2-8正确答案：
#include <stdio.h>
int main()
{
char c = 'a';
int n = c; //将c赋值给n
float f = c; //将c赋值给f
double d =c; //将c赋值给d
printf("%d\n",n);
printf("%f\n",f);
printf("%lf\n",d);
return 0;
}
ps:一定要打上那个英文半角符的:
#include <stdio.h>
int main()
{
char c = 'a';
int n = c; //将c赋值给n
float f = c; //将c赋值给f
double d =c; //将c赋值给d
printf("%d\n",n);
printf("%f\n",f);
printf("%lf\n",d);
return 0;
}

定义变量时，英文字母应以单词首字母大写或由下划线分开。例如“学生会”(student union)应写为"StudentUnion"或"student_union".同一个嵌套的指令应对齐，相对是一个Tab的距离（4个空格）
