C语言程序设计，输入一个四位正整数，将它们倒排输出的算法如下：
#include
#include
int main()
{
int oldnum;
int newnum=0;
int temp;
printf("please input number\n");
scanf("%d",&oldnum);
printf("the old number is %d\n",oldnum);
while (oldnum !=0)
{
newnum = newnum*10+oldnum%10;
oldnum = oldnum/10;
}
printf("the change number is %d",newnum);
getch();
return 0;
};
