Structures and Custom Types

Using struct for domain modeling

Structures let you group related fields under one custom type. They are key for representing records like students, employees, and products.

#include <stdio.h>

struct Student {
    char name[30];
    int grade;
    float marks;
};

int main(void) {
    struct Student s = {"Ishita", 12, 91.5f};
    printf("%s scored %.1f\n", s.name, s.marks);
    return 0;
}

typedef and nested structs

• typedef improves readability for custom types.
• Structs can contain other structs.
• Combine structs with pointers for dynamic data models.
