题目：输入3个数a,b,c，按大小顺序输出。 1.程序分析：利用指针方法。 2.程序源代码： /*pointer*/ main() {
int n1,n2,n3;
int *pointer1,*pointer2,*pointer3;
printf(\scanf(\pointer1=&n1; pointer2=&n2; pointer3=&n3;
if(n1>n2) swap(pointer1,pointer2); if(n1>n3) swap(pointer1,pointer3); if(n2>n3) swap(pointer2,pointer3);
printf(\}
swap(p1,p2) int *p1,*p2; {int p;
p=*p1;*p1=*p2;*p2=p; }
