Typedef in C

In C programming, "typedef" is a keyword that allows you to create an alias or synonym for an existing data type. This can make the code more readable and maintainable by giving a more meaningful name to a complex or obscure data type.
   Syntax :
        typedef data_type new_name ;

For example, you can use typedef to create an alias for the "int" data type, like this:
   Example :
        typedef int INTEGER ;

With this definition, you can use "INTEGER" in place of "int" throughout your code.

    printf("\nAge         : %d",o.age);
    printf("\nPercent     : %f",o.per);
    return 0;
