Adequate facilities for defining data types and structures aids readability. E.g. Early FORTRAN had no record/struct construct, so the "fields" of an "object" could not be encapsulated within a single structure (that could be referred to by one name). Later this semester, we will look at various categories of data types and look at design issues and design choices of common languages.. Records are among the simplest, most basic data structures.
2. Write the same program in the same language without using structs.
3. Submit the code and output of both programs with a brief (at least 100 words) on which program better meets readability and why (or if you believe both are equal that's ok too; be sure to justify your answer).
#include
#include
// define a struct to store student information
struct student{
// char array to store first name
char fname[20];
// char array to store last name
char lname[20];
// store age of the student
int age;
float GPA;
char grade_level[20];
};
int main()
{
int n, i;
printf("Enter the size of array ");
// scan n
scanf("%d",&n);
printf(" ");
// dynamically create an array of size n
struct student *arr = (struct student *)malloc(n * sizeof(struct student));
for( i = 0 ; i < n ; i++ )
{
printf("For student %d ... ", i + 1);
printf("Enter the name of the student ");
// scan the name of the student
scanf("%s%s",&arr[i].fname,&arr[i].lname);
printf("Enter the age of the student ");
// scan the name of the student
scanf("%d",&arr[i].age);
printf("Enter the GPA of the student ");
// scan the name of the student
scanf("%f",&arr[i].GPA);
printf("Enter the grade level of the student ");
// scan the name of the student
scanf("%s",&arr[i].grade_level);
printf(" ");
}
printf(" Student Record ... ");
for( i = 0 ; i < n ; i++ )
{
printf("For student %d ... ", i + 1);
printf("Name : %s %s ",arr[i].fname,arr[i].lname);
printf("Age : %d ",arr[i].age);
printf("GPA : %f ",arr[i].GPA);
printf("Grade Level : %s ",arr[i].grade_level);
printf(" ");
}
return 0;
