 |
|
Hey Guys,
When i try to compile this code:
| Code: | #include <iostream.h>
#include <iomanip.h>
#include <fstreamh.h>
//Functions Prototypes
int displayLine();
float calcSquare(float);
float calcHalf(float);
int main()
{
//Declare And Initialize Variables
float numberInput = 0.0;
float numberSquared = 0.0;
float numberHalved = 0.0;
//Accept Input From User
cout << "Enter A Number: ";
cin >> numberInput;
//Call Functions To Do Calculations
numberSquared = calcSquare(numberInput);
numberHalved = calcHalf(numberInput);
ofstream outFile;
outFile.open("Beginner Program1.dat");
//Display Output Items
displayLine();
cout << setprecision(2) << setiosflags(ios::fixed|ios::showpoint);
cout << "Result of Calculations" << endl;
outFile << "Result of Calculations" << endl;
cout << "Square of Number: " << numberSquared << endl;
outFile << "Square of Number: " << numberSquared << endl;
cout << "Half of Number: " << numberHalved << endl;
outFile << "Half of Number: " << numberHalved << endl;
displayLine();
}
int displayLine();
{
cout << "----------------------------------------"
} |
It returns an error because there is no such file or directory for the .h in the includes, but when i take out the .h everything they are meant to support is now undeclared, so is there like a code for these includes that i might need?
Thanks Alot

If there is no such file or directory, then you're missing those files. Google, download, put them in your includ directory.

| Code: | //Here are some fixes
#include<iostream>
#include<fstream.h>
using namespace std; |

No, you wouldn't. These are files used by the compiler that it has to have. You just have to put them in the include directory of your compiler, then you're set.

It's only a waste if you're only using cin and cout. I put it anyway, but you don't need to use the whole namespace when your only using two functions in the namespace you may as well just put std::cout std::cin.

Download the Microsoft SDK from the other thread wiccaan posted it in. Then go to the options and find VC++ Directories or something like that and add the *SDK Location*\Include Folder to the list of includes and in the *SDK Location*\Lib to the list of lib's and finally add *SDK Location*\bin to the list of Executable files

I didn't understand all that, but I tihnk you don't know where the VC lib/include directories are? Go into options, it should be in there. Other than that, go to the VC directory and there should be lib and include directories.

Examples of using SDKs. Do that for the normal SDK. I used the DirectX SDK as an example.
