macOS create file on desktop c++

[kay.altos]

in c++ trying to do it this way, but it doesen't help

int logA = 0;
FILE* f = fopen("~/Desktop/rr.log","w");
int a = errno;
fprintf(f,"%d", ++logA);
fclose(f);

errno returns 2 - "No such file or directory", there is no file present but it should be created.

please advise

use a fully qualified path ("/Users/yourname/Desktop/rr.log") or import environment variables to get $HOME (use getenv from cstdlib or stdlib.h if you are using C, type "man 3 getenv" in Terminal to see usage)
