Structure And Function in C++
- Structure is a collection of variables under a single variable.
- Structure variables can be passed to a function and returned in a similar way as normal argument.
- A function is a group of statements that together perform a task.
- Every C++ program has at least one function, which is main(), and all the most trivial programs can define additional functions. You can divide up your code into separate functions.

Passing structure to function in C++
- A structure variable can be passed to a function in similar way as normal argument.
- When an element of a structure is passed to a function, you are actually passing the values of that element to the function. Therefore, it is just like passing a simple variable (unless, of course, that element is complex such as an array of character). Consider this example:
Example 1: C++ Structure and Function
- In this program, user is asked to enter the name, age and salary of a Person inside main() function.
- Then, the structure variable p is to passed to a function using.
- The return type of displayData() is void and a single argument of type structure Person is passed.
- Then the members of structure p are displayed from this function.
