Question

In C++ Please,

Write a code fragment that uses a loop to calculate ln (i.e. natural log), from values of ranging from ‘1’ through ‘10’ in steps of ‘1’. Print out in this format:

Ln(1) = 0

Ln(2) = 0.6931

etc.

Answer 1

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

using namespace std;

int main() {
    cout << "Ln(1) = 0" << endl;
    cout << setprecision(4) << fixed;
    for (int i = 2; i <= 10; ++i) {
        cout << "Ln(" << i << ") = " << log(i) << endl;
    }
    return 0;
}
