i m getting WA!!!.
plz Help.

#include<cstdio>
#include<cmath>
int main()
{
int T,L;
double redArea,greenArea;
scanf("%d",&T);
while(T--)
{
scanf("%d",&L);
int r=L/5;
int W = L*6/10;
redArea=acos(-1)*pow(r,2);
greenArea=L*W-redArea;
printf("%.2lf %.2lf\n",redArea,greenArea);
}

return 0;
}

Think about what your code is doing when L is not a multiple of 5.

Use double variables, instead of floats. Check for example:

Input

Code: Select all

2
1000
775

Output

Code: Select all

i m getting WA!!!.
plz Help.

#include<stdio.h>
#include<math.h>
#define PI acos(-1)
int main()
{
double a,r;
unsigned n,i,l;
scanf("%u",&n);
for(i=1;i<=n;i++)
{
scanf("%u",&l);
r=PI*(l/5)*(l/5);
a=(6*(l*l))/10;
printf("%.2lf\t%.2lf\n",r,a-r);
}
return 0;

I just can't see the problem of this code ....can you

Code: Select all

Got the solution

#include <math.h>
try using M_PI instead of your pi constant

    {
        for(i=1;i<=test;i++)
        {
            scanf("%f",&l);
            w = 0.6*l;
            r = l/5;
            printf("%.2f %.2f\n",PI*r*r,(l*w)-(PI*r*r));
        }
        }
    return 0;
