Array of struct c program

#include <stdio.h>

struct st {

    int a;
    char c;

};

int main()
{

    // Declare an array of 3 structure objects
    struct st st_arr[3];

    // first structure object
    struct st st_obj0;
    st_obj0.a = 0;
    st_obj0.c = 'a';

    //Second structure object
    struct st st_obj1;
    st_obj1.a = 1;
    st_obj1.c = 'b';

    // Third structure object
    struct st st_obj2;
    st_obj2.a = 2;
    st_obj2.c = 'c';

    // Initializing first element of array with first structure object
    st_arr[0] = st_obj0;
    // Initializing second element of array with second structure object
    st_arr[1] = st_obj1;
    // Initializing third element of array with third structure object
    st_arr[2] = st_obj2;

    printf("\n First Element of array has values of a = [%d] and c = [%c]\n",
           st_arr[0].a, st_arr[0].c);
    printf("\n Second Element of array has values of a = [%d] and c = [%c]\n",
           st_arr[1].a, st_arr[1].c);
    printf("\n Third Element of array has values of a = [%d] and c = [%c]\n",
           st_arr[2].a, st_arr[2].c);

    return 0;
}

Output :

First Element of array has values of a = [0] and c = [a]

Second Element of array has values of a = [1] and c = [b]

Third Element of array has values of a = [2] and c = [c]
