Why Can\'t I Resolve the \'cout\' Symbol in My Eclipse CDT C Project?

Resolving 'cout' Symbol Unresolved Error in Eclipse CDT

When creating a C project in Eclipse with CDT, you may encounter the error "Symbol 'cout' could not be resolved." Despite including necessary headers like iostream, the error persists. This issue arises due to missing system-specific include directories in your project settings.

To resolve this, perform the following steps:

1. Right-click on the project in the Project Explorer and select "Index" -> "Search For Unresolved Includes."
2. Eclipse will list all unresolved includes. Search for them in "/usr/include."
3. Add the containing directories to "C Include Paths and Symbols" under Project Properties. On most systems, this includes adding "/usr/include/c /4.6/x86_64-linux-gnu" for bits/c config.h resolution.
4. Rebuild the index by selecting "Index" -> "Rebuild."

Ensure that the appropriate include directories are included in your project's settings. This enables the indexer to correctly parse iostream and resolve the error, allowing you to use std::cout without further issues.
