program to find sum of two distances measured in feet and inch using function and typedef.

    scanf("%d%d",&var.feet1,&var.inch1);//gets input

printf("total feet=%d and total inch=%d\n",total.total_feet,total.total_inch);//prints output
}

//note: Let's not declare function at the top like we do in functions. If it is then it would not work.

Program to understand typedef for struct.

}access;                         // it is being tag (struct). It has got all property of struct
    access first;                 //variable of tag access. we can also put inside main function.
int main()
{
    printf("enter name\n");
    gets(first.name);            //gets input

    scanf("%d",&first.roll);
    printf("name=%s , address=%s and roll=%d\n",first.name,first.add,first.roll);//displays output.

//note: putting a tag doesnot make any different. We have to use same method as given in above //example.
//Mostly, the tag is unimportant.
