max in c++ with three elements

Finding the maximum element in C++

To find the maximum element among three elements in C++, you can use the max function from the <algorithm> library. Here are the steps to do it:

1. Include the <algorithm> library at the beginning of your code.
2. Declare three variables to hold the three elements.
3. Use the max function to compare the three elements and store the maximum value in a variable.
4. Print the maximum value.

Here's an example code snippet that demonstrates these steps:

#include <iostream>
#include <algorithm>

int main() {
    int a = 10;
    int b = 20;
    int c = 15;

    int max_value = std::max({a, b, c});

    std::cout << "The maximum value is: " << max_value << std::endl;

    return 0;
}

Explanation of each step:

1. The <algorithm> library is included to use the max function.
2. Three variables a, b, and c are declared and initialized with the respective values.
3. The max function is used with the three elements enclosed in curly braces {} to compare them and find the maximum value. The result is stored in the max_value variable.
4. The maximum value is printed using std::cout.

Please note that this code snippet assumes that you have already defined the values of the three elements (a, b, and c). You can modify the values as per your requirements.
