求高手帮我编写一个c程序,输入一个字符,如果该字符是英文字母,则打印出该字母的ASCII码,要求可以输入任意

#include <stdio.h>

int main(void)
{
char ch;

printf("please input a character: ");
scanf("%c", &ch);
if ((ch >= 'a' && ch <= 'z') || (ch >= 'A') && (ch <= 'Z'))
printf("The ASSII code of this character is:%d.\n", ch);
else
printf("This character is not a letter.");
return 0;
