for loops

In C++, vector<int> is a dynamic array from the Standard Template Library (STL) that stores integers. Unlike regular arrays, vectors can grow or shrink in size during runtime.

for (initialization; condition; update) {

    // Code to execute in each iteration

}

average += laptimes[i];

is equivalent to

average = average + laptimes[i];

average/= laptimes.size();

is equivalent to

average = average / laptimes.size();
