    cin to int

    Hello. I'm going back over some C++ stuff. The following program is the usual way I might get user input into a private member of a class.

    #include <iostream>

    class Account {
    private:
    int...
  2. Modification of or simbiosis with old software

    It has been a while since I last posted, so hello.

    I've studied pretty intensely now for about a year and a half. I've spent about 1000 hours in both C and Java, as well as 500 hours in C++ and...

    It seems I was wrong about this. I had assumed that x would get dereferenced first, but it seems that C's order of operations work differently than I thought they did.

    I believe that this is the...

    p and q have been declared as int pointers, so when they are incremented or decremented, they move one int space forward or one int space backward. In an example:


    int num[10] = {1, 2, 3, 4, 5,...

    I believe scanf looks a bit like this:

    // read input stream
    // save next int into variable bird
    // return number of items read
    }
    while printf for example...

    Honestly the two functions part doesn't make sense to me. From what I do understand, your print...

    I have what I think is some valid criticism for your code beyond what you have asked for. I think it is a little bit better if you could keep the scope of a variable within the area which it is...

    if (marks > 0 && marks > 40)
    in this case, whenever marks is equal or less than 40, this if condition will evaluate to false. It may as well be...

    Are you saying that the first full moon which occurred in the year 2000 happened in July?

    Or perhaps that is the full moon you chose as your first. Though you did write:
