What is a for loop?

Loops are useful when you repeatedly want to run the same code, but with a different value each time it runs. There are numerous types of loops, however, “for loops” are used to loop through a block of code a number of times.

The for loop has the following syntax, or format: 

for (statement 1; statement 2; statement 3) {

      // code block to be executed

}

Statement 1 is executed one time before the execution of the code block.

Statement 2 defines the condition for executing the code block.

Statement 3 is executed every time after the code block has been executed.
