Question

C语言输入一个5位的整数 求出各最大和最小的数在第几位并打印输出 求出偶数的个数和奇数的个数并打印输

Answer 1

main ()
{
long int a;
int b,c,d,e,f;
scanf("%ld",&a);
while(a>=1&&a<=99999)
{
if(a/10000>=1&&a/10000<10)
{
printf("this is 5 steps\n");
b=a/10000;
c=(int)((a-b*10000)/1000);
d=(int)((a-b*10000-c*1000)/100);
e=(int)((a-b*10000-c*1000-d*100)/10);
f=a-b*10000-c*1000-d*100-e*10;
printf("b=%d c=%d d=%d e=%d f=%d",b,c,d,e,f);break;}
else if(a/1000>=1&&a/1000<10)
{
printf("this is 4 steps\n");
b=(int)(a/1000);
c=(int)((a-b*1000)/100);
d=(int)((a-b*1000-c*100)/10);
e=a-b*1000-c*100-d*10;
printf("b=%d c=%d d=%d e=%d",b,c,d,e); break; }
else if(a/100>=1&&a/100<10)
{ printf("this is 3 steps\n");
b=(int)(a/100);
c=(int)((a-b*100)/10);
d= a-b*100-c*10;
printf("b=%d c=%d d=%d",b,c,d); break; }
else if(a/10>=1&&a/10<10)
{ printf("this is 2 steps\n");
b=(int)(a/10);
c=a-b*10;
printf("b=%d c=%d",b,c); break; }
else if(a>=1&&a<10)
{ printf("this is 1 step\n");
printf("a=%d",a); break; }
}
getch();

}
这样就可以了。注意if 和else if 的区别
