[Question]
How do you convert a value defined in a macro into a string?

#define I_AM_NOT_A_STRING 666

...

printf("%s\n",I_AM_NOT_A_STRING );

The code above should give an output of "666".

Change the format code %s to %d. [Hopeful guess! ] haha

hehe that works pero wala nimo giconvert ang I_AM_NOT_A_STRING to a string nice try though hehe

dapat siguro mag-add ko ug constraint na di hilabtan ang printf statement

hint: do some macro manipulation

#define I_AM_NOT_A_STRING "666"

Maybe?

[Sarevok]

#define I_AM_NOT_A_STRING "666"

Maybe?

correct ka hehehe sayop man diay ako question

sige ako iupdate ang question

[Question]
given the following macro definitions, I want to create a new macro named VERSION. This VERSION macro should be equal to "1.0.2" where the 1, 0 and 2 are the variables defined by MAJOR_V, MINOR_V and REVISION_V respectively.

#define MAJOR_V 1
#define MINOR_V 0
#define REVISION_V 2

//#define VERSION //how can I combine the above 3 to form a string of the format "MAJOR_V.MINOR_V.REVISION_V"

no hardcoding of values should be done

w00t! post pa mo og daghan guys! Maka engganyo ni og programming da.

[Moonfall]

#define MAJOR_V 1
#define MINOR_V 0
#define REVISION_V 2
#define VERSION MAJOR_V.MINOR_V.REVISION_V <- idk if it works and I don't know how to convert it into a string?
(Probably, Wrapper Classes?) haha

[KeYmAkEr]

#include <stdio.h>
#define MAJOR_V "1"
#define MINOR_V "0"
#define REVISION_V "2"
#define VERSION MAJOR_V "." MINOR_V "." REVISION_V

int main()
{
printf("%s",VERSION);
return 0;
}

naka ahat kog quickie code sa codepad.org

[KeYmAkEr]

#include <stdio.h>
#define STRINGIFY(A) #A
#define STR(A) STRINGIFY(A)
#define MAJOR_V 1
#define MINOR_V 0
#define REVISION_V 2
#define VERSION STR(MAJOR_V) "." STR(MINOR_V) "." STR(REVISION_V)

int main()
{
printf("%s",VERSION);
return 0;
}

[Sarevok]

#include <stdio.h>
#define STRINGIFY(A) #A
#define STR(A) STRINGIFY(A)
#define MAJOR_V 1
#define MINOR_V 0
#define REVISION_V 2
#define VERSION STR(MAJOR_V) "." STR(MINOR_V) "." STR(REVISION_V)

int main()
{
printf("%s",VERSION);
return 0;
}

^ win

ang trick kay expanding macro definitions
