When you know exactly how many times you want to loop through a block of
code, use the for
loop instead of a while
loop:
for (statement 1; statement 2; statement 3) {
// code block to be executed
}
The example below will print the numbers 0 to 4:
Example explained
Statement 1 sets a variable before the loop starts (int i = 0).
Statement 2 defines the condition for the loop to run (i must be less than 5). If the condition is true, the loop will start over again, if it is false, the loop will end.
Statement 3 increases a value (i++) each time the code block in the loop has been executed.
This example will only print even values between 0 and 10:
