Numerical Range / Sum Calculator §

#include <iostream>
#include <cmath>
 
int main()
{
    // caleb b
    // numerical range / sum calculator
 
    int startVal;
    int endVal;
    int sum = 0;
    int product = 1;
 
    std::cout << "Enter a starting value: " << std::endl;

    std::cout << "The product of the numbers between " << startVal << " and " << endVal << " is " << product << std::endl;

Average Calculator §

#include <iostream>
#include <cmath>
 
int main()
{
    // caleb b
    // average calculator
 
    // prompt the user to input their number of classes
    std::cout << "How many classes are you taking? " << std::endl;

    std::cout << "Enter your grades: " << std::endl;
    for(int i = 0; i < numClasses; i++)

        std::cout << "Class " << i + 1 << ": ";
        double grade;
        std::cin >> grade;

    }
    double average = grades / numClasses;
    std::cout << "Your average is: " << average << std::endl;
    return 0;
}
 

100m Race Simulator §

#include <iostream>
#include <cmath>

    bool running = true;
    int totalDistance = 0;

        if (distanceTraveled < 10 || distanceTraveled > 25) {
            std::cout << "Invalid distance. Please enter a distance between 10 and 25 meters." << std::endl;
            continue;
        }
        // if it's valid, add to the total
        totalDistance += distanceTraveled;
        // print the total distance
        std::cout << "The runner has run " << totalDistance << " meters." << std::endl;
