Struct Arrays

An array can store several struct values of the same type.

struct_arrays.c

#include <stdio.h>

struct Score {
    int id;
    int points;
};

int main(void) {
    struct Score scores[3] = {{1, 10}, {2, 20}, {3, 30}};
    int index = ;
    int result = scores[index].points;

    printf("points=%d\n", result);
    return 0;
}

#include <stdio.h>

struct Score {
    int id;
    int points;
};

int main(void) {
    struct Score scores[3] = {{1, 10}, {2, 20}, {3, 30}};
    int index = ;
    int result = scores[index].points;

    printf("points=%d\n", result);
    return 0;
}

#include <stdio.h>

struct Score {
    int id;
    int points;
};

int main(void) {
    struct Score scores[3] = {{1, 10}, {2, 20}, {3, 30}};
    int index = ;
    int result = scores[index].points;

    printf("points=%d\n", result);
    return 0;
}

array of structs `scores[index]` selects one struct value from the array.

field after index Use `scores[index].points` to read a field from the selected element.
