    char charvar;


    // sizeof is used to find the size of a variable

     printf("Size of char: %zu byte\n", sizeof(charvar));

    printf("Size of int: %zu bytes\n", sizeof(intvar));

    printf("Size of double: %zu bytes\n", sizeof(doublevar));

    printf("Size of float: %zu bytes\n", sizeof(floatvar));
