The struct type

Can be seen as a combination of other data types (including other struct)

Is similar to classes in OOP languages

Initializing and accessing. 

int main(int argc, char const *argv[])
{
    struct example {
        int number;
        char name[32];
    };

    struct example example1;
    strcpy(example1.name,"Juan Pablo");
    example1.number = 7;

    struct example example2 = {
        8,
        "Pablo Juan"
    };

    printf("%s, number: %d\n", example1.name, example1.number);
    printf("%s, number: %d", example2.name, example2.number);
   
    return 0;
}

The code above prints

Juan Pablo, number: 7
Pablo Juan, number: 8

And shows both ways of initializing a struct

Note that in C, the = operator doesn’t assign value to strings, and strcpy should be used.

In Functions

You can also return structures from functions by defining their return type as a structure type. For instance:

struct example function();
