Having problems while running C or C++ program ?

Many a time beginners are faced with the problem while running a C or a C++ program. The common being not able to compile and run it. The error's like

Unable to open include file 'IOSTREAM.H'
Unable to open include file 'CONIO.H'
Unable to open include file 'STDIO.H'

It seems to give an error for every file included using #include. Its common to have such errors since people usually place the TurboC or TC or TurboCPP folder according to the location they prefer in the partition.

Method 1 :

Placing it in the partition where Windows is loaded could solve this problem.

Locate the folder TC or TCPP or TC++ or TurboC
the above names may differ according to the source you have 
acquired it from
Copy the folder
Go to the partition where you have installed your Windows 
operating system
Open the partition
Paste it 

After installation the path should be like [drive :]\TC . Where drive is the letter of your partition which in most of the cases is C. You can use the below method if still you aren't able to run the program.

Method 2 :

Alternatively if you dont want to place the folder in windows partition you can follow the steps below to solve the problem.

Locate the TurboC or TCPP folder
again names vary according to sources you have acquired it from
Open the bin folder
Click TC.EXE
In the IDE or the window you are working in locate the menu bar 
at the top
Click on Options in the Menu bar
Click on Directories
Now besides Include Directories type the whole path to where you 
TC is located. For example
[drive : ]\path\tc\include
Now do the same for the text field located besides 
Library Directories. For example
[drive : ]\path\tc\lib
For Source and Output directories do the same. For example
[drive : ]\path\tc

Note : By default the path specified are relative paths and hence dont work in partition's other than Windows. When you place your TCPP or TurboC folder in location other than Windows partition you have to explicitly mention the path to directories.
