c - Redefinition of Assignment Operator -

it in understanding several languages use := assignment operator. implemented possibly avoid confusion == operator. seemed valid point me, thinking of how implement in language c. here thinking.

#define := = // ... later on  int x := 4; 

although work (if preprocessor supported syntax), still allow me away using = operator. question is, is there way "flag" symbol or operator / there way prevent use of defined operator or symbol? again, here thinking, don't know syntactical / semantical legality of this.

#undef = 

#define := = 

a macro name can identifier. i'd quite surprised if c compiler accepted definition. in principle, compiler accept language extension, gcc, example, not. conforming c compiler must @ least issue diagnostic.

you works; i'm frankly skeptical. compiler using?

#undef = 

same problem.

i can see (and agree with) point using := rather = assignment operator have been better idea. using preprocessor alter language this, in cases works, idea.

c programmers know = means assignment. reading code can guess := meant assignment, make code harder read.
