{
// The following 'for' loop statement:
// 1. (init-statement) Declares an integer named 'i' and initializes it with value '0'.
// 2. (condition) Checks if i is less than 3 and if not, ends the loop execution.
// 3. (statement) Writes out a current value of the integer 'i' to the stdout.
// 4. (expression) Pre-increments the integer 'i' (increases its value by 1).
// 5. Returns to the point 2 (condition).
// init-statement: int i{0};
// condition: i < 3
for (int i{0}; i < 3; ++i) // expression: ++i
