Char-type variables are essentially int-type, and when the output is %c, characters are displayed.

The output as %d is that it corresponds to ascii~

The following is the verification code:

# Contains? & ltstdio.h & gt

int？ Mainly? ()

{

Charles? a；

Answer? =? 67;

printf("char？ Answer? =? %c\nascii？ Answer? =? %d\n ",one? a)；

Return? 0;

}
