5. Smallest of 3 numbers without using Comparator operator.    bytes.com

Gannon11 says: Yes, but to determine which result was smallest, you'd have to use...a comparison operator. Why couldn't the 3 products be printed out as shown and then cout<<"Which int: "; cin>>numsmall; user chooses n1 or n2 or n3 on the basis of which n is common to two smallest products cout<<"The smallest int is: "<

6. complex number operator question    bytes.com

Suppose you have a complex number class, and you overload conversions to double by only taking the real part. You also overload operator* to do complex multiplication. You then write: complex a(...); complex b(...); complex c = a*b; Then the compiler complains that it is ambiguous because it doesn't know if you want complex*complex, or to do the case to double ...

All, First post. Hope to stick around. I got an assignment yesterday dealing with bits and bytes and C. There's a variety of functions we have to write that replicate operators using bitwise operations. The one I'm stuck on (this time, anyway...) is one that accepts to integers and then returns 1 if the first is greater than the second. We're ...
