Is this a reasonable use of the ternary operator? [closed]

Answer 1

I use ternary operator when I need to call some function with conditional arguments - in this case it is better then if.

Compare:

printf("%s while executing SQL: %s",
        is_sql_err() ? "Error" : "Warning", sql_msg());

with

if (is_sql_err())
    printf("Error while executing SQL: %s", sql_msg());
else
    printf("Warning while executing SQL: %s", sql_msg());

I find the former is more appealing. And it complies to DRY principle, unlike latter - you don't need to write two nearly identical lines.
