Question

c语言编程题，求大佬

Answer 1

这种题目熟悉输入函数，简单的函数加减乘除，进度控制。
double a,b,c,avg;
scanf("%f%f%f",&a,&b,&c);
avg = (a+b+c)/3.0;
avg = avg*100;
if(avg%10 >= 5.0)
{
avg +=10;
}

avg = avg /100.0;
printf("%0.1f\n",avg);

Answer 2

#include<stdio.h>
void main(){
double x,y,z,ave;
printf("请输入三个数:");
scanf("%lf %lf %lf",&x,&y,&z);
ave=(x+y+z)%3.0;
ave= (int)(ave*10+0.5)/10;
printf("ave=%.1f\n",ave);
}
