C Structures

Group related data with struct.

❮ Previous Next ❯

A struct groups variables of different types under one name.

Define: struct Student { char name[30]; int marks; };
Access members with a dot: s.marks.
Through a pointer, use an arrow: p->marks.
typedef creates a shorter type name.

Key Takeaways: C Structures

Mastering C Structures helps you write clean and reliable C code. Follow standard conventions, test edge cases, and keep logic simple. Try running the code example below and complete the exercises to build confidence.

C Structures Code Example

#include <stdio.h>
#include <string.h>

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

void bonus(Student *s) { s->marks += 5; }

int main() {
    Student list[] = {{"Ali", 81}, {"Sara", 94}};
    strcpy(list[0].name, "Ali Khan");
    bonus(&list[0]);

    for (int i = 0; i < 2; i++) {
        printf("%s: %d\n", list[i].name, list[i].marks);
    }
    return 0;
}
