请问下面一道编程题怎么做：编写一个c程序，输入abc三个值，输出其中最大的。

Question

初学者，愚钝，望高人指点。

Answer 1

#include <stdio.h>

int main()
{
int a,b,c;
scanf("%d %d %d",&a,&b,&c);
if (a>b && a>c)
printf("%d\n",a);

if (b>a && b>c)
printf("%d\n",b);

if (c>a && c>b)
printf("%d\n",c);

return 1;
}

Answer 2

#include <stdio.h>

int main( )
{
bool in = true;
int i, a, maxn, minn;
for ( i = 0; i < 3; i++ )
{
scanf("%d", &a);
if ( in )
{
maxn = minn = a;
in = false;
}
if ( maxn < a ) maxn = a;
if ( minn > a ) minn = a;
}
printf("Max = %d\n", maxn);
return 0;
}

Answer 3

{
int a,b,c,max;
scanf("%d%d%d",&a,&b,&c);
max=(a>b?a:b)>c?(a>b?a:b):c;//先将a,b作比较选取最大的跟c作比较选出最大的把值给予max
printf("%d",&max)
}

Answer 4

#include<stdio.h>
main()
{
int x,y,z,t;
scanf("%d%d%d",&x,&y,&z);
if (x>y)
{t=x;x=y;y=t;} /*交换x,y的值*/
if(x>z)
{t=z;z=x;x=t;}/*交换x,z的值*/
if(y>z)
{t=y;y=z;z=t;}/*交换z,y的值*/
printf("the big: %d\n",z);
}

Answer 5

#include <stdio.h>
main()
{int a,b,c,max1;
scanf("%d%d%d",&a,&b,&c);
max1=a>b?a:b;
printf("%d",max1>c?max1:c);
}
