pointless comparison of unsigned integer with zero
    When comparing an unsigned integer to zero, it is often pointless. An unsigned integer is an integral data type that cannot represent negative numbers, making the comparison rendered pointless.
    An unsigned integer is typically used to represent a non-negative value, meaning signs, such as negative numbers and symbols, can not be expressed. If a number is expressed in an unsigned fashion, such as "unsigned int myNumber", the associated value will never be negative - it will based on a certain range of values, expressed as a maximum of the type used. For example, an "unsigned int" can only have values between 0 and 65535.
comparisons    Comparisons with an unsigned integer and zero will always be the same, depending on the current value of the unsigned integer. If the integer holds a value of 0, the comparison will be true; if the integer holds a value higher than 0, the comparison will be false; and if the integer holds any other value, the comparison will still be false. Therefore, since comparisons with an unsigned integer and 0 will always yield the same result, it is pointless
to make such comparison.
    Overall, if you want to make comparisons with an unsigned integer, then any comparison to zero is pointless. The best way to make a useful comparison is to test the number against a range of values or some other related conditions. For example, if you want to test if an unsigned integer is higher than 5, then you should compare that integer to a value of 5 instead of 0. This simple change can make your program a lot more meaningful and accurate.
