Structures in C++ are user-defined data types that allow you to combine different types of data into a single unit. They are useful for organizing related information together.<\/p>\n\n\n\n
A structure ( For example, a student may have:<\/p>\n\n\n\n Instead of creating separate variables, a structure stores them together.<\/p>\n\n\n\n Structures are useful because they:<\/p>\n\n\n\n You can initialize structure values directly.<\/p>\n\n\n\n Structures can also be used in arrays.<\/p>\n\n\n\n A structure can contain another structure.<\/p>\n\n\n\n Structures can also contain functions in C++.<\/p>\n\n\n\n Structures are important because they:<\/p>\n\n\n\n Think of a student ID card:<\/p>\n\n\n\n All related information is stored together, just like a structure.<\/p>\n\n\n\n Structures in C++ are powerful user-defined data types used to group related data together. They improve program organization, readability, and efficiency, making them essential for handling complex information in real-world applications.<\/p>\n\n\nstruct<\/code>) is a collection of variables of different data types grouped under one name.<\/p>\n\n\n\n\n
