c语言里面这个怎么做出来.吧p1,p2的值调换过来

#include
void main()
{
int i,j,t;
printf("Enter two numbers:\n");
scanf("%d %d",&i,&j);//输入时必须以空格分开两个整数
printf("before:i=%d,j=%d\n",i,j);
t=i;
i=j;
j=t;
printf("after:i=%d,j=%d\n",i,j);
}
再问： 要用到指针运算哦
再答： #include void main() { int i1,i2,*p1,*p2,t; p1=&i1; p2=&i2; printf("Enter two numbers:\n"); scanf("%d %d",p1,p2); printf("before:i1=%d,i2=%d\n",i1,i2); t=*p1; *p1=*p2; *p2=t;提交回答 printf("after:i1=%d,i2=%d\n",i1,i2); }
