Learn C++

What you will practise

Explore C++ through types, functions and objects. Then learn standard containers and resource management.

• Write functions and classes.
• Use standard library containers.
• Understand references and resource ownership.

Before you start: Basic algorithmic thinking helps; the first exercises introduce essential syntax.

A first example to understand

#include <iostream>
#include <vector>
int main() {
    std::vector<int> values{2, 4, 6};
    int total = 0;
    for (int value : values) total += value;
    std::cout << total << "\n";
}

std::vector stores the numbers. The loop visits their values without a manual index. std::cout prints the sum, 12.

Try it: Add a value with values.push_back(8) before the loop, then check the sum.
