Join Dan Gookin for an in-depth discussion in this video Working with values and placeholders, part of Learning C (2014).
- A value is typically numeric,…although it doesn't have to be.…In your code you can specify values such as three,…five or even 100,000,000.…The printf function can be used to display…those values providing you know about something…called a place holder.…In this movie, I continue exploration…of the printf function.…I show you how place holders can be used…to display values, not only numbers…but strings and individual characters as well.…To view values in action,…you can use the printf function…but you have to take that function up a notch.…
The printf statement at line five generates outputs…that would have you believe the number 27…was a value but it's not, it's part of a string,…just the characters two and seven.…To specify a value, you need to do two things.…First, you must place a value into the code,…in this case, the number 27.…Second, you must direct the printf function…to display that value.…Edit line five to replace the characters…two and seven with %d.…
In some editors, you may see the %d highlighted,…that's because it's a special symbol…
