Then "\ t" This expression is a table character, so it is not an error, itself is an escape symbol of the correct use of the occasion, because there is no error, also forgot to add "@" .
The solution is to precede the string wit

Debugging also has a trap?
I think so. I found one today. If I can find it later, continue to add it.
Since the official writing of Java code in April this year, it has become more and more amazed at the magic of Java, not to mention automatic garbage collection. Even her debugging seems to be full of mysteries (however, maybe my java level is too good), actually a function in the circle can get the final return result of the function, the debugger mu

Error of variable long parameter list and trap--va_arg an unacceptable type implements a variable long parameter list function and uses the macros provided in Stdarg.h (not discussed here Varargs.h).
For example, we want to implement a simple my_printf:

2. It only accepts "%d" by the integer output, "%c" by character output, "%" output '% ' itself
