From man fopen:
RETURN VALUES
Upon successful completion fopen(), fdopen() and freopen() return a FILE
pointer. Otherwise, NULL is returned and the global variable errno is
set to indicate the error.
That means that your code should be:
FILE *source;
source = fopen("/home/user/test.c", "r");
if (!source) {
printf("fopen error");
exit(0);
};
