log base 10 c+_+

To calculate the logarithm of a number c to the base 10 in C++, you can use the log10() function from the <cmath> library. Here are the steps to compute it:

1. Include the <cmath> header at the beginning of your code to use the math-related functions: cpp #include <cmath>

2. Declare a variable c of the desired data type and assign it a value: cpp double c = 100;

3. Use the log10() function to calculate the logarithm of c to the base 10: cpp double result = log10(c);

The log10() function takes the logarithm of c to the base 10 and returns the result. In this case, the result will be stored in the result variable.

1. Print the result: cpp std::cout << "Log base 10 of " << c << " is: " << result << std::endl;

This will output the calculated logarithm value.

Here's the complete example code:

#include <iostream>
#include <cmath>

int main() {
    double c = 100;
    double result = log10(c);

    std::cout << "Log base 10 of " << c << " is: " << result << std::endl;

    return 0;
}

This code will calculate the logarithm of c to the base 10 and print the result.
