I know, but if it's

variable = value

Then wouldn't that be working from left to right? C assigns right to left

the calculation of value must occur first

I was a late bloomer on this one... I was wondering when you guys were going to mention this...

I can't believe I missed that. :blink:

hehe, and i think for most people who have programmed for a while

value = variable <---- is just wrong on so many levels

variable = (value with possible workingout's) < much nicer

i feel it is also easier to read as if you have a lot of calculations over multiple lines its easier to look at the start of a calculation to find the variable then at the end.

One more thing - if you use an array for the months, it'll make it so much easier:

(Toggle Plain Text)

int month;
std::string months[12] = "January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December";
char mon[10];

And later:

(Toggle Plain Text)

mon = c_str(months[month]);

Thanks guys, my following question:

If user enter 1 then this month represent January:

How could I assign the variable mon to be equaled to January?

(Toggle Plain Text)

if (month == 1)

mon = "January";

But this wont work.. I don�t know why.

Benoit · Oct 11th, 2004, 4:42 PM

Use strcpy(mon, "January"); make sure mon is big enough to hold the word

TecBrain · Oct 11th, 2004, 4:45 PM

Is that right: :unsure:

(Toggle Plain Text)

int date;
 int month;
 int year;
 double mon;
 
 cout << "Please Enter the date(EX: 1 or 2)" << endl;
 cin >> date;
 cout << "Please Enter the month(EX 1 or 2)" << endl;
 cin >> month;
 cout << "Pleae Enter the year(2004 or 2003)" << endl;
 cin >> year;
 
 
 if (month == 1)
 strcpy(mon, "January");

use Ooble's array to do it, it's much cleaner and easier. I agree with his method.
