The ctrace facility expects its input code to conform to the language definition from the 1970's (Kernighan & Ritchie). This script's task is to help in adapting a C89 or C99 program to that syntax.

In particular:

Remove function prototypes, and remove type info from function headings.

Instead, the function arguments will be declared after the closing ) of the function heading, and before the opening { of the function body.

HINT: All the formal parameters in ANSI C have at least two words (a type name and parameter name) and all the formal parameters in K&R C have exactly one word (the parameter name). You can use that fact to identify a pattern, and then use sed's "t" command to repeat for additional parameters, until done.

NOTE: If a parameter is a pointer, the asterisk is part of the type, not the parameter name.

Remove declarations from within the headings of for loops, e.g.
for ( int i = 0; i < 10; i++ )
would no longer declare i to be 'int' here, but somewhere before the loop.

Try to move the declaration for for-loop counters to a new line immediately after the last '{'.
HINT: You can temporarily reverse a file and then use 'sed's pattern and hold spaces to hold the declaration until it is ready for insertion.

The results of this program script should appear on standard output (from which they can be redirected to a file). The resulting code must compile correctly in any C compiler.
