how compare simples aspes?

how can i compare simples aspes?

string text= "safdsA var ifl  ; -.67Ç  68.9\"hello \"\" mother!!!\" \'d\' afdsafd , if do";
for( CharacterIndex=0;CharacterIndex<(int)text.size();  CharacterIndex++)
        {

            //Getting Char:
            if(text[CharacterIndex]=='\'' && blnChar==false)
            {
                cout<< "char";
                blnChar=true;
                Tok.Name+=text[CharacterIndex];
                Tok.Type=Token::Char;
            }

the 'cout' isn't printed, because i belive "text[CharacterIndex]=='\''" is wrong :(
but i don't understand why.. can anyone correct me?

double check the value of blnChar.
\' is the single quote escape, so yes, '\'' is correct.

It wouldn't have taken much effort on your part to produce a minimal compilable example to test your code.

#include <iostream>
#include <string>
using namespace std;
int main()
{
  bool blnChar = false;
  string text = "safdsA var ifl  ; -.67Ç  68.9\"hello \"\" mother!!!\" \'d\' afdsafd , if do";
  for (int CharacterIndex = 0; CharacterIndex < (int) text.size(); CharacterIndex++) {
    //Getting Char:
    if (text[CharacterIndex] == '\'' && blnChar == false) {
      cout << "char found at " << CharacterIndex << endl;
      blnChar = true;
      //Tok.Name += text[CharacterIndex];
      //Tok.Type = Token::Char;
    }
  }

  return 0;
}

$ g++ foo.cpp
$ ./a.out 
char found at 51

So if you're not seeing the printout, you need to post your real code.

I don't what simples aspes are, but '\'' is indeed the character literal for an apostrophe.

What would you expect to happen in the following code?

// Example program
#include <iostream>
#include <string>
using namespace std;

enum class Token {
    Char
};

struct TokenInfo {
    std::string Name;
    Token Type;
};

int main()
{
    bool blnChar = false;
    string text= "safdsA var ifl  ; -.67Ç  68.9\"hello \"\" mother!!!\" \'d\' afdsafd , if do";
    TokenInfo Tok;
    
    for( int CharacterIndex=0;CharacterIndex<(int)text.size();  CharacterIndex++)
    {
        //Getting Char:
        if(text[CharacterIndex]=='\'' && blnChar==false)
        {
            cout<< "char";
            blnChar=true;
            Tok.Name+=text[CharacterIndex];
            Tok.Type=Token::Char;
        }
    }
}

now 'cout' is printed:

void ValidCharacters(string text)
    {
        Tokens Tok;
        int CharacterIndex=0;
        cout << text << "\n";
        bool blnString =false;
        bool blnNumber =false;
        bool blnChar =false;

        for( CharacterIndex=0;CharacterIndex<(int)text.size();  CharacterIndex++)
        {

            //Getting Char:
            if(int(text[CharacterIndex])==39 && blnChar==false)
            {
                cout<< "\nchar\n";
                blnChar=true;
                Tok.Name+=text[CharacterIndex];
                Tok.Type=Token::Char;
            }
            else if(blnChar==true)
            {
               Tok.Name+=text[CharacterIndex];
               Tok.Type=Token::Char;

            }
            else if(int(text[CharacterIndex])==39 && blnChar==true)
            {
                blnChar=false;
                Tok.Name+=text[CharacterIndex];
                //Tok.Type=Token::Char;
                TokenList.push_back(Tok);
                Tok.Name="";
                //Tok.Type=Token::ID;
            }

but the next Tok.Type will be Token::Char instead different :(
i change it from '\'' to '39'.. now enters

[jonnin]

that is interesting. locale issue?
what does this print?
int wtf = '\'';
cout << wtf << endl;

all your code sets it to type = Char or the last block does nothing, so it is whatever at that stage. set it to what it needs to be in each block -- you can optimize removal of excess assignments later with a careful trace.

from these text:
string text= "safdsA var ifl ; -.67Ç 68.9\"hello \"\" mother!!!\" \'d\' afdsafd , if do";
i need get the: " 'd' " token or:
string text= "safdsA var ifl ; -.67Ç 68.9\"hello \"\" mother!!!\" \'\t\' afdsafd , if do";
get the " '\t' "... i update the code:

//Getting Char:
            if(int(text[CharacterIndex])==39 && blnString==false && blnNumber==false)
            {
                Tok.Name=39;
                CharacterIndex++;
                Tok.Name+=text[CharacterIndex];
                CharacterIndex++;
                Tok.Name+=39;
                Tok.Type=Token::Char;
                TokenList.push_back(Tok);
                Tok.Name="";
            }

now my problem was resolved ;)
like everyone see, i just change the ' text[CharacterIndex]=='\'' ' to "int(text[CharacterIndex])==39".
the special characters is best compared converted to a ASCII number(int(CharLetter)))
thank you so much for all
