Aman & Mr.Sharma

Problem:-

On a distant planet far away from Earth lives a boy named Aman.He loves to run everyday.But his running distance is directly affected by how much horlicks his mother mixed in his milk today.If his mother has mixed x grams of horlicks,then Aman will be capable of running 100*x meters at most on that day.
Aman's instructor, Mr.Sharma ,is a very strict yet very caring.Everyday he asks Aman to run around a circle of radius r once.If Aman is able to complete the circle,he would get a toffee.
Note:Take value of pie=22/7.
CONSTRAINTS:
1<=d<10⁵
1<=r<10⁶
1<=x<=10⁴
INPUT:
First line contains d,no. of days Aman goes to his instructor.Next d lines each contain r,radius of circle and x,amount of horlicks.
OUTPUT:
Print total number of toffees Aman would finally have at the end of d days.

solution:-

#include<stdio.h>

void main()

{

     int d,r,x,s=0,i,dis,p;

     scanf("%d",&d);

     for(i=1;i<=d;i++)

     {

        scanf("%d%d",&r,&x);

dis=100*x;

        p=2*(3.142857)*r;

        if(dis>=p)

         s=s+1;

     }

     printf("%d",s);

}
