    // Calculate the size of long int data type
    printf("The size of long int: %ld bytes\n", sizeof(long int));

    // Calculate the size of unsigned long int data type
    printf("The size of unsigned long int: %ld bytes\n", sizeof(unsigned long int));

    // Calculate the size of long long int data type
    printf("The size of long long int: %ld bytes\n", sizeof(long long int));

    // Calculate the size of unsigned long long int data type
