Practical C Programming

How it works...

When you define a variable of the type structure, that variable can access members of the structure in the following format:

structurevariable.structuremember

You can see a period (.) between the structure variable and the structure member. This period (.) is also known as a dot operator, or member access operator. The following example will make it clearer:

struct cart mycart;mycart.orderno

In the preceding code, you can see that mycart is defined as a structure variable of the cart structure. Now, the mycart structure variable can access the orderno member by making the member access operator (.).

You can also define a pointer to a structure. The following statement defines ptrcart as a pointer to the cart structure.
