Hi, your code is very unprofessional. I would like to share with you the things you need to improve your code. 1) Name variables to something related to the subject. This is so you can easily understand what each does. 2) Add some useful comments in the code. You can easily forget what a certain thing does. 3) You used "int main()" but did not return a value. (my compiler caught this as a "warning". Warnings are very important so treat them like errors. (If this comment was disrespectful, please report it.)

This code is very usefull for me. (I am a beginner too) (If this comment was disrespectful, please report it.)
i agree with everything the first guy said, however not about returning a value from main as, in ANSI c++, the compiler automatically assumes it's returning 0. and you'd definately be better off learning to use switch statements for use anytime you have a console menu.

I agree with RyanD, int main() does not need to return a value, but just for neatness's sake, use void main(). (If this comment was disrespectful, please report it.)

nvm, dont use void main, I spaced..lol (If this comment was disrespectful, please report it.)

heres a tip, from when i made my first calculator program. instead of having someone hit 1 for add, 2 for subtract, 3 for multiply, and 4 for divide, just have them enter the first number of the equation: E.X. 5, then enter a sign, which will be a char varible. a char is a character, like *. to make a char, type char VARIBLENAME; just like an int or long varible declaration. to test the chars, just put an if(VARIBLENAME=="/"){ answer=(firstnumber/secondnumber); }
//that one up there would test if the person entered a / which would be division. after you have the char inputted, input for the second number. if you have any questions, just ask me. (If this comment was disrespectful, please report it.)
I'd say that you did a good job for your first program. But, you didn't (as the first guy stated) name your variables. Next time put comments in your code. And it is definately a good idea to get used to commenting just about anything you code. Whenever you use int main(), ALWAYS return a value. Most of the newer compilers just assume that you mean to return a value of 0, but not every compiler is the same. And that first guy was VERY right about treating warnings as errors! Anyways, it was a good first attempt. I would rate it higher then 3 because you DID succeed in making a calculator program, but you didn't do it very well. (If this comment was disrespectful, please report it.)
I agree with everyone, but use a do-while loop so the process can be run again.
do { *main code* cout<<"Another Calculation? (y/n)"< cin>>ch; }while((ch=='y')||(ch=='Y')); this will run the specified code until the user inputs overwise -SiF (If this comment was disrespectful, please report it.)

I have two things to say:
1. Good code for being a newbie (gotta start somewhere). 2. It would help other newbies.

Ummm, good code for begginer, but when I tried to compile it gave me at least 5 errors, but maybe it was my compiler, mine is Dev-C++ (If this comment was disrespectful, please report it.)
I'm just moving from VB to C++ and I got no idea how to operate C++, or how it works.
Now at least I have some ideas. thanks. (If this comment was disrespectful, please report it.)

Works well but dosen't check for divide by zero error....! (If this comment was disrespectful, please report it.)

A NooB Question in C++, what does
using namespace std;
Stand for???? E-mail me please (If this comment was disrespectful, please report it.)

This is just a tip for your next program. Instead of having the user "press any key and enter to exit", you can replace
cin >>n; if (n==' ')
with
system("pause");
This will allow the user to press enter only, without entering another character. Hope this helps.

I'm a beginner too, but I looked at your code and all I have to say is I could do better. If your bare bones beginner, I can understand, but if your a beginner, like me, you should really take the advice from the guy below me. Except to add on to his statement. Use void main because you aren't returning anything, and use a switch statement. Multiple if statements are a waste of code and it also makes the code look ugly.

Why dont u use switch statements? It will save u loads of writing. :) Im a noob too (If this comment was disrespectful, please report it.)

good try for a beginner. the last par where you use
if (n==' ') { return 0; }
u can use a better code. include the file
then instead of if (n==' ') { return 0; } u use system("pause"); return 0;

HI.my guid PLease send me from robotics code on c/c++ becuase i want for programming robotic. Thnaks for your help

This code is excelente, i started today with C++, and it is usefull, thanks!. (If this comment was disrespectful, please report it.)
Hmmm.. I agree with the variable naming... another thing you should do is use a try{..} and cath{..} because if you type in a string, then your program will crash. (If this comment was disrespectful, please report it.)
Try using several methods like switch/case or using less variables,you will learn many things this way! (If this comment was disrespectful, please report it.)
thank you for sharing this code to students like me... i get some ideas how to create my own codes (If this comment was disrespectful, please report it.)
