求猪！！！c语言转换~~~

#include <stdio.h>
void main()
{
int i=2,s=0;

begin: if (i%2==0) s+=i;
i++;
if (i<=100) goto begin;
printf("%d",s);
}

main()
{
int i,sum=0;
i=2;
loop: if (i<=100)
{
sum=sum+i;
i=i+2;
goto loop;
}
printf("%d",sum);
}

main()
{int i,sum=o;
i=2;
loop:if(i<=100)
{sum=sum+i;
i=i+2;
goto loop;}
printf("%d\n',sum);
}
