How to make every first letter on my iPhone a capital?

I've seen people's text like this (FOR EXAMPLE) "Hi How Are You? I'm Good Thank you!" I want to try it out in my iPhone? How can I get it? Is it a setting? *Iphone 5 iOS 7

Go to settings, the click general, scroll down and click ' keyboard ' , and make sure ' auto capitalization' is on

They can be bothered to press the Shift key (the arrow) when they write words.

There's a arrow next to the letters on the left side of the key pad if you push it once it will make the first letter a capital if you push it twice it will cause all letters to be capital the third time it will put all back to small letters

You'd have to make the 1st letter capitalized on your own. There's no automatic method for it.

There isn't any option that will capitalize the first letter of every word.
