JAVA实现随便输入一个四位数判断是平年还是闰年,第一位不能为零怎么简便一点

#includeusingnamespacestd;voidmain(){inta[4];cout再问：还是有好几个错误再答：#includeusingnamespacestd;voidmain(

inti=2123;intone,two,three,four;one=i%10;//各位two=(i/10)%10;//十位three=(i/100)%10;//百位four=(i/1000)%10

#includevoidmain(){inti,j,k,m,n;printf("inputanumber:\n");scanf("%d",&n);i=n/1000;j=(n%1000)/100;k=(

创建两个text控件和一个command按钮控件再输入以下代码PrivateSubCommand1_Click()Fori=1ToLen(Text1.Text)a=Mid(Text1.Text,i,1

#includeintmain(){intn,m;scanf("%d",&n);m=0;while(n>0){m=m*10+n%10;n/=10;}printf("%d\n",m);return0;}

楼上说没错,while(X)是先进行X判断然后再执行{语句体},而do..while则是先执行do{语句体},再判断while(X),这样会导致do..while比while执行语句体的次数多一次再问

作为字符串形式读入比用整形读入好处理,而且数的位数不受限制（整型有数值超界问题）#includevoidmain(){chars[80];//最长80位数字inti,L;printf("pleasei
