float默认小数点后六位,所以输出97.000000,但是double为啥输出也是97.000000
#include <stdio.h>
int main()
{
char c = 'a';
int n=c; //将c赋值给n
float f=n; //将c赋值给f
double d=f; //将c赋值给d
printf("%d\n",n);
printf("%f\n",f);
printf("%lf\n",d);
return 0;
}
#include <stdio.h>

printf("%d\n",n);
printf("%f\n",f);
printf("%lf\n",d);
return 0;
}
