That is because "st"|"nd"|etc... you are trying to 'or' two string constants, that makes no sense in C++. You need to 'infect' the whole line by wrapping the first one with as_xpr as: >> (as_xpr("st")|"nd"|"rd"|"th") ;

Thanks, it worked. I thought the first as_xpr would infect everything. but i was mistaken. Surya
