### /Pe Compiler Option

Syntax: | Default:
/Pe[+|-] | /P-

Use /Pe to run the preprocessor only, and suppress generation of #line directives in the preprocessor output. The output file has the same name as the source file, with the extension .i.

Specify /Pe- to run the preprocessor only, and generate #line directives in the preprocessor output. The output file has the same name as the source file, with the extension .i. /Pe- is equivalent to /P[+].

By default, both the compiler and preprocessor run, and no preprocessor output is generated.

/P, /Pc, /Pd, and /Pe can be used in combination with each other. For example, specify /Pcde to preserve comments, suppress line directives, and redirect the preprocessor output to stdout.
