If [icode]menu()[/icode] returns a value, then return the value. It should be a [ICODE]char[/ICODE], not [ICODE]void[/ICODE], function.

[QUOTE=Alibeg;818401]@csurfer i thought that you cannot read a string like [icode]scanf ("%s", stu_name[j]);[/icode] if you defined [icode]stu_name[/icode] like [icode]char stu_name[MAX_LENGTH];[/icode][/QUOTE] Yes you can, but you shouldn't. If your string has a SPACE in it, you only read up to that space. And reading a string with [ICODE]scanf()[/ICODE] is identical to …

[QUOTE=siddhant3s;818559] BTW,[icode] char chr_digits[] = {'0', '1', '2', '3', '4', '5', '6', '7', '8', '9', '\0'};[/icode] is same as [icode] char chr_digits[] ="0123456789";[/icode][/QUOTE] True. But based on the code you don't seem to need a [I]string[/I], just an array of characters. So [icode]char chr_digits[] = {'0', '1', '2', '3', '4', …

I'm not sure how adding if statements for edge checking makes the code simpler. In my experience, additional code always complicates, rarely simplifies, readability.

IMAO, giving bad rep then giving good rep to nullify it is asinine. If you think they deserve bad rep, give it. If you're concerned about their rep points going in the toilet, don't give it. The only thing I've seen in this thread that makes even a little sense …

First, please learn to [url=http://www.gidnetwork.com/b-38.html]Format your code[/url] so we can read it easier. You need to store each factor in an array as you generate them. Using your 100, you first generate 2. Save it in the array and you have 50 left. Run the loop again on the 50 …

The idea behind c-strings is that they end with a '\0' character. You have defined the array to be 11 characters then ask for 11 characters. There is no room for the \0. You must only read 10 characters. And on a style note, if you ask for the string …

You're reading into an integer and each line contains an integer. Even though you didn't explain what you actually want I assume you mean to read each individual [I]digit[/I] into the [B]j_mapKey[/B] array. If so, read each digit as a [I]char[/I] and convert to an integer by subtracting 48.

You really need to tell us the [I]real[/I] problem, which is "I cannot get the program to compile. The error message I get is..." You cannot define a function within another function as you are doing. [B]round()[/B] cannot be within [B]main()[/B].

Making a change to [B]RF[/B]'s equation will give you the ability to get random numbers in [I]any[/I] range. Add a [icode]start[/icode] and a [icode]range[/icode] variable: [icode]((int) (range * (rand() / (1.0 + RAND_MAX))) + start) [/icode] So, if you want numbers from (and including) 3 through 10, [icode]start[/icode] is 3, …

There is no built in way. Easier? Can't think of anything easier than checking characters.

Since you never initialized [ICODE]command_array[/ICODE], it starts out with junk in it. Then you added your input to that junk. Is the first parameter to [ICODE]execvp[/ICODE] supposed to be a single character? That's what you are passing. After making changes you should repost the code so we can see it's …

The problem with [B]AD[/B]'s solution is you never really know when you're at the beginning of a line. You can: Read a complete line. Test the beginning for the word in question. If found, there are many ways to 'parse' the line. 1) looking at each character and dealing with …

[QUOTE=RexxX;800926]Well, I want to know how to insert a full string into the array of strings.

Start by writing a program to determine the prime numbers less than 1,000,000. Then modify the program to test the differences.

I hope you get a good grade on the assignment, [B]Comatose[/B]

Actually, you can't assign a char to a string, but you can [I]add[/I] a char to a string. A minor change to you program above: [code=cpp] int main() { string user_input; string first = ""; getline(cin,user_input); first += user_input[0]; cout << "Frist character is " << first << endl; return …

[QUOTE=niek_e;796511]There are a few thing wrong with your code : - you're incrementing 'i' twice in your word_count function. That's not good.

[QUOTE=niek_e;796511]- Why use …

Not a clue what you are talking about.

To expand on what [B]vmanes[/B] said, create a 2D array, something like [ICODE]inputbuffer[4][250][/ICODE] (4 lines, 250 chars each). Reading each character, load the characters in the array. When you reach the end of one line from the file, add a \0 character and point to the beginning of the next …

Word Perfect plain or regular?

getline will read the entire line, then you'll have to break up the line read into its individual strings. Alternatively, you can use >> to read in each individual string. >> will stop reading at whitespace.

Can't be done. Change your message to [B]Press ENTER to continue[/B] and just use the standard I/O functions.

My guess would be that this loop [code=c] for(loopcounter=9; loopcounter!=NewRank; loopcounter--) { [/code] exits when [I]loopcounter[/I] equals [I]NewRank[/I] so [code=c] if(loopcounter==NewRank) { ListToBeChecked[loopcounter].TimeTaken = Time; strcpy(ListToBeChecked[loopcounter].Username,UsersName); } [/code] is never executed. Also, [url=http://www.gidnetwork.com/b-57.html]see this[/url] about [ICODE]fflush(stdin);[/ICODE] [url=http://www.gidnetwork.com/b-56.html]and this[/url] about [ICODE]gets(UsersName);[/ICODE]

The problems I see in that function: 1) using [ICODE]getch()[/ICODE] -- [url=http://www.gidnetwork.com/b-43.html]see this[/url]. 2) recursively calling fnAddDepartment(); because an invalid department entered. Should simply loop back to reenter the value. 3) Your formatting does not make it easy to read the function. [url=http://www.gidnetwork.com/b-38.html]See this about formatting[/url].

Who says the 'buffer on the stack' is formatted properly for [icode]sscanf()[/icode]?

The only correction I can see, and it's minor, is that [I]postconditions[/I] is not a valid English word.

You said the temperature in the file is in the format C23.4 F74.7 Where did you read the C or F? Where did you test the C of F to decide if you need to convert?

Your shuffle seems backwards to me. Assuming [I]card[/I] values mean something like 1 = 2 of clubs 2 = 3 of clubs ... 13 = A of clubs 14 = 2 of Diamonds ... 52 = A of Spades I'd change the shuffle to something like this... Fill an array …

That's how sscanf works. A decimal is illegal for integers so the translation ends. You'll have to reconsider how you read/translate the file. Also, consider these problems: [url=http://www.gidnetwork.com/b-66.html]see this[/url] about [icode]void main()[/icode] You've defined [icode]c[][/icode] to be 10 characters. How many characters are in the first line for [i]textfile.txt[/i]? And …

Usually you change the buffer in memory, then write the whole buffer to the file after all the changes are made. Don't try changing the file as you change the display.

Now I'm completely confused. In your first post you state [quote]am trying to append to file but its not going correctly[/quote] The problem is you open the file for append (write at end) then try [I]reading[/I] from the file.

So far, I like the look although I haven't explored fully. The first thing I noticed that I'd like corrected is putting the "Community" tab back on each page rather than accessed only at the bottom of the main forum page.
