一个5位数,判断它是不是回文数。即12321是回文数,个位与万位相同,十位与千位相同
#include "stdio.h" #include "conio.h" main( ) { long ge,shi,qian,wan,x; scanf("%ld",&x); wan=x/10000; qian=x%10000/1000; shi=x%100/10; ge=x%10; if(ge==wan&&shi==qian)/*个位等于万位并且十位等于千位*/ printf("this number is a huiwen\n"); else printf("this number is not a huiwen\n"); getch(); }
