I agree with @ravi but I some notes for you: If you don’t know how many integers are in the file and the file contains only integers, you can do this: You need to #include<vector> for this. it would be better if you read how many integers are in the file and then use loop to read them: Note: I … Read more
There are a couple of possibilities. One I like uses a stringstream as a go-between: Now the contents of “file.txt” are available in a string as buffer.str(). Another possibility (though I certainly don’t like it as well) is much more like your original: Officially, this isn’t required to work under the C++98 or 03 standard (string … Read more
You need to multiply your Model matrix. Because that is where model position, scaling and rotation should be (that’s why it’s called the model matrix). All you need to do is (see here) Note that to convert from degrees to radians, use glm::radians(degrees) That takes the Model matrix and applies rotation on top of all the operations that are … Read more
The size of an array is static in C++. You cannot dynamically resize it. That’s what std::vector is for:
For space separated strings, then you can do this: Output: string that have both comma and space Output:
I am using some existing code that someone else has written, and I cannot get it to compile (limited C experience here but I am trying to learn!). utilities.cc Here is the error. The error on line 251 refers to If you need any additional information let me know please.
Visual Studio 2015 doesn’t install C++ by default. You have to rerun the setup, select Modify and then check Programming Language -> C++

Does std::stoi throw an error on the input “abcxyz”? Yes. I think your confusion may come from the fact that strtol never reports an error except on overflow. It can report that no conversion was performed, but this is never referred to as an error condition in the C standard. strtol is defined similarly by all three C standards, and I will spare … Read more
The preprocessor is a program that takes your program, makes some changes (for example include files (#include), macro expansion (#define), and basically everything that starts with #) and gives the “clean” result to the compiler. The preprocessor works like this when it sees #include: When you write: The contents of some_file almost literally get copy pasted into the file … Read more
