[Dart] 1일차_loop (for/while)

1) for loop

void main() {
  // for loop
  for(int i = 0; i < 10; i++) {
    print(i);
  }
  
  int total = 0;
  
  List<int> numbers = [1, 2, 3, 4, 5, 6];
  
  for(int i=0; i < numbers.length; i++){
    total += numbers[i];
  }
  
  print(total);
  
  total = 0;
  
  for(int number in numbers){
    total += number;
  }
  
  print(total);
}

2) while loop

void main() {
  // while loop
  
  int total = 0;
  
  while(total < 10) {
    total += 1;
    
    if(total == 5){
      break;
    }
  }
  
  print(total);
  
  total = 0;
  
  for(int i = 0; i< 10; i++){
    total += 1;
    if(total ==5){
      break;
    }
  }
  
  print(total);
  
  // do-while은 거의 쓰지 않는다
//   do {
//     total += 1;
//   } while(total < 10);
  
//   print(total);
}

3) break, continue

void main() {
  // while loop
  
  for(int i = 0; i < 10; i++) {
    if(i == 5){
      continue;
    }
    print(i);
  }
}
