C++ Third angle of a Triangle

To find the third angle of a triangle in C++, you can use the formula:

third_angle = 180 - (first_angle + second_angle)

Here is an example code snippet that demonstrates how to calculate the third angle of a triangle in C++:

#include <iostream>

int main() {
    // Input the first and second angles of the triangle
    float first_angle, second_angle;
    std::cout << "Enter the first angle: ";
    std::cin >> first_angle;
    std::cout << "Enter the second angle: ";
    std::cin >> second_angle;

    // Calculate the third angle
    float third_angle = 180 - (first_angle + second_angle);

    // Output the result
    std::cout << "The third angle is: " << third_angle << std::endl;

    return 0;
}

In this code, we first declare the variables first_angle and second_angle to store the input values for the first and second angles of the triangle. We then prompt the user to enter these values using the std::cin statement.

Next, we calculate the third angle using the formula third_angle = 180 - (first_angle + second_angle). The result is stored in the variable third_angle.

Finally, we output the value of the third angle using the std::cout statement. The std::endl manipulator is used to insert a new line after the output.

Remember to include the <iostream> header to use the input/output stream objects (std::cin and std::cout) in C++.
