Arguments

Preprocessed source files are output to the compiler.
Description
This option causes the preprocessor to send output to
stdout
. Compilation stops when the files have been preprocessed.
When you specify this option, the compiler's preprocessor expands your source module and writes the result to
stdout
. The preprocessed source contains #line directives, which the compiler uses to determine the source file and line number.
IDE Equivalent

Alternate Options

Example
To preprocess two source files and write them to
stdout
, enter the following command:
On Windows* systems:
icx /E prog1.cpp prog2.cpp ! specific to C++
dpcpp /E prog1.cpp prog2.cpp ! specific to DPC++
On Linux* systems:
icpx -E prog1.cpp prog2.cpp ! specific to C++
dpcpp -E prog1.cpp prog2.cpp ! specific to DPC++
