Question

我用 C语言写了一个程序 是用宏判断该字母是否为小写字母的程序

#include<stdio.h>
#define ISLOWER(c) (c>='a')&&(c<='z');
int main(void)
{
int c,a;
printf("Enter c:\n");
scanf("%d",&c);
a=ISLOWER(c)
printf("%d",a);
if(a)
printf("是\n");
else
printf("不是\n");
return 0;
}
求错在哪里啊· 各位仁兄 帮忙看看

Answer 1

#include<stdio.h>
#define ISLOWER(c) ((c>='a')&&(c<='z')) //宏定义不用加分号
int main(void)
{
int a;
char c; //判断字母怎么能用整型呢
printf("Enter c:\n");
scanf("%c",&c);
a=ISLOWER(c);
printf("%d ",a);
if(a)
printf("yes\n");
else
printf("no\n");
return 0;
}

Answer 2

#include<stdio.h>
#define ISLOWER(c) (c>='a')&&(c<='z');
int main(void)
{
char c,a;
printf("Enter c:\n");
scanf("%c",&c); //下面应该是c
printf("%c",c); //同上
a=ISLOWER(c);
if(a)
printf("是\n");
else
printf("不是\n");
return 0;
}
