hi all!
what is wrong with this code?
#include <iostream>
#include <cmath>
#include <vector>
using namespace std;

int ragham(double x)
{
    int z=0,num;
    num=int(x);
    for(int i=1;num>0;i++)
    {
        num/=10;
        z=i;
    }
    return z;
}
int main()
{
    vector <long double> a;
    double b,c;
    int j=0,g;
    long double u;
    while(cin>>u)
    {
        a.push_back(u);
        j++;
    }
    for(int i=j-1;i>=0;i--)
    {
        b=sqrt(a[i]);
        c=int((b-int(b))* int(pow(10.0,4)));
        if(c!=0)
        {
            if(ragham(c)==3)
                cout<<int(b)<<".0"<<int((b-int(b))*pow(10.0,4))<<endl;
            else if(ragham(c)==2)
                cout<<int(b)<<".00"<<int((b-int(b))*pow(10.0,4))<<endl;
            else if(ragham(c)==1)
                cout<<int(b)<<".000"<<int((b-int(b))*pow(10.0,4))<<endl;
            else if(ragham(c)==4)
                cout<<int(b)<<'.'<<int((b-int(b))*pow(10.0,4))+1<<endl;
        }
        else cout<<b<<".0000"<<endl;
    }
    return 0;
}

---------------------
according to the code,i think you surely understood that i am a freshman!:)
