Revisions to C/C++ Passing Macros that take arguments on the compile line

Add how to show brackets

The macro should be defined without parameters.

gcc -DHASH=hash_fcn1 program.c -o program

If you wish to pass parameters, the brackets need to be escaped

gcc -DHASH\(X\)=hash_fcn1\(X,55u,33u\) program.c -o program

The macro should be defined without parameters.

gcc -DHASH=hash_fcn1 program.c -o program

If you wish to pass parameters, the brackets need to be escaped

gcc -DHASH\(X\)=hash_fcn1\(X,55u,33u\)

The macro should be defined without parameters.

gcc -DHASH=hash_fcn1 program.c -o program

If you wish to pass parameters, the brackets need to be escaped

gcc -DHASH\(X\)=hash_fcn1\(X,55u,33u\) program.c -o program
