    for (i = 0; i < n; i++)
        printf("%d     %-15s        %-d          %-5d     %-5d
        %d/%d/%d \n", i + 1, item[i].name, item[i].code, item[i].qty,
        item[i].price, item[i].mfg.day, item[i].mfg.month,
        item[i].mfg.year);
    printf("---------------------------------------------------------
    ---------\n");
}

Program Explanation

In this C program, integer variables are stored in the structure and the variable item[50] is used to access the integer variable stored in the structure. We are reading the number of variables using ‘n’ variable. The fflush(stdin) function will flush the input buffer of a stream.

Using for loop enter the name of the item using ‘item[i].name’ variable, the code of the item using the ‘item[i].code’ variable, the price of the item using the ‘item[i].price’ variable, and the manufacturing date of the item using ‘item[i].mfg.day’, ‘item[i].mfg.month’, ‘item[i].mfg.year’ variables. Then print the values in a structured way.
