add...
Maximum munch rule is follwed here.
ie: It uses
(a++ ) + b
instead of
a + (++b)

 

thank u for the info..
