ok this is a program i wrote about 3 months ago, scince ive stopped trying to learn c++ out of frustration on finding a decent tutorial. but anyway here it is... please tell me what you think. oh and if you visit my site you can download a compiled version free. its
Digital Resolutionanyway heres the scource code
| CODE |
#include <iostream>
#include <stdlib.h>
using namespace std;
int main();
void aoc()
{
float aocb;
cout<<"\n";
cout<<"What is the radius?\n";
cin>>aocb;
aocb=aocb*aocb;
aocb=aocb*3.141592654;
cout<<"\n";
cout<<"The area is:\n"<<"\n"<<aocb<<"\n";
cout<<" \n";
system("PAUSE");
cout<<"\n";
cout<<"\n";
cout<<"\n";
main();
return;
}
void circ()
{
float circb;
cout<<"\n";
cout<<"What is the radius?\n";
cin>> circb;
circb=2*circb;
circb=circb*3.141592654;
cout<<"\n";
cout<<"The circumference is:\n";
cout<<"\n";
cout<<circb;
cout<<"\n";
system("PAUSE");
cout<<"\n";
cout<<"\n";
cout<<"\n";
main();
return;
}
void radius()
{
float radb;
cout<<"\n";
cout<<"What is the circumference?\n";
cin>>radb;
radb=radb/3.141592654;
radb=radb/2;
cout<<"\n";
cout<<"The radius is:\n";
cout<<"\n";
cout<<radb;
cout<<"\n";
system("PAUSE");
cout<<"\n";
cout<<"\n";
cout<<"\n";
main();
return;
}
int main()
{
int menu;
cout<<"1. Area of a circle\n";
cout<<"2. Circumference\n";
cout<<"3. Radius\n";
cout<<"4. EXIT\n";
cout<<"\n";
cout<<"\n";
cout<<"\n";
cin>> menu;
if(menu==1)
aoc();
else if(menu==2)
circ();
else if(menu==3)
radius();
else if(menu==4)
return 0;
return 0;
}

Sort of a HelloWorld as i see it ^_^

No not really!
it is a formula calculator!
the code is basic but that is because i was still learning c++
hello world outputs garbage on the screen. this does geometry equations for you!

i think its nice for a basic c++ program ^_^ i think he meant "hello world as i see it" as being a ton more basic than the stuff hes into now. if you still want to learn c++ you could download one of those big ebooks or buy a c++ book. i got the book i use off ebay for $11.00 including tax and there was a price tag of 76.95 on the back from some campus bookstore :lol:

I would just put all the functions outsite the main and just have one main that would have the menu with a switch()... Simpler and better structured...
