ok this is my code
// If statements.cpp : Defines the entry point for the console application.
#include <iostream>
using namespace std;
int main()
{
int age;
cout<<"Please input your age: ";
cin>> age;
cin.ignore();
if ( age < 100 ) {
cout<<"You are pretty young!\n";
}
else if ( age == 100 ) {
cout<<"You are old\n";
}
else {
cout<<"You are really old\n";
}
cin.get();
}
#include "stdafx.h"
int _tmain(int argc, _TCHAR* argv[])
{
return 0;
}
as most of you know im new and there are no errors. but when i use the debug feature it doesnt say anything when it is supposed to say an answer. how do i make it show up? i use microsoft visual c++
First of all, please choose better names for your topics. A question mark doesn't make a good title.
Secondly, use the [source] [/source] tags to format your code.
And last but not least you seem to have two main functions in your code. Remove the one that contains return 0;

I'll assume you're using visual studio.
Select File->new->project
Select Win32 Console App and type in a name
A wizard should pop up click next
On this page make sure that you
CHECK "Empty Project"
UNCHECK "Precompiled Headers"
Then click finish
This should make a project without any of the Visual Studio default stuff
Now select File->new->file
Select C++ file and type in a name.
This will give you a totally empty cpp file.
Type the code you posted in there up until the #include "stdafx.h"
That should work
What I've walked you through is creating a truly empty project. If you aren't careful Visual Studio enables several things that can mess up simple projects like precompiled headers and the unicode/ansi _t macros. A truly empty project should avoid most of those pitfalls

do i use #include "stdafx.h"?
and now it says it wont be built. there are no error reports though.
my new code
// If statements.cpp : Defines the entry point for the console application.
#include <iostream>
using namespace std;
int main()
{
int age;
cout<<"Please input your age: ";
cin>> age;
cin.ignore();
if ( age < 100 ) {
cout<<"You are pretty young!\n";
}
else if ( age == 100 ) {
cout<<"You are old\n";
}
else {
cout<<"You are really old\n";
}
cin.get();
}

Everything that begins with '#' is a C preprocessor directive and should placed outside of and before the main() function, usually the first few lines of your code.
...etc
also I notice in your code you haven't returned 0 at the end of your int main(), it's not vital but it is good c++ practise.

According to the standard main implicitly returns 0 in the absence of any other return statement - so one might consider that the more idiomatic way of doing things in c++
@m09868 If you followed my directions and have an empty project without precompiled headers then DON'T include stdafx.h - it's a precompiled header and you don't want/need it
