Study Notes

The Purpose of For Loops

The purpose of a for loop is to execute a block of code repeatedly for a specified number of iterations.

For Loop Execution

The initialization section of a for loop is executed only once, at the beginning of the loop.
A for loop terminates when the conditional test fails, i.e., when the condition is false.
The conditional test is performed at the beginning of each iteration, before the code block is executed.
