再键盘上任意输入一个三位数,要正确的分离个十百位,并显示在屏幕上,用C语言怎么编程序

Answer 1

#include "stdio.h"
int main()
{
int x,a,b,c;
printf("请输入一个三位数：\n");
scanf("%d",&x);
if(x>99&&x<10000)
{
a=(int)x/100;/*求百位*/
b=(int)(x-100*a)/10;/*求十位*/
c=(int)(x-100*a-10*b);/*求个位*/
printf("这三位分别为：%d %d %d\n",a,b,c);
}
else
printf("输入有误！");
system("pause");
return 0;
}

Answer 2

#include<iostream.h>
void main()
{
int a,b,c,d;
cout<<"请输入一个数:";
cin>>a;
if(a>=100 && a<1000)
{
b=a/100;
c=a%100/10;
d=a%10;
cout<<"百位"<<b<<",十位"<<c<<",个位"<<d<<endl;
}
else
cout<<"不是三位数!"<<endl;

}

Answer 3

在tc2.0下调试通过：
# include "stdio.h"
main()
{
int x,y;
int i,a[5];
printf("\nInput a number(100-999).\n");
scanf("%d",&x);
if((x<100)||(x>999))
{
printf("This data is error!");
exit(0);
}
for(i=0;i<3;++i)
{
a[i]=x%10;
x=x/10;
}

printf("units place digit is: %d\n",a[0]);
printf("tens place digit is: %d\n",a[1]);
printf("hundreds place digit is: %d\n",a[2]);
}

Answer 4

来了来了
#include<stdio.h>
int main()
{    int num;
int g,s,b;
printf("输入一个三位数的整数\n");
scanf("%d",&num);
{if(num<0)num=num*(-1);}
printf("%d \n",num);
g=num%10;
num=num/10;
s=num%10;
num=num/10;
b=num%10;
printf("g=%d s=%d b=%d \n",g,s,b); 
  return 0;
}
