/* sqrt example */
#include <stdio.h>
#include <math.h>

int main ()
{
double param, result;
param = 1024.0;
result = sqrt (param);
printf ("sqrt(%lf) = %lf\n", param, result );
return 0;
}
Output:

sqrt(1024.000000) = 32.000000

include <cmath>
#include <iostream>
int main()
{
int a;
std::cout << "enter a: ";
std::cin >> a;

std::cout << std::sqrt(double(a)) << std::endl;
}

there is a c++ library function called sqrt(<input value>) that you can use for this.
