Software Tools
Gbogbo ọrọ náà
Every time you type a name, a date or a price into a computer there is a chance of getting it wrong, and a single wrong character can send a bill to the wrong person or break a calculation. Software tools are the built-in helpers that catch those slips for you: the spell checker that questions an unfamiliar word, the grammar checker that flags an odd sentence, and the validation rules that refuse data which is simply not reasonable. Used well, they turn careless errors into rare ones.
In this lesson you will learn exactly what each tool can and cannot do. You will see why a spell checker happily accepts a real word used in the wrong place, and you will learn the five validation checks the Cambridge syllabus expects you to name and apply, from a range check on a temperature to a format check on a date. Knowing the limits of these tools is what separates a careful operator from one who trusts the machine too far.
