I'm writing a C++ wxWidgets calculator application, and I need to store the characters for the operators in an array. I have something like `int ops[10] = {'+', '-', '*', '/', '^'};`. What if I wanted to also store characters such as `√`, `÷` and `×` in said array, in a way so that they are also displayable inside a `wxTextCtrl` and a custom button?
