First, it usually does not matter that much in practice. Most hash functions are “good enough”. But if you really care, you should know that it is a research subject by itself. There are thousand of papers about that. You can still get a PhD today by studying & designing hashing algorithms. Your second hash … Read more
word_array[0] is a char, whereas word1 is a char *. Your character is not able to hold an address. An array of strings might look like it: If you rather want an array of pointers to your strings: And then: Maybe you should read this.
The method works if you provide an array. The output of is (the number after @ is almost always different) Please tell us the return type of Employee.getSelectCancel()
In C++11, use std::stoi as: std::string s = “10”; int i = std::stoi(s); Note that std::stoi will throw exception of type std::invalid_argument if the conversion cannot be performed, or std::out_of_range if the conversion results in overflow(i.e when the string value is too big for int type). You can use std::stol or std:stoll though in case int seems too small for the input string. In C++03/98, any of the following can be … Read more
Ok. I found a program buried deep in other files from the beginning of the year that does what I want. I can’t really comment on the suggestions offered because I’m not an experienced spim or low level programmer.Here it is:
Here’s an alternative since you don’t like the cast to int:
I’ve never heard of a best practice for this specific question. However, one best practice in general is to use the simplest solution that solves the problem. In this case the array-style access (or c-style if you want to call it that) is the simplest way to iterate while having the index value available. So … Read more
Use , to separate strings and variables while printing: , in print function separates the items by a single space: or better use string formatting: String formatting is much more powerful and allows you to do some other things as well, like padding, fill, alignment, width, set precision, etc. Demo:
As further comment, you should be aware of this term in the equals contract: From Object.equals(Object): For any non-null reference value x, x.equals(null) should return false. The way to compare with null is to use x == null and x != null. Moreover, x.field and x.method() throws NullPointerException if x == null.
Boost includes a handy algorithm for this:
