Why did the Comparison between pointer and integer error occur?

Question

C++ / C#

Hi everyone! I'm learning c++builder
I got this error:
[bcc32c Error] bcbl.cpp(47): comparison between pointer and integer ('int' and 'const char *')
Code:

String str = "text,text";
if (str[4] == ",")  // ошибка

what am I wrong and how to compare correctly?

Answer 1

Str[4] == ','
The character must be written in apostrophes, not quotes. Strings are written in quotes, for example, str == "abcde".

Answer 2

Problem solved, instead of ',' nuno ','
