[QUOTE=mitch9654;1185232]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 …

[QUOTE=miskeen;1180494]Hello, I have to use an array, but its length is unknown at the beginning of the program. Is it possible to create such array and after that give it the desired length? Thank you![/QUOTE] If the length is varying, I'd recommend using vectors instead as they can change size …

what you're looking for is an overloaded function Your first function (for char's) would look like this: [CODE=cpp]void write(char c) { ... }[/CODE] Your other function (the overloaded one) should look like this: [CODE=cpp]void write(const char* c) { ... }[/CODE] The one that's needed at the time will automatically be …

[QUOTE=heynow12;1179247]max_val is supposed to tell the program how many numbers will be inputed. Then the size array x is the value of max_val...if that makes sense.[/QUOTE] Like what [B]Ancient Dragon[/B] is hinting at...what is max_val equal to when line 9 is to use the max_val? An array must have a …

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. I'm just excited to see something like this finally show up as I had been looking for this for a few months now (on-and-off) and stumbled upon it today :) [URL="http://codepad.org"]codepad.org[/URL] is "an online compiler/interpreter, and a simple …

Or if you'd like to connect two variable strings use "append" [code=cpp] #include <string> #include <iostream> using namespace std; int main(int argc, char** argv) { string one = "Hello "; string two = "world!"; one.append(two); cout << one << endl; } [/code] The above would ouput: [code] Hello world! [/code]

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 …

Thanks [B]vijayan121[/B]! I'm going to have to play with this a bit more today to really understand how to use it myself I understand your example, now. But I had trouble trying to come up with it on my own Thanks again! You've really helped me in understanding this a …

[QUOTE=lotrsimp12345;1163697]one piece of advice switch statements will only accept built in types of C++. gl.[/QUOTE] Yep - a switch statement will not, for example, accept a string variable for comparison. It will, however, accept a char or int variable type Another thing that's easy to miss or overlook is to …

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 …
