- Programs work fine with immediate values,…but often times you don't know what a value is.…Say the value comes from input, the user types it,…or it's read from a file or the Internet.…To store such values you need…a specific cubby-hole or container.…In programming that container is known as a variable.…In this movie I introduce you…to the concept of the variable.…It's a container into which you can store values,…values that are unknown or values that can change.…You'll see how to declare a variable in the C language…and how a variable is used in the code.…
A variable is a container for a value.…Because C deals with different types of values…a variable must be declared as a specific type…and it's given a name, a name that's used in the code.…In C the variable type matches the variable's content,…the type of value being stored.…Integer variables can hold only…integer values, or whole numbers.…Float variables hold floating-point values,…which are very large numbers, very small numbers,…or numbers with a fractional part like 2.1.…
