    continue

    i dont really understand what the continue keyword does but i think it basically tells a loop to continue (from the short man page on it). If this is right, is it a good keyword to use or no because it kinda seems like goto to me (but what do i know). thx for answers.

    the continue keyword is similar to break except that instead of completely breaking out of the loop, it continues on to the loop's next part (fairly obvious). Note that continue can't be used in switch statements.

    More specifically, continue will cause execution to jump back to the beginning of the loop, skipping whatever may have come after it...

    ie:


    Code:
    int
     stringlen(const char * str)
    {
      int count = 0;
      int i = 0;
          while(1)
        {
               if( str[i++] != 0 )
             {
               ++count;
               continue;
             }
           break; //...this won't happen if str[i] != 0...    
        } 
     return count;
    }
    Code:
    bool fun(bool value)
    {
        return std::pow(std::exp(1), std::complex<float>(0, 1) 
        * std::complex<float>(std::atan(1)*(1 << (value + 2))))
        .real() > 0;
    }
