Certainly! The log() function in C++ is used to calculate the natural logarithm (base e) of a given number. It takes one argument and returns the logarithm value as a double.
Here's an example code snippet that demonstrates the usage of the log() function:
#include <iostream>
#include <cmath> // Required for the log() function
int main() {
double number = 10.0;
double logarithm = log(number);
std::cout << "Number: " << number << std::endl;
std::cout << "Natural Logarithm: " << logarithm << std::endl;
return 0;
}
In this example, we include the <cmath> header file which provides the log() function. We declare a double variable number and assign it a value of 10.0.
By calling log(number), we calculate the natural logarithm of number. In this case, the natural logarithm of 10 is approximately 2.30259. We store this result in the logarithm variable.
Finally, we print the original number and the natural logarithm using std::cout.
The output will be:
Number: 10
Natural Logarithm: 2.30259
As you can see, the log() function calculates the natural logarithm of a given number in C++.
