Thread: Printf buffer

Dear all, look at this:
printf("℅d",3,3);
printf("%d %d");
It prints 333
The first 3 is printed as expected, the second goes to the buffer and is printed instead of the second "%d"
But the third "%d" not referred to any number or buffered data , it prints the third 3, where is this coming from?
Thx

As @laserlight says: undefined behavior.

Tip: If you are using glibc and want to use only one argument, you can do, for example:

Code:

printf( "%1$d -> 0x%1$02x", 3 );

Will print:

Code:

3 -> 0x03
