How to take a single character by index in a QString?

Question

Programming

There is a string, it is necessary to check the presence of brackets in it, I wanted to compare each character from the string with brackets

Answer 1

What about str[0] doesn't suit you? It seems exactly what you need ...
If you need to check for the presence of at least one required character in a string, the indexOf method already implements what you want to do yourself.
