main()
{
    int a,b,c,d,e;
    a=8512,b=1369,c=3254,d=8795;
    sum(a,b,c,d,e);
    printf("%d+%d+%d+%d=%d\n",a,b,c,d,e);
}
sum(p,q,r,s,t)
int *p,*q,*r,*s,*t;
{
    *t=*p+*q+*r+*s;
    return(*t);
}

还有这个程序，在Tubro C里面是错的，不知道那里错了请大家帮忙看看
static char a="tianjin";
main()
{
    printf("%s is one city in China.\n",a);
    p1();
    p2();
}
p1()
{
    printf("%s is one of the biggest city",a);
    return;
}
p2()
{
    printf("in the world.\n");
    return;
}
