This is my code.


#include <iostream>
#include <cmath>
#include <iomanip>

using namespace std;

int main()
{
    long double a;
    cin >> a;
    cout << fixed << setprecision(4) << sqrt(a) << endl;
    return 0;
}

In my opinion the problem is that the user should be able to insert a set of numbers, while in your code you can only give 1 value in input.

as i known you can insert the code "main()" on the line of "return 0;"

the wrong is your data type try to store the double side alone and the integar alone and then calculate them into output :D

like
long long int_side = sqrt(a);

double float_side = sqrt(a)-int_side;

cout << int_side+float_side ;

You also have to print result in reverse order. Square root of number you read last should be displayed first.
