In C++, the auto keyword is used for type inference, which means the compiler automatically deduces the variable's type from its initializer. It’s incredibly handy when dealing with complex types or simply to make your code cleaner.
Pointer = next(Pointer, 1);
Pointer = std::next(Pointer, 1);
++Pointer;
Think of an iterator as a pointer-like object that lets you access and traverse elements of a container. It abstracts away the underlying structure, making your code flexible and reusable.
The keyword
do
in C++ is most commonly seen as part of the do...while
loop—a control structure that executes code at least once before checking a condition. It's great when you want to ensure a block of code runs before validating any exit condition.do {
// Code to execute
} while (condition);
++count: increments count before its value is used
count++: increments count after its value is used
In C++,
.size()
is a method used to retrieve the number of elements in a container from the Standard Template Library (STL). It’s simple but powerful when you need to know the container’s current size.std::vector<int> scores = {1, 2, 3, 4, 5};
I declared and initialized a std::vector<int> named scores with the values {1, 2, 3, 4, 5}
std::cout << "First score: " << scores[0] << std::endl;
scores.push_back(6);
std::cout << "Total scores: " << scores.size() << std::endl;
