- The for loops used to check through a block of code a number of times.
- Statement 1 is executed before the loop (the code block) starts.
- Statement 2 defines the condition for running the loop (the code block).
- Statement 3 is executed each time after the loop (the code block) has been executed.
for (statement 1; statement 2; statement 3) { //code block to be executed }
