You can't possibly get 155.419 from an [I]unsigned long[/I], there is no decimal point from integers. You need [I]float[/I] or [I]double[/I]. And dividing two integers always gives an integer, even if you load it into a floating point number. For example: [code=c] double dval; dval = 25/2; [/code] 12.000 is …

First of all, how about variables named [I]day[/I], [I]month[/I], and [I]year[/I] instead of 1 letter cryptic names. And what is [I]z[/I] for? Are you sure your date validation works? Look up the % operator to get the individual digits of each value so you can add them up. There are …

[code] Make a loop that exits when your value is zero In the loop, calculate the modulo-10 of the value using % (get the ones digit) output the digit divide the number by 10 endloop [/code] That's basically it.

EXTERN simply defines the variable to be accessible from a another source file. Add the EXTERN statement in a local header file and define the variable in only one of the source files. For example, in the [I]error.c[/I] source file you might define [inlinecode]int errCode = 0;[/inlinecode] In [I]error.h[/I] you …

Seems to me you can't actually [I]solve[/I] the equation without some values. Therefore, ask your instructor for more details.

Rule of thumb -- if you need [I]both[/I], use && (and). If you need [I]either[/I], use || (or). Test it by using English (or your native language): is it "[I]if != Q or q[/I]" or is it "[I]if != Q and q[/I]" and you get the operator to use.

I can't see how this code does anything. You have 3 nested [INLINECODE]while[/INLINECODE] loops all exiting on the same condition. And if you [url=http://www.gidnetwork.com/b-58.html]read this[/url] you'll see your condition is wrong ([INLINECODE]feof()[/INLINECODE] is the same as [INLINECODE].eof()[/INLINECODE]) Then in the second loop, you read a single character and output it. …

Count each number you output. After every 6th number, output a newline (\n) Use the % operator.

Not a clue what you are asking, and your code is too hard to read. Try formatting the code using [url=http://www.gidnetwork.com/b-38.html]this info[/url] so we can follow what you're trying to do.

The idea of this forum is to post the code here (properly please) and we [I]all[/I] get a chance to help you. Be sure to [url=http://www.daniweb.com/techtalkforums/thread78223.html]read this first[/url]

Please [url=http://www.gidnetwork.com/b-38.html]format[/url] your code. It's really hard to follow.

DaysFirst = How many days left in the first month DaysLast = essentially the day of the last month - 1 DaysMonth = number of days in each month between the two months Add them all together. Example: 4-May-2007 to 23-Sep-2007 DaysFirst = 27 (31 days in May - 4) …

Personally, I'd read the test answers into a [INLINECODE]char*[/INLINECODE] rather than a C++ [INLINECODE]string[/INLINECODE]. A [INLINECODE]char*[/INLINECODE] must be defined to accommodate the total number of answers necessary, but a [INLINECODE]string[/INLINECODE] will read only the answers on the line. If a student doesn't answer the last 5 questions, the [INLINECODE]string[/INLINECODE] could …

Use a loop to generate as many random numbers from 0 to 25 as you want and add the values to the string. When you get the random number, simply add 'a' to it and you will have all letters instead of 0-25

You need to read each line. The \n\n will take two lines. You can tell the second \n because the line will be extremely short. == may not be good, but < might work better. Depends on how consistent the blank lines are -- extra SPACEs for example.

[QUOTE=tracethepath;458655]sorry i have not read strings yet so didnt know... can you tell me more about that?? thanx...[/QUOTE] Then wait until you read about strings. Until then use [INLINECODE]strcmp()[/INLINECODE] or [INLINECODE]strncmp()[/INLINECODE] which works for your definitions.

Try using a [INLINECODE]while [/INLINECODE]look for the first loop instead. A [INLINECODE]for [/INLINECODE]loop implies you know how many times you need to go through the loop. A [INLINECODE]while [/INLINECODE]implies you exit the loop when some criteria is satisfied, such as you reached the end-of-file ([INLINECODE]EOF[/INLINECODE]). Since you seem to know …

You need to describe the error. No one is going to spend an hour trying to find the error, then pour over [I]your[/I] code to fix it. [I]You[/I] need to describe the error and the circumstances with which it happens.
