Does Hi-tech support pass by reference?

[piedos]

Code:

#include <pic18.h>
#include <conio.h>
#include <stdio.h>

void f1(int * x);
void f2(int & x);



void f1(int * x){

	*x *= *x;
}

void f2(int & x){
	
	x *= x;	
}

int main(){
	
	int a=22;
	f1(&a);
	f2(a);
	puts("Hi");
	while(1);
	
return 0;
}

No problem when passing a value by pointer, but gives error whilst triying with reference.

All errors are about f2 function

[aProgrammer]

references are a C++ feature.

Hi-tech is a C compiler not a C++

but references are just hiden pointers...

[piedos]

if they are c++ specific, why CCS C accepts?

if they are hidden pointers why I can't use
ref++;
for a reference?

if they are hidden pointers, why reference function
 generates less ASM code than a pointer function?

[swapgo]

     C++ alone has this feature. C cannot do the pass by reference. It can do call by reference only.

Try with any of the ANSI C compilers.

 Hi-Tech C is strictly ANSI. But ccsc is not.

 I can say CCSC is user friendly PIC Microcontroller Cross Compiler. I cannot say it is a standard one.
 
 So don't try to conmpare CCSC with any of the standard C Compilers.

 Tryout even with GCC also.

Well, that settles it...

Some features of C++ are supported by some c compilers. For example "//" is also a c++ feature but most c compilers support it! So you have to check the compiler manual for a specific feature you need.
