Hello, I am trying to make a calculator that does multiplication, division, addition and subtraction. My problem is that when I have the two numbers that have decimals it goes wonky. Anyway, that program runs like this: 1. User enters equation 2. Unwanted characters get thrown out 3. If operation …

Long story short... I wrote a CLI events calendar for Linux in C++ (one of my first major C++ programs), and it came to around 2400 lines of code. I've been working on it for a few weeks now getting things just right. I just finished getting a decent working …

I cannot figure out what this error message means? [code] #include <iostream> using namespace std; double max_array(const double x[], int max_val); int main (void) { int i, max_val; double x[max_val]; double array_avg, array_max, array_min; cout<<"Enter likely number of values: "; cin>>max_val; cout<<"Enter values seperated by white space:"; for (i=0;i<max_val;i++) cin>>x[i]; …

I'm using [this website](http://stdcxx.apache.org/doc/stdlibug/33-3.html) as a reference and am modifying some code to (hopefully) have it work the way I'd like it to. I *think* I'm close, but since I have no experience with custom paramaterized output manipulators (and have limited experience with custom output manipulators even) I'm kind of …

Hi, I'm writing a "Date" class and it's fully functioning, including the output manipulators, but the issue I have is when creating a class the has a "Date" instance in it. It, then, doesn't compile because it says there are multiple definitions of the manipulator functions. I'll lay out, below, …

To start off, I am in no way affiliated with this site.

This is just out of curiosity! Does anyone know what is the maximum number of characters that a line of code can have? EDIT: Added more details. Is it possibly possible to make two lines become one? .... This seems pretty odd, I dont know how to explain it, but …

Okay, I've been working on my own version of a Date class and I had it working before but thought I'd try to revise the code a little at a time, after reading "Effective C++: Third Edition" by Scott Meyers I'll start with the code as I'm not too sure …

Question posed by josolanes: [quote]I looked at your thread here: [url]http://www.daniweb.com/forums/thread88255.html[/url] from a couple years back And I'm starting to get a grasp of your first post. I understood how to do the factorial struct really quickly, but the _if and _for statements still make me feel uneasy, though I …

I really need help with this project. 1) Write a program that uses a switch program structure 2) Upon user input your switch structure shall calculate and display one of the three loops for loop, while loop, and do-while loop calculations.

I'll do my best to be as clear as possible about what I'm trying to do. In short, I'd like to know if a switch statement can check multiple variables simultaneously (I have a feeling it can't, but I'd like to confirm). If it can't, can someone recommend a way …
