int？ Major (Invalid) {

Dragon? x = 1；

printf("%d？ %02d\n "，x，x)；

Return? 0;

The output is 10 1. It should be noted here that "%02d" means that the output width of two characters is aligned to the right, and it is filled with 0 when it is insufficient. Therefore, it is invalid to write only 0 without writing the occupancy index 2. When the actual data is equal to or exceeds the occupancy index, 0 will not be added. Such as printf("%02d\n ",123); The output is 123, printf ("%0 10d \ n ",123); The output is 0000000 123, etc.
