#include <stdio.h>
main()
{ float a,b,x,y,y1,T,h,k;
int i,j,l;
printf("please enter how many times \nyou want to changge the value of T and k \n"); /*??????T?K???*/
scanf("%d",&j);
for(i=1;i<=j;i++)
{
printf("please enter k\n");/*??K?*/
scanf("%d",&k);
printf("please enter T\n");/*??T?*/
scanf("%d",&T);
h=T/10;
a=T/(T+h);b=k*(1-a);
y1=y=0;
for(l=1;l<=20;l++)
{x=5;
y=a*y1+b*x;
printf("%d,%f\n",l,y);
y1=y;
}
}
}
