11 for Loop

12. for loop

for (int i = 0; i < 5; i++) {
  cout << i << "\n";
}

The for loop is composed of three statements that manage the logic for the execution if the code block.

for (statement 1; statement 2; statement 3) {
	// ...  code block to be executed
}

1. The first statement (int i = 0 ) executes only once at the start of the loop, and before the execution of the code block.
2. The second statement (i < 5) defines the condition in which the code block is executed. If the condition is not met, the loop ends.
3. The third statement (i++) executes on every loop after the code block is executed.
