Does the variable in your loop condition ever change its value?

[QUOTE=Acidburn]but now im wondering if you could display just + or - depending on what is entered.[/QUOTE]If it's less than zero, print [FONT=Courier New]'-'[/FONT]; otherwise, print [FONT=Courier New]'+'[/FONT]. [QUOTE=Acidburn]is it possible to put the float which is entered into an array?[/QUOTE]Of course.[code]#include <iostream> int main() { float value[3]; int i; …

[QUOTE=MasashiMikamida]/*1*/if (amtnam1=[COLOR=Red]'Uuq'[/COLOR]) atom1=Uuq;[/QUOTE]The message is telling you that [FONT=Courier New]'Uuq'[/FONT] is an illegal character constant. It appears to be an attempt to be a string constant ([FONT=Courier New]"Uuq"[/FONT]), but you don't compare C-style strings with [FONT=Courier New]==[/FONT]; instead look into [FONT=Courier New]strcmp()[/FONT].

Surely your compiler is giving you a message? And [FONT=Courier New]endl[/FONT] is spelled with an [FONT=Courier New]l[/FONT] (ell) at the end, not a [FONT=Courier New]1[/FONT] (one).

Some ideas:[code]#include <stdio.h> struct student { int id; char name [ 32 ]; double grade [ 4 ]; }; void show(struct student *student) { static const char letter[] = "FDCBA"; size_t i; double sum = 0; for ( i = 0; i < sizeof student->grade / sizeof *student->grade; ++i ) …

Two [FONT=Courier New]FILE[/FONT] streams, [FONT=Courier New]a[/FONT] and [FONT=Courier New]b[/FONT], write the same to both.

You forgot to post the most important part -- the actual code. I take it you are not using [FONT=Courier New]"%2d%2d%2d"[/FONT] as a format specifier?

In main(), where does shape get its value? In triangleShape() where do A, B, and C get their values -- and which shape do you mean?

[QUOTE=dalaharp]is there no procedure wherein you can allocate memory by malloc etc..[/QUOTE]Yes. What have you tried?

Consider recursion to "get to the bottom" before starting.[code]#include <stdio.h> void foo(FILE *file) { char line [ 128 ], *ch; if ( fgets(line, sizeof line, file) ) { foo(file); /* * Reached bottom. */ fputs(line, stdout); } }[/code]

Let me summarize the http://www.daniweb.com/techtalkforums/announcement.php?f=8&announcementid=2 announcement: no code, no help. And please use code tags.

[code]#include <iostream> using namespace std; int main() { int num; cout << "Please enter a number: "; cin >> num; while ( num ) { cout << num % 10; num /= 10; } cout << endl; return 0; }[/code]

It might be a little easier to look at your code if it were enclosed within code tags. Hmmm. You open a file and never close it, then you open it.

[code] return sum/12;[/code]Do you want an integer result? Or a float with the fraction not truncated?[code] return sum/12[COLOR=Blue].0F[/COLOR];[/code](This seems to be a recurring theme lately.)

And read the [url][COLOR=Magenta]Announcement[/COLOR][/url]. And do some searches to find out why [FONT=Courier New]void main()[/FONT] is wrong.

average= (tests[0] + tests[1] + tests[2])/3; // assumed fixes cout<< "The average is" <<average <<endl; Lemme guess -- no decimal places? Dividing integers uses integer division.

This thing? http://cboard.cprogramming.com/showthread.php?p=322171#post322171 Paying attention to error codes or phrases may give you something to google. Posting your code will also be helpful if you need help debugging it. (And don't forget the code tags!)

What do you think is the loop condition in the following line?[code]while (ch = Infile.peek() != EOF)[/code][edit]Actually that whole loop is wrong.

For pseudocode it looks like you're on the right track. [For actual code, there are a number of syntactical issues.] But what are you doing with ounces? You ask for it, but never use it. Similarly, are you planning to do something with grams? Please learn to use [CODE] tags.
