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.
