(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 < 3for(int i{0}; i<3;++i)// expression:     ++istd::cout<< i;// statement:      std::cout << i;}
