help you fix your problem I am new to PHP and I am somewhat understanding it. Now I am working on something but I keep getting a error message saying Parse error: parse error, unexpected T_ECHO in C:\wamp\www\mymoney.php on line 11. Now I am looking at line 11 and I don't see anything i am doing wrong. So I was woundering if someone can help me understand what I might be doing wrong thanks.
C lang - sprintf creates 8 char-long string instead of 6, when applied to negative int
it should still fix some issue sprintf(string, "%06x", -1); prints at least 6 characters. %x implies an unsigned number. (unsigned) -1, in hex, is FFFFFFFF on a 32-bit unsigned machine. When scanf() gets to the "%06x", "The unsigned int argument is converted to unsigned octal (o), unsigned decimal (u), or unsigned hexadecimal notation (x or X) in the style dddd; ..." C11dr §220.127.116.11 8
To fix the issue you can do I recommend to use arrays of char and pass them to your function as parameter. You local array char firstName[MAX_STRING]; goes out of scope if getFirstName terminates. This meas the variable is not longer accessible after getFirstName has terminated and a pointer to the variable is undefined behaivoir.
I wish this help you I was planning to display information of AR object in screen with arrow in 2D. So I used projectPoint to get corresponding position of object in screen. I have this function to return convert 3D position of node to 2D and CGPoint to display info text in. , path.addLine(to: s) s here had reversed y so this did the trick
let frame = self.sceneView.frame
let sInversed = CGPoint(x: from.x, y: frame.height - s.y)
