Would you write c plus plus program using function for logarithm of number?

Yes, I can write a C++ program that uses a function to calculate the logarithm of a number. The program would include the <cmath> library for the log function, which computes the natural logarithm. Additionally, I can create a custom function to allow the user to specify the base of the logarithm if needed. Here's a simple example:

<code class="language-cpp">#include <iOStream>
#include <cmath>
double customLog(double number, double base) { return log(number) / log(base); }
int main() { double number = 10.0; double base = 2.0; std::cout << "Logarithm of " << number << " to base " << base << " is " << customLog(number, base) << std::endl; return 0; }
