Learning how to use typedef and struct

typedef_and_struct.c

#include <stdio.h>

// create a typedef
// create a variable using your "new" data type

// using typedef we can create an alias to a
// common data type to give context

typedef char TEXT;


// by using typedef
// we can skip the struct keyword
// when declaring variables of our
// struct's name which is SUPERHERO
// notice on line 28 we don't declare it
// struct SUPERHERO a we just declare
// SUPERHERO a
typedef struct
{
    // notice the star indicating
    // this data type is a pointer
    // which is what we need for strings (char * or char mytext[])
    TEXT * name;
    TEXT * ability;
}SUPERHERO;

int main(void)
{
    SUPERHERO a;

    a.name = "superman";
    a.ability = "I can fly";

    printf("I am %s and %s\n", a.name, a.ability);


    SUPERHERO b;

    b.name = "batman";
    b.ability = "I'm rich";

    printf("I am %s and %s\n", b.name, b.ability);

    return 0;
