功能是计算：如果x被10整除，则y和z的值都等于x，否则y=2*x z=3*x

#include <stdio.h>

 int main(void)

 {

    int x,y,z;           

   printf("Enter x:\n");  

    scanf("%d",&x);      

    if(x%10==0)

    {

        y=x;

        z=x;

         

    }        

    else

     {

        y=x*2;           

        z=x*3; 

     }

    printf("y=%d\nz=%d",y,z);

   return 0; 

 }
