Compilation /Running and Debugging the Solution

• Go to Compile Menu and Press the Compile for the Compilation of the code.
• If Successful Compilation is done then Run the Code Using ctrl + F9 key.
Before Compilation, following steps are to be followed:
• Step 1: Create a folder in either E or F drive with your Id Number or Name Followed by
RollNo.
• Step 2: Start the TC (Turbo C) from Desktop Icon or Go To Directory D:/TC/BIN/ and
run tc.exe . An Editor will be start.
• Step 3: Click on File Menu --> New. New (.cpp) file will be created. Again Click on File
-> Save. A dialog box will open. Write the path to your directory e.g. E:\CCN_Program
\FileName.CPP and Press OK. Now your cpp program will be saved in your directory.
• Step 4: Go To Option->Directories Check That Include Directory is set As D:\TC\Include
and Library Directory is set To D:\TC\LIB
