电脑高手帮忙写低级C语言程序。

#include <stdio.h>

void main()
{
int a, b, c, d;
int max1, max2;
printf("请输入四个数!\n");
scanf("%f %f %f %f", &a, &b, &c, &d);
max1 = (a>b)?a:b;
max2 = (c>d)?c:d;
printf("最大的数是：%f\n", (max1>max2)?max1:max2);
}

#include <stdio.h>

void main()
{
int a, b, c;
int max, min,mid;
printf("请输入三个数!\n");
scanf("%f %f %f", &a, &b, &c);
max = a>b?a:b;
max = max>c?max:c;
min = a<b?a:b;
min = min<c?min:c;
mid= a+b+c-max-min;
printf("%f\t%f\t%f\n" ,max,mid,min);

}

1.
#include<stdio.h>
main()
{
int a[4],i,max;
for(i=0;i<4;i++)
scanf("%d",&a[i]);
max=a[0];
for(i=1;i<4;i++)
if(max<a[i]) max=a[
