Learning about structure
We learned about arrays previously. An array holds elements of the same type of data. Say, an integer type of array holds only integers, or a character type of array holds only characters. But a structure is something that can hold different types of data together. To define a structure in C, we can say that a structure is a collection of variables of different data types.
Let's say we want to store information about a person, such as their name, PhoneNum, sex, and salary. All this information is not of the same type. name is a string, PhoneNum is an integer, sex can be defined by a character, and salary is a double number. So, defining one array to store them is not possible. We need to know something else that can hold multiple types of variables. To make the problem even complex, say we want to store information about multiple people.
Can you visualize how messy and long the code we will have to write will be if we want to work with an ordinary array? Well, we will...
