Question

Write a C++ program that asks the user for a positive number greater than 1 (does not have to be an integer). Call the sqrt function to return the square root of the number. Do this by including the cmath library. This page gives an example of using this sqrt function and including the cmath library.

Answer 1

#include <iostream>
#include <cmath>
using namespace std;

int main()
{
    int n;
    
    cout<<"Enter positive number: ";
    cin>>n;
    
    cout<<sqrt(n)<<endl;

    return 0;
}
