Variables and Output

Declare values and print a formatted message.

#include <iostream>
#include <string>

int main() {
    std::string name = "Mira";
    int score = 128;

    std::cout << name << ": " << score << " points\n";
    return 0;
}

Loop Over a Vector

Medio

Use a range-based loop to total vector values.

#include <iostream>
#include <vector>

int main() {
    std::vector<int> values{4, 8, 15, 16, 23, 42};
    int total = 0;

    for (int value : values) {
        total += value;
    }

    std::cout << total << '\n';
}

Function Overloading

Medio

Define overloads for integer and decimal values.

#include <iostream>

int doubleValue(int value) {
    return value * 2;
}

double doubleValue(double value) {
    return value * 2.0;
}

int main() {
    std::cout << doubleValue(12) << '\n';
    std::cout << doubleValue(2.5) << '\n';
}
