Problem: I need to cast only one char to string. The opposite way is pretty simple like str[0]. The following did not work for me: char c = 34; string(1,c); Do you guys have any idea how can I convert a character into a string? I would be grateful if you could solve the issue. I’ve already spent thirty minutes on this. Please, someone, come ahead and save my day. Thanks.
