In C, declaring your enum the first way allows you to use it like so: If you use the second style, you’ll be forced to declare your variable like this: As mentioned by others, this doesn’t make a difference in C++. My guess is that either the person who wrote this is a C programmer … Read more
This is a try using only standard C++. Most of the time I use a combination of std::istringstream and std::getline (which can work to separate words) to get what I want. And if I can I make my config files look like: foo=1,2,3,4 which makes it easy. text file is like this: And you parse … Read more
If you want to do this the C++ way, do it like this: If you need that data in a buffer to modify it or something, do this:
You just try to read an int with cin >> [int variable], and make sure it succeeded. If not, wash, rinse, and repeat: That will work, but will return 12 when given input like 12 a because it will read the 12 and stop at a. If you do not want to just “get as much as you can” and want … Read more
According to the docs at cplusplus.com, The member function returns 0 if all the characters in the compared contents compare equal, a negative value if the first character that does not match compares to less in the object than in the comparing string, and a positive value in the opposite case. So it will sort … Read more
The undefined reference error indicates that the definition of a function/method (i.e constructor here) was not found by the linker. And the reason that adding the following line: fixes the issue, is it brings in the implementation as part of the main.cpp whereas your actual implementation is in StaticObject.cpp. This is an incorrect way to fix this problem. I haven’t used Netbeans … Read more
Mehrdad Afshari’s answer would do the trick, but I found it a bit too verbose for this simple task. Look-up tables can sometimes do wonders: Note that rand generates poor-quality random numbers.
You can use the ncurses library to do this. The downside to this solution is that you won’t be able to use cout for outputting anymore. Be sure to -lncurses when compiling
At least, gcc supports MIPS. A convenient way to try it with small programs could be Godbolt’s Compiler Explorer See this: https://godbolt.org/z/UGzp4r
Try specifying the last argument as ‘\n’ in both getline() functions: instead of
