Download link for a good {free} C++ IDE that runs in Windows7 64bit?

Have some serious OOP things this semester, and desperately need a C++ compiler/ IDE to test the programs I write.
I'd need a ANSI compliant compiler, one where i can use #include<iostream> [NOT forced to use iostream.h], and one that can run in 64bit Windows 7.
Can someone please provide me a link to such an IDE?
Thanks :)
 
Visual C++ 2010 Express will do fine, or you can get mingw32 compiler and either NetBeans/Eclipse as the IDE (both have C++ support), though for just school even a good text editor like Notepad++ might suffice as IDE.

The 2010 version of VC++ doesn't support the most recent (C++11) standard, but it's reasonably compliant with the previous standard and I sincerely doubt you would actually require any C++11 features. Plus, though I do most of my programming on Linux, I have to admit the IDE is superb.

If you have a valid .EDU email address assigned to you, you could sign up for a free Microsoft Dreamspark account. They have Visual Studio available as a free download.
 
thnx both of you :)
got this friend, she has a Visual Studio 6 working model CD.
Will it do? We aren't required to use all the advanced features of ANSI C++. The only thing I need, is to be able to use namespaces, and header files that don't end with *.h

I installed it, seems to be working, but the simplest program i wrote, is giving errors.
here's the program
code.jpg

#include <iostream>
using namespace std;
void main()
{
class person
{
char name[30];
int age;

public:
void getdata(void);
void display(void);
};
void person::getdata(void)
{
cout<<"Enter name: ";
cin>>name;
cout<<"Enter age: ";
cin>>age;
}

void person::display(void)
{
cout<<"\nName: "<<name;
cout<< "\nAge "<<age;
}
int main()
{
person p;
p.getdata();
p.display();
return 0;
}

And this is the message that i get:

What's up? Something i messed? or problem with the compiler?
I just typed it str8 frm the text book, didn't make it up myself, so i doubt the code is wrong. What's wrong?
Thanks for ur help pals :)

Silly me
it should be
#include <iostream>
using namespace std;
class person
{
char name[30];
int age;

public:
void getdata(void);
void display(void);
};
void person::getdata(void)
{
cout<<"Enter name: ";
cin>>name;
cout<<"Enter age: ";
cin>>age;
}

void person::display(void)
{
cout<<"\nName: "<<name;
cout<< "\nAge "<<age;
}
int main()
{
person p;
p.getdata();
p.display();
return 0;
}

i wrote main () twice :P
this is working now. thnx :D
 
I imagine it should do.

As for the errors in your code, you have two main functions; you can only have one (and it should return and int and take an int and an array of char*s as arguments).

Also, when a function takes no arguments, you should just have empty parentheses rather than void; the latter is C style and I don't know if it's even supported in C++, it's certainly not recommended practice.

EDIT: Oh, you fixed it yourself - never mind then :)
 
Got another silly question :P

#include<iostream>
using namespace std;
void main()
{
cout<<(3/2);
}
Why would it print 1, instead of 1.5?
How do i get it to work with floating points??
thnx!!
 
By default, 3 and 2 are treated as integers, so that performs integer division (i.e. the remainder is discarded). To get 1.5, do 3.0/2 - the .0 at the end makes it a double so you'll be doing floating-point division.

You're right, 3.0 instead of 3 WORKS!!
It does not remove the decimal part if i use 3.0;
Thanks man :) :good:
