Grammatically speaking, this is true, but in reality, this is another problem. Character variables are stored in binary numbers, which are stored in physical memory. When using them, first call up this number, and then the system will find the character two accordingly. But now, if you assign the amount of characters to plastic variables and display them in plastic, the displayed result must be a number, not a character, and this number is a number corresponding to ASCII, then your running result must be 97.
