We’re back with another Coding Boot Camp 2022 recap. After learning everything about the If statements and how they can be effectively used in any Windows application development. We are going to take a deeper look at the so-called For-loops. In this session, we will be introduced to the idea of iteration. Generally, in programming, is the process where a set of instructions or statements is executed repeatedly for a specified number of times or until a condition is met. These iterations are commonly known as the loops. In this video taken from the recently concluded Coding Boot Camp 2022, Gerhard Visagie will teach us everything about for-loops and will demonstrate how they work in Delphi.

Understanding for loops and its core function

The For loop is used to repeat a section of code known number of times. Like all loops, the “For loops” execute blocks of code over and over again. The video, however, will not just show how this particular type of loop works but it will also demonstrate how it can tidy up your code by deleting a bunch of duplicate statements. The For Loops will rely on three values. First is the so-called Counter Variable that will keep track of every repetition the loop is doing. This is followed by the low and high values. The low value is where the loop must start while the high value is where the loop must end.

Gerhard will also demonstrate how to reverse a For loop in which results are displayed in descending order. We will also get to see how to loop with a range of characters with a for-loop. In addition to that, the video will also introduce us to other types of loops including the Nested For Loops, While Loops, and Repeat/Until Loops. Each comes with samples to help us understand the core feature of for loops better.
