function does not take 1 arguments c++
You declared this at the top: So the compiler expects stringChar and stringVal functions to have no arguments. Change the declaration to:

Converting a Cubemap into Equirectangular Panorama
Assuming the input image is in the following cubemap format: The goal is to project the image to the equirectangular format like so: The conversion algorithm is rather straightforward. In order to calculate the best estimate of the color at each pixel in the equirectangular image given a cubemap with 6 faces: Firstly, calculate polar … Read more
not declared in this scope’ when using strlen()
You forgot to include <cstring> or <string.h>. cstring will give you strlen in the std namespace, while string.h will keep it in the global namespace.
c++ a heap has been corrupted error when running the program
I have not reviewed the whole code, but there are tools available that can help you in this situation that track the usage of memory and indicate if something went wrong. One example is valgrind that is at least available for Linux environments. Anyway, this tool allowed me to find at least one bug in … Read more
operator << must take exactly one argument
The problem is that you define it inside the class, which a) means the second argument is implicit (this) and b) it will not do what you want it do, namely extend std::ostream. You have to define it as a free function:
Getting a bunch of crosses initialization error
The C++ standard says: It is possible to transfer into a block, but not in a way that bypasses declarations with initialization. A program that jumps from a point where a local variable with automatic storage duration is not in scope to a point where it is in scope is ill-formed unless the variable has … Read more
How do I deal with “signed/unsigned mismatch” warnings (C4018)?
I work with a lot of calculation code written in c++ with high-performance and low memory overhead in mind. It uses STL containers (mostly std::vector) a lot, and iterates over that containers almost in every single function. The iterating code looks like this: But it produces the signed/unsigned mismatch warning (C4018 in Visual Studio). Replacing … Read more
Too many arguments to function
On the header file you declare: But on the implementation is: Change the header file to
Source file not compiled Dev C++
I just installed Dev C++ and I am learning C programming. the code i used was I saved it as a .c file. When I compile it works fine, but when I compile and run it says source file not compiled. So I googled buncha things and came across this video on youtube which shows … Read more
‘cout’ does not name a type
The problem is that the code you have that does the printing is outside of any function. Statements that aren’t declarations in C++ need to be inside a function. For example:
