Specifically, the goal here is to create a linked structure that has some number of nodes, between 5 and 2 million. Don’t worry that this number is large or that values may wrap around past the max size of integer. If you have created your linked structure correctly, a modern computer can breeze through this … Read more
So, I’ve figured out the issue and it was a combination of bad logic and not being totally familiar with the automake/autotools world. I was adding the correct files to my Makefile.am template, but I wasn’t sure which step in our build process actually created the makefile itself. So, I was compiling with an old … Read more
I want to evaluate a string with a switch but when I read the string entered by the user throws me the following error. error: invalid cast from type ‘std::string {aka std::basic_string}’ to type ‘int
Add this line before main function: This is called forward declaration: compiler needs to know function prototype when function call is compiled.
Well, data.str().c_str() yields a char const* but your function Printfunc() wants to have char*s. Based on the name, it doesn’t change the arguments but merely prints them and/or uses them to name a file, in which case you should probably fix your declaration to be The alternative might be to turn the char const* into a char* but fixing the declaration is preferable:
Authors suggest there to use GLAD library, because this library provides creation of GL context (which does not fit me) No, GLAD does not create or manage GL contexts in any way, and the website https://learnopengl.com/Getting-started/Creating-a-window never claims otherwise. They use GLFW for context and window management. Does compiler really cannot get addresses of Opengl functions from … Read more
You need header guards on that header file. It is presumably being included twice. Modify the header, adding these lines to the beginning and end. The define doesn’t need to be STUDENT_H… it just needs to be unique. With these directives added, the compiler will ignore all contents of the header file if it has already been parsed. … Read more
You can convert char to int and viceversa easily because for the machine an int and a char are the same, 8 bits, the only difference comes when they have to be shown in screen, if the number is 65 and is saved as a char, then it will show ‘A’, if it’s saved as … Read more
Taking my first C++ class in college. I need to download C++ and my teacher gave us a direct link to download it, but it only works on Windows. Is there a way I can format it to work on my Mac or is there a Mac-friendly version I can download?
Let’s say that I need to format the output of an array to display a fixed number of elements per line. How do I go about doing that using modulus operation? Using C++, the code below works for displaying 6 elements per line but I have no idea how and why it works? What if … Read more
