Put a counter in the loop. Display the results before the function returns, or pass it back as reference parameter.

Proper indenting would help you find the error.

while (!found && first <= last)
{
middle = (first + last) / 2; // Calculate midpoint
}
if (array[middle] == value) // If value is found...

I'm not sure how your question relates to the OP's problem. But, if you were handling multiple rows, which might have different states in each row, you simply copy this formula row to row, and Excel...

Oh, it's not really that hard. You could do this if you were writing it in program code, and it's just a little jump to do it in Excel.

A cascading if...else block does it.

Look at the order you are using the search functions.
You call the function, looking for a fixed number.
You then ask the user to enter a search value.
You then test the result of your search, for...

How about:

You can search on DaniWeb why the eof( ) usage is not advised.

I get no errors on that line, but several other compiler errors and warnings do come up (Visual C++ 2008)

Have you in fact posted the latest version of your code that is giving you problems? Have...

I'm surprised you get even that. Firstly, if you're getting warnings from your compiler, pay attention to them and fix the problems.

#1 - it's int main( ) , not just main( )

#2 - quotatot is...

You should check where the program crashes, and read the error message(s).

Check your arguments closely - what's being used here, and what is being used without having a value assigned?

First, the code would be clearer if your variable names better expressed what they were.

What's "total"? The input of distance driven should be "miles", not "mpg". mpg = miles / gallons better...

What's the largest value that can be stored in a long int?

How does that limit compare to the value you're trying to stuff into a long int?

results[0]= x * sin (x);
x is an array - it cannot be used as the operand of a multiplication nor as the argument to sin( ).

Did you mean to say results[i]= x[i] * sin (x[i]);?

Actually, it does make a difference. The declaration outside of main( ) is globally visible and modifiable. This is generally to be avoided, especially in beginning programs, as it may cause the...

switch blocks are not good for doing range based decision making. You have to be able to do exact matches to integral types, which is often, as you surmise, way too much work.

Use if...else if......

Your new function, which still has the { } problem jonsca pointed out, will return immediately after the first number is read in, depending on whether it meets the 10-500 test or not.

To read just 5 characters at a time to your array, you could use getline( ).

I would do a search of the daniweb c++ forum and find this problem discussed many, many times.

( I wish profs would be a bit more creative and come up with some new assignments.)

Hmm, bet you made the file in notepad and named it "test.txt", and Vista added the other .txt. Or VS might have done the same thing.

That's why I like to set my systems to display the file...

What compiler/IDE are you using? That would help us to tell you where the input file should be located. Are you running this from the IDE or directly in a command window?

Long time ago I used this article (http://msdn.microsoft.com/en-us/magazine/dvdarchive/cc301454.aspx)as a reference to do such.

Unfortunately, it seems the supporting code is not available at...

Here's your code, translated in to C++.

#include <fstream>
#include <iostream>
using namespace std;


void READFile(char* filename)

int num;

And your question is?

Read the problem thoroughly. List what you know, what's to be input, what you're to do with it.

Then start listing the steps to accomplish the task. Voila, you're done.

RTE, I think you're reading too much into this. The airline reservation/seating problem is a common assignment in beginning programming course, as evidenced by the many times it's come up here.

Read the full assignment. It should all be there.

You could pass the username and password arrays (or the single array of user objects when you make a class) to the checkDetails( ) function. That way you don't have the arrays in global space...

Yes, you could use a loop to print only up to 22 characters. Be sure to first test the length of the actual string content, and limit your loop to 22 or the string length, whichever is less.

So, your function must:
1. Display the menu. What are the options in this program?

2. Ask the user to make a selection from the options available. Usually you will take this in as either a...

I think a better approach would be just use getline to grab all of a line into a large string, then print out the first 22 characters that appear (or less if the line's not that long.)

You can...

For your array, if the problem is given as a set size, just declare a local array, as you show int plate[10][10]; for example.

If no specific info is given for initial state of interior nodes,...

Why are you doing two input actions in the loop?
The first, in the while condition, reads the word and stops at the newline. The getline will read and discard the newline, storing an empty string to...

Sure you could modify during runtime. And make allowance to store the parity bit(s) as well.
