Question

I have a macro as such

#define PTF(A,y)    fprintf(file,"%s",A,y);printf("%s %d",A,y);

so that it will print to file and console
so for example i call this macro function

int y=9;
PTF("\nRound %d \n",y);

in a way I need the y=9 to be shown as part of the argument A so my fprintf in file will look like below

Round 9

because I have a lot of changes to make if I were to change this, hence hoping for an easy way out =)

Answer 1

Change

#define PTF(A,y) fprintf(file,"%s",A,y);printf("%s %d",A,y);

to

#define PTF(A,y) fprintf(file,A,y);printf("%s %d",A,y);

Note:

PTF("Round %d",9); will have fprint write Round 9 to the file but printf will still show Round %d 9.

You’ll also have to make sure you only specify one specifier to fprintf
