C++输入字母后输出结果均为0

Question

代码要求判断输入的是否是字母

#include <stdio.h>

int main()
{
char c;

printf("Please enter a character ");
scanf("%d", &c);

((c >= 'a' && c <= 'z') || (c >= 'A' && c <= 'Z')) && printf("The character you entered is %d,it is an alphabet.", c);
((c >= 'a' && c <= 'z') || (c >= 'A' && c <= 'Z')) || printf("The character you entered is %d,it isn't an alphabet.", c);

return 0;
}

只要输入字母就会显示 The character you entered is 0.

课上还没讲解字符类型相关的点，我自己完全不清楚怎么解决。

还请各位指点

Answer 1

scanf("%d", &c);
改成 scanf("%c", &c); char类型 用%c接收 ，%d只能接收整形
