How to get the first letter of the string?
Is there any standard function(or way) to get the first letter of a given string?
I tried splitting the string, but that didnt work..
@ QStringList lineList=line.split(""); //the "line", i read it before from a file
std::cout<<"the first word of the line :"<<lineList.at(0).toStdString()<<endl;@
If anybody knows, plz tell me...
Simple answer: line.at(0)
Complex answer: What do you understand a letter to be?
With unicode one QChar can be any one of these:
- something simple as e.g. 'A'.
- fun stuff like 'LATIN SMALL LIGATURE FFI' (U+FB03) which would most likely be counted as 3 letters by most people
- only part of one complex glyph (the drawing commonly referred to as "letter"). E.g. you could write 'Ö' (LATIN CAPITAL LETTER O WITH DIAERESIS, U+00D6) as LATIN CAPITAL LETTER O, U+004F followed by COMBINING DIAERESIS, U+0308
- or even just "half a unicode codepoint" when surrogate pairs are in use, which extend the 16bit unicode space that is addressable directly by UTF-16 used in QString by combining 2 UTF-16 characters.
operator or at()
index number is of course zero
Thanks a lot for all of u...:)
i did like this
std::cout<<"the first word of the line :"<<line.at(0).toAscii()<<endl;
